7.3 Connection to the RF Receiver (for XMT-SI-RF)
You can install up to 32 XMT-SI-RF probes on CN7.
NOTE: The MAXIMUM number of probes that can be installed in the console is 32.
The RF receiver can connect directly to the CN7 terminal block connector. It does not go through the
intrinsically safe barrier (the barrier is not applicable in this installation).
The table that follows shows the wiring connections between the RF Receiver and the LX 4 Console main
board CN7 terminal block:

Refer to the RF Receiver installation manual's section on electrical connections for the correct connections
