Pro-Call 5X2 SMS / GPRS Communicator.
The Pro-Call 5x2 SMS / GPRS communicator is a reliable and cost-effective method of multiple two-way communications for Man to Machine and Machine to Man applications. The 5x2 can be used for industrial and security applications to monitor alarm, temperature, pressure, and other process signals. The 5x2 has five Inputs and two relay outputs and in addition one permanent analogue input that measures the supply voltage to the 5x2 communicator.

1. INPUTS.
The five inputs each have two programmable messages that can be configured as follows.

a. Five Digital inputs with 0 DC volts equaling a low and any voltage above 3 VDC equaling a high signal.
The 5x2 will send one message for a low and another message for a high. Each digital input can have a pre-programmed debounce time programmable from 0 (=500 Milliseconds) to 999 seconds or about 16 minutes. This means that should an input go High the input can ignore this for example, 10 seconds and if the input is still high after the 10 seconds has passed then only send a signal. This is very useful for delaying the sending of a Mains fail signal for 2 to 5 minutes.

b. Three digital and two analogue inputs.
The digital inputs are as per 1a above. The analogue inputs can be set to send a message at any voltage between 0 and 30 Volts DC in .1 VDC incremental’s. This means that they can be programmed to send at 1.5 VDC for a low and at 7.5 VDC for a high. The analogue inputs can be used to directly read outputs from industrial applications that either give a voltage output or a 4 to 20 mA output.

c. Any one or all of the inputs can be programmed to count pulses and either to report the
count on a status signal or to report when a preprogrammed count total has occurred. The maximum count on each input is 65500 The inputs can be individually configured to count on a high or low or both. Note 1: When counting on both, the input will count 1 for high and then 1 for low. Note 2: Correct programming for the input messages is needed for this as well as the correct programming of the count values and whether to count on a high or low or both.

d. The two analogue inputs can also be configured to give percentage readings. e. The internal supply or battery voltage input can be programmed to send a low and a high signal at any voltage from 0 to 30 VDC however when using the 5x2 on a normal 12 VDC battery this should be set to send a Battery low at around 12 VDC and a Battery OK or High at 13.5 VDC. 2. OUTPUTS.
The 5x2 also has two relay outputs both capable of switching a 1 amp 125 VAC load. Uses are: • Alarm activation/Deactivation, • Open/close electrically controlled doors, • Lock/Unlock electrically controlled locks, etc. • Switching lights on or off. The two outputs can be controlled via SMS to either latch on or off or to pulse. Output 1 can also be controlled via a dropped call from any number that is programmed into the 5X2 to receive messages. There are 3 connections to Output relay 1 = Common / Normally Open / Normally Closed. There are only 2 connections to Output Relay 2 = Common and either Normally open or normally closed selectable with a link. a. Switching Outputs On Both outputs can be switched on separately. This is done by simply sending an SMS containing the four digit pin, output number (Output 1=A, Output 2=B) and on (on = 1). For example: $ihpsA1 will switch output 1 on, if the four digit pin is ihps (ihps is the factory default pin). After the output is switched on, the relevant SMS will be sent to all programmed cell numbers. Output 1 can also be activated by phoning the 5x2 from a cell number that is programmed into the 5x2. The 5x2 will drop the call after it recognized the number and then activate output 1. The output can be set to switch on when phoned once and stay on. When the 5x2 is phoned a second time, it will switch the output off. Or the output can be set to pulse when phoned once, meaning it will switch on and off within a programmable time interval. b. Latching operation When latching operation is selected, the 5x2 will respond as follows to a dropped call: • First received call will switch output 1 on, • A Second call will switch output 1 off. • A Third call will switch it on again and so on. c. Non-latching operation When non-latching operation is selected, the 5x2 will respond as follows to a dropped call: • One dropped call will switch output 1 on and off within a programmable time interval (Pulse).

d. Onboard Dipswitch Latching and non-latching operation can be selected by changing the onboard dip switch setting. By setting switch number 1 to On, non-latching operation is selected and by setting switch 1 to Off, latching operation is selected. When switch 2 is set to Off, no SMS will be sent when output 2 is switched on, switched off or pulsed via a dropped call. When switch 2 is set to On, an activation SMS will be sent every time output 1 is switched on, switched off or pulsed via a dropped call. e. Switching Outputs Off Both outputs can be switched off separately. This is done by simply sending an SMS containing the four digit pin, output number (Output 1=A, Output 2=B) and off (off = 0). For example: $ihpsB0 will switch output 2 off, if the four digit pin is ihps (ihps is the factory default pin). After the output is switched off, the relevant SMS will be sent to all programmed cell numbers. f. Pulsing Outputs All outputs can be pulsed separately. Pulsing will switch the output on and off within a preprogrammed time interval. The pulse duration is programmable from 1 to 99999 seconds. If the output was on before sending the pulse command, it will switch off. This is done by simply sending an SMS containing the four digit pin, output number (1=A, 2=B) and pulse (pulse = 9). For example: $ihpsB9 will switch output 2 on and off within the preprogrammed time interval, if the four digit pin is ihps. After the output is pulsed, the relevant SMS will be sent to all programmed cell numbers. g. Output Relay 2 Programmable timer. Output Relay 2 has a programmable 7 day timer that can be set to activate 4 times per day for up to 99999 seconds each time. 99999 Seconds is just over 27 hours and 46 minutes. Applications for this are to Pulse open a gate at 7 AM and to pulse the gate closed at 9AM then to pulse open the gate at 4PM and to pulse close the gate at 6 PM. This output can also be used to randomly 4 times a night switch a light or lights on or off. Programming this output can only be done via the PR Programmer software. Whenever power is applied to the 5x2 it will send itself an SMS to set the date and time of day and the day. Ensure that the 5x2 is programmed with its own number and then re power up the 5x2.

3. Access control
The 5x2 has various levels of access control. 1. Access to the 5x2 unit is by means of a user selectable alpha numeric 4-digit pin code. 2. Any invalid message or invalid command will be answered with Message invalid Please try again. 3. Any Invalid PIN number will not be accepted and the Sender of That PIN number will be informed that he or she doesn’t have access to the system. 4. Any invalid PIN number will be ignored and the cell number of the cell phone trying to illegally access the system, will be sent to the cell numbers programmed into the 5x2 unit. 5. The 5x2 unit can be set to only send between 1 and 999 messages in a 24-hour period, but this feature can be disabled. 6. The 5x2 unit will Only allow 10 Illegal access attempts in a 24 hour period More than 10 in a 24 hour period will be totally ignored.

4. Information request
The 5x2 is also capable of sending various information back to the requesting cellphone. If a valid password is used the unit will reply to all the programmed Numbers and email Address. The following information can be requested. The default pin code is ihps. For example, to request Signal Strength a $ihpsT must be sent to the 5x2.
Request Request Passwords and Unit Number Request Base Numbers and SMSC Numbers Request Cell Numbers Request CCED info Request Input1 to 5 Counter value Request Signal Strength Request Status Report Request Software Version Request Analog Input1 and 2 values Request Battery Voltage Command K I J U P T Y v V b

5. Health test (24 hour test )
The 5x2 can be programmed to send a Test signal SMS at a specific time each day or every 1 to 99 days programmable. This signal is an indication that all is well with the unit. This SMS can be in the form of a simple health message E.G. 24 hour test at Gazzit pump 5. or in the form of a full status report of all inputs. For example, Input1 Low:Input2 Low;Input3 Low;Analog Input4 below 9.0V current: 0.0V;Analog input5 below 11.5V current: 0.0V;Battery voltage above 13.4V current: 13.8V
