MoTeC PLM - Manual (Page 5)

MoTeC Meter Operation 5
The analog output is provided as a differential voltage using two connector pins
(Analog Out+ and Analog Out-). For correct operation Analog Out- must be
connected to the ground reference on the monitoring system.
The analog output can be configured as a wide band sensor input into a MoTeC
ECU for tuning, as described below. See Appendix F – PLM to ECU Wiring
Details for wiring details.

Digital inputs
Digital Input 1 can be enabled as a switch input or RPM input. If the input is
enabled, the PLM can be configured to operate based on the switch state
(active high or active low) or on a non-zero RPM reading. The RPM reading is
also transmitted in the CAN and RS232 data streams.
Digital Input 2 can be enabled as a switch input, and the PLM can be configured
to operate based on the switch state (active high or active low). This input can
also be configured to change the display units on the PLM display. For more
information, see Setup | Digital Inputs in the PLM Setup Software section.
The digital inputs have a 4.7kohm pull-up resistor, and a switching threshold of
around 2.5volts.
