         Thank you for purchasing the PC Timer 8 station sprinkler system controller.


The following steps will aid in installing your new PC Timer.
         -Remove from box and make sure you have the following.
         -PC Timer, CSA/UL Wall transformer, CD-Rom, mounting hardware (3 anchors and 3 screws)

                  [Picture of the components]

          -You will need to purchase a serial cable separately to connect the Timer to you computer. The
length should be fifty feet or less. If you need longer cable test first by before doing a complete installation.
Just install Timer, wall transformer and serial cable.

Find a suitable location in a dry location indoors such as the garage, shed or mechanical room. Access to
the Timer isn’t needed to use the Timer. But access could be required for changing backup battery every
few years.

To mount Timer find a flat surface that will accept the wall anchors and screws provided. Remove front
cover from the Timer by grabbing both the top and bottom halves and pulling then apart. Be careful not to
drop the bottom half with the circuit board.

                  [Picture of Timer with major parts pointed out]

Position the bottom half of the case (part with the circuit board) against a wall and locate the three
mounting holes in the back of the Timer case. Now mark these locations with a pencil on the wall. Use a
¼” drill bit and drill the three locations to a depth of about 1 ½”. Make sure there are no electrical wires or
anything else that may be damaged in the wall before drilling. When done drill the three holes insert the
three anchors into the holes and tap in flush with a hammer. Now position the Timer so that the anchors
align with the mounting holes in the Timer. Put the three screws through the holes in the bottom of the
timer case and secure it to the wall.

Install the user supplied communication cable from the computer to the PC Timer. The cable type is a 9 pin
serial cable with a DB9 male on the end that connects to the users computer and the other end is a DB9
female that connects to the PC Timer. This cable will need to be long enough to go from the Timer to the
computer. The length can be up to 50 feet without any problems. Longer lengths can be used but you
should test with longer cables before installing the timer.
You are now ready to wire up the Timer.

                  [Close up of terminal block]
Power is supplied to the Timer from a plug in wall transformer that is CSA/UL approved. Do not use
another type or brand of transformer. If the transformer needs to be change replace with the same make and

The two wires from the transformer need to be connected to the first two positions on the terminal block
labeled 24Vac. It doses not matter, which order they are connected.
Next connect each of the sprinkler zones to the Timer. Each zone is label 1 thru 8. One wire from each
valve goes to each of the stations and the second lead from the valves goes to common. There are two
commons that are provided for your conviences. Both are the same. Next connect the pump start and/or
master value if they are required.

One thing to keep in mind is if you are using the delay function in the Timer the delay will run after every
station except for the last station (number 8). If this creates a problem with the pump start or master valve,
by allowing the pump to running for the delay time after the last station has ran, put the last station on
station 8. After station 8 runs there is no delay that runs after. This will allow the pump to shut off after the
last station has run it’s time.

                   [Close up of rain switch and red jumper in terminal block]

If you are using a rain switch attach it now. To attach the rain switch remove the red jumper from the 2-
position terminal block and attach your normally closed rain switch in its place. This jumper must be
reinstalled if the rain switch is disconnected. If not the Timer will not allow any watering programs to start.
Now that everything is wired up plug in the wall transformer. You are now ready to install the software on
you computer that will allow you to control the Timer.


To install the software, insert the CD-ROM into your computer’s CD-ROM drive.
The installation program should automatically run, if not manual run the setup on the CD.
This install program will first install the .NET framework 2.0 on to your computer. This is required for the
PC Timer software to install and run. The second part of the software is the control software for the PC
Timer. Once the software installs the next section will show you how to use the software on your computer
and Internet.


Make sure the setup screen is selected. Select it by clicking once on the setup button located at the bottom
left of the screen.

