MX4428 MXP Engineering / Technical Manual

 

MXP Loop Filter Board

Note – if you are fitting the board to an MXP in a responder box, you may need to tip the underside of the plastic standoffs inwards to get the board to fit into the MXP board connector easily – it will help if you rotate each standoff so that its plastic latch is pointing away from the edge of the board. Once the board is inserted you can straighten the standoffs before tightening the screws on the MXP loop wiring terminals.

Be sure to check that the system is operating normally, and that the problem you started with is solved.

10.3DIAGNOSTICS

Connect a terminal or laptop running a terminal emulator program to the MXP diagnostics port using LM0041. Select baud 19200, no parity, 8 databits, 1 stop bit.

Enter the command RS. This will reset the error counters. Wait a few minutes. Enter TC. The “Total reply fail count” count should be zero. Keep checking it periodically. It should not increase by more than about 1 per hour. If there is a problem the count may increase every few seconds. To try to correlate the errors/retries with other events you can keep typing TC (or Control-R to repeat the last command) and see when the errors are occurring.

Alternatively to try to correlate the errors/retries with other external events you can enter the command NC (Nosex comms log toggle) so that the Nosex comms log is enabled. Then you will see activity on the screen in real time every time a device does not reply. (Note - one device that should not be present is polled every 5 seconds, it should not reply and this lack of reply is displayed on the screen). Be sure to type NC again so that the Nosex Comms log is disabled before disconnecting the terminal.
