6 Meter Operation
Communications
RS232 Interface
The RS232 interface is used for configuring the PLM from a PC, and for
transmitting data to third party equipment.
For configuration from a PC, the PLM can be directly connected using a
standard (straight through) 9 pin serial cable.
See Appendix I – PC Comms Wiring for details on wiring to a PC.
CAN Interface
The CAN interface is used for transmitting data to MoTeC devices such as the
ADL (Advanced Dash Logger) or M800 ECU, or to third party equipment that
supports CAN.
The CAN communications can be configured to allow one PLM unit to collect
CAN data from up to 15 other PLM units, and then retransmit the data on a
single CAN address and on the RS232 interface.
For detailed information on communications interfaces, see the PLM
Communications section.
PLM Display
Start-up Display
On powerup, the PLM displays the current firmware version (eg. 1.1.0) for one
second, followed by a unit number based on the current CAN communications
configuration.
This unit number, displayed for one second, is useful for troubleshooting
networks of multiple PLM units. See the PLM Communications section for more
detail on displayed unit numbers.
Status Display
Whenever the sensor is not in control or is warming up, a series of displayed
codes describes the current status. A description of these codes is given in
Appendix B – PLM Display Codes.
