Note only the A,B and 0V DC Connections are 
Used. 0V DC between master and slave should 
be connected for correct operation and to prevent 
damage to both master and slave systems

The TOC 635 controller has an in-built memory map allowing access to alarm status, panel status, readings etc 
using Modbus RTU protocol. Wiring between units is as follows:

MODBUS INTERNAL MEMORY MAP ADDRESSES