                   [Screen shot of setup screen, pointing out the main parts]

Now you must enter the address of your Timer in the address section at the top of the screen. With out this
six-digit address you will not be able to access your Timer. To get this number look on the circuit board of
your timer.
Once you have done this you will be able to access and control your Timer from the comfort of your
                   {Use the graphics of the buttons below to replace the text in quotes}

The first thing you should do is set the time on the Timer. Make sure the time on your computer is correct
first. Your computer will be used to program the time into the PC Timer. At the bottom of the screen you
will see two buttons labeled ‘Write Computer Date and Time to Timer’ and ‘Read Timer’s Date and Time’
When you click on the ‘Write Computer Date an Timer to Timer’ the current time and date that is on the
computer is transferred to the PC Timer. To check the current date and time on the PC Timer click on
‘Read Timer’s Date and Time’ In about a second or two the Timer will respond with the current date and
time that is has in it’s clock.
                  [Screen shot of pop up for time from PC Timer]

Note: when changing the date and time in the Timer it is possible to that the Timer could miss a start time.
When changing the time in the Timer make sure there aren’t any programs currently running.
Once you have set the date and time in the Timer read it back. If it reads back OK, then the communication
with the PC and Timer is good. If not go to trouble shooting section of this manual.
When you get to here you are ready to set up the programs in the PC Timer for your lawn sprinkler system.


This Timer has four different independent programs with up to four start times each. Each of the four
programs works the same way. There are three main sections to each of the programs. Start Times,
Program Type and Stations Run Times.

                  [Screen shot of program screen, point out main parts]

In the Start Times sections you can have up to four start times for each program. Use the mouse and click
on the arrow pointing up to increase or down to decease the hour an minutes for the start times.
The start times operate on a 24-hour clock and can range from 0hr 00min (midnight) to 23hr 59min (one
minute before midnight).
When entering the start times the times do not have to be in order of time the PC Timer will figure out
which should be first, second, third and fourth. To make the start active (enable it to start) the active check
must be checked. The start time and active will changed to green when active and black when not active.
Note: You don’t have zero the unused start times just make sure that the active box is not check

The Program Type section of the Timer allows you to select whether you would like to water on even days
of the week, odd days of the week, Interval watering or a weekly schedule. Only one out of the four choices
can be active at a time.
When the Even Days Only is selected then water will occur on even days of the week. If Odd Days Only is
selected then water will occur on odd day of the week. This is good for communities that are on and
even/odd water requirement.
Interval watering allow you to choose how often you want to water from once every day to once every 99
days and also allows you to set when you would like to start this type of watering program. You can set
start in 0 days (0 day is today) to start in 98 days in one day increments. For example your could set it up to
water every 3 days and start in 2 days.
The final program type choice is a weekly schedule. When the weekly schedule is selected the user can
choose what days of the week to water on. For example if you would want to water on Mondays and
Thursdays you would select Weekly Schedule and check the Mon and Thu boxes. Checked boxes will
appear green. To uncheck a box, click on that box again.

Station Run Times
There are eight stations available with an adjustable watering time from 0Hr 00Min to 9Hr 59Min in one-
minute increments. Any station that has zero time on it will be skipped. So just select the amount of time
you require for each station and when the watering program starts it will execute these in sequence.
Also available are a separate pump start and master valve control. This will allow you to control a pump for
the larger sprinkler head that can use the dirty lake or river water, and a master valve for the city water that
could be used for drip irrigation and spray heads that would plug up with the water from the lake or river
At the bottom of the Station Run Timers section there is a delay that can be set and ranges from 0Min
00Sec to 59Min 59Sec in one-second intervals. If programmed allows for a delay between stations so that
slower valves can close before the next valves open.
Note: If using the Pump Start or Master Valve control that control will remain on during the time that is set
on the delay, even if the next station where to use the other control. If this is a problem them put the last
sprinkler zone on station 8 as this station when done will not run a delay and everything will then shut off.

