    Which HP printers can be used with Agilent CMS patient monitors?
    The following printers will work with Agilent CMS patient monitors:
    DeskJet 340                    (C2655A) parallel only
    DeskJet 610C                   (C6450A) parallel only
    DeskJet 695C                   (C4562B) parallel only
    LaserJet 2100TN                (C4172A) parallel only
    LaserJet 5L                    (C3941A) parallel only, must have 2MB memory upgrade
    LaserJet 6L                    (C3990A) parallel only, must have 2MB memory upgrade

    Specifically NOT compatible: DeskJet 700 series

    Non-HP printers are not officially supported, and they must have the following:

•   Support for HP PCL 3 printer language (emulates HP DeskJet or LaserJet)
•   Centronics “B” connector (parallel)
    The usual requirements such as HP serial cable, serial/parallel converter and
    general software revision guidelines for parallel printer support still apply.

    Additional information regarding the serial-to-parallel converter (part number
    5962-4340) includes:

    Due to the missing RS232 interface of the DeskJet 400 and 600 printers, you
    must install a serial-to-parallel converter between the printer and the CMS mon-
    itor. The converter is used to connect the 25-pin serial RS232 printer cable to
    the parallel port of the printer.

    The following table gives the correct settings and is provided for reference:

      8            BAUD rate (19200)                        OFF

    Can you provide an overview of the Power On Mode (cold, warm & hot start)?
    The type of Power On Mode executed depends on the system downtime or the
    detection of a fatal error by the operating system:
    Downtime       Power On Mode

    <1 minute      Hot-start — patient data and active user settings are recovered on restart.
    ≤(<=) 3 hours Warm-start — patient data is recovered, default configurations are restored.
    > 3 hours      Cold-start — patient data is lost, default configurations are restored, and sys-
                   tem performs extended test.

    You can also perform these three different “Power On Modes” manually in the
    Service Mode.

How do I learn my transmitter code?
In order to “learn code” on a transmitter, you must match the transmitter’s fre-
quency with the receiver’s frequency. After you have set the frequency on the
transmitter, follow the steps below.
1. Ensure the transmitter you are working with is not in Monitor Standby sta-
2. Access the Telemetry Frequency Window by clicking on the TELEM FREQ

4. Click on the telemetry transmitter from the displayed list.
5. Click on the LEARN XMIT CODE button.
6. Press the patient button on the transmitter within 10 seconds. If you do not
   press the button within 10 seconds, repeat the procedure.                                                       Go to
