Note: Pin 4 on the RS232 dip switch is not used.

Note: The "loop back" RS232 dip switch (RS232 dip switch 1) should be ON for each unit in the chain.

In order to connect multiple switches (up to 15) with RS232 connections to the same CPU, an NTI Matrix-Y-1 cable must be used. Connect the Matrix-Y-1 cable between the RJ45-to-DB9 serial adapter (provided with the RS232 option) and the CPU as shown in Fig. 11.