The controls at the bottom of the screen
There are six controls at the bottom of the screen
The ‘Read’ button will read a program that is in the Timer and display the information on the screen in the
approaite positions. This will also over write anything you may have changed on the screen. To use this
button, select the program that you want to read from the Timer by clicking once on the left side of the
screen. You have four choices Program A, B, C or D. Select your program and then click the ‘Read’ button.
This can be repeated for each of the other three programs. Now you can make changes to your program and
then Update these new value to the Timer by clicking on the ‘Update’ button. This will send the date to the
Timer and the Timer will in turn save it in its memory. {Use graphics for button instead of ‘Read’, etc}
You also have the choice of saving this to your computer’s disk. To save to disk, click on the ‘Save’ button.
A box will appear allowing you to save the current program to disk. You also have the option of changing
the location of the saved file if you want. You can also load a saved program from disk and onto the
computer screen and then Update the Timer with this different program.
The ‘Start’ button will allow you to start the currently selected program in the Timer. Make sure the
information is the same on the screen is the same as what’s in the Timer. If anything has been changed
Update the Timer first.
To stop any program that is currently running just click the ‘Stop’ button. It doesn’t matter what program is
being view on the screen, any program that is running will stop.

Advanced Setup
You will need to access the Setup page for this part. This is where you originally entered the Timer’s
address and selected the serial port. The rest of this is optional but will allow you to customize, setup the
networking and Internet part of the software.
The Device Settings section of the Timer shows the address and port number, these should have been setup
earlier. These should not need to change unless you are changing the port that the Timer is attached to or
replacing the PC Timer with a different one.

                  [Screen shot showing the Setup screen, Crop the device settings]

Just down from there are the labels that can be change to allow the user to customize this program for their
lawn sprinkler system. Here you can change the eight labels for the stations and the four for the programs
to something more meaningful. To change any label just type over the default names with your own. You
could change Station 1 to Front Yard, and then when you are looking at your watering program you would
see Front Yard instead of Station 1. This can also be done with the four program labels and it will give you
a customized look for your Timer.

Remote Administration Settings

                  [Screen shot with the Remote Administration Settings, Crop the Remote Administration

This section will allow the Timer to be set up so that it can be access through a network. Here you need to
select a port (not to be confused with serial ports) that the program will use to communicate. You can select
any port that isn’t currently being used. You may need to away from the ones used for web pages (port )
and email (port      ). Next you will need to makeup a username and password so that you can login and get
access to the Timer over a network. This could be your own home network or the Internet. Now all that
needs to be done is check off the Enable web based remote administration box. This will allow the PC
Timer software to receive a connection from the network. If you are behind a firewall and/or router you
will have to configure it to allow a connection to come in on the port that was selected. Since there are so
many different firewall and routers, you will have to consult your firewall and/or router information on how
to do this. We do not support other companies’ products. You are now ready to use the PC Timer over a
network. The requirements for the remote computer (the one without the PC Timer attached) are a network
connection between the two computers setup for HTTP and a web browser. To test and see if PC Timer
software is setup correctly, do the following on the computer with the Timer attached. Open up a web
browser and type the following into the location bar.

                  [Screen shot showing what the login screen looks like]
The 8000 are the port number used for the connection if yours is different enter your port number you
selected. If everything is OK you will get a Login screen asking you for your username and password the
get access to your Timer. After this you should get a screen like below. This is the web interface of your PC

                  [Screen shot of Login screen for Login into user’s computer]

The Setup screen will appear from here you can do some things that can be done in the PC Timer interface
with the addition of a button to Read Timer Status. This allows you to read back the important information
from the Timer that you can’t get since you are at a remote location. The Status will return information
such as weather the rain switch is wet or dry, the Timer is running a program and if so what program is
currently running and what station it is currently on.
This web interface will allow you to Read, Update, Start and Stop the PC Timer the only thing that can’t be
done is file access via the web interface. The interface is a little different in that you have to type in the
numbers and the selections for master valve and pump start also have a disabled selection. This was to
make the interface simpler and enable it to run on older browser.

Website Account

This section allows you to track you computer’s IP (Internet Protocol address). This is only need if you
need if you don’t know your Internet address. If you know your computer’s Internet address or have some
way of keeping track of it when it changes then you don’t need a Website account on our server. But if
your ISP (Internet Service Provider) gives you a dynamic address (changes at their discretion) then you will
need some way of tracking where your computer is on the Internet. To do this you will need to setup an
account on our server and we can do this for you. Once you account has been setup you will need to enter
your username and password into the Website Account section in the Setup page of the PC timer. This
username and password are different from the Enable web based remote administration section. Once this
is done set how often to check your computer’s IP address. A setting of 60 minutes should be good for
