The base address is the address on which the collected Lambda values will be
retransmitted. This address must lie on a 16 message boundary (i.e. the
address, in hex, must end in 0). The base address also defined the addresses
of the Collect slave units that the master will monitor. The recommended
address is Hex 460.

The message rate is the rate at which the Lambda values are retransmitted on
the CAN bus to the measuring device (usually an ADL or ECU).

Messages 1 to 4 do not need to be configured on the master unit.

Output to Transmit must be LA V1, with 3 decimal places in the table setup.

The master PLM unit will briefly display “CU 1” (Collect Unit 1) on start-up after
displaying the firmware version.

If the slave PLM stops transmitting to the master PLM for 1.5 seconds then the
master PLM will retransmit a value of 0 for the missing slave.

Configuring the CAN Collect slave units (PLM 2
to PLM 16)

The Message 1 tab of the CAN Message Setup dialog must be configured as
follows:

Address

Master PLM Collect Master Base Address + PLM

PLM 5 address would be Hex 464
