3.0 PRO101 – Multi-Channel RS-485
Operation
3.1 Overview
It is possible to network up to 16 PRO101 programmers on an RS-485 network and control
them from a single 'Supervisor PC' running a single session of the EQTools/ISP-PRO
software. This scenario requires that each PRO101 programmer is set to 'RS-485' and that a
unique 'Node Address' is set for each programmer. An RS-232 to RS-485 convertor is
required to convert the RS-232 signal from the PC COM port to an optically isolated RS-485
signal suitable for interfacing with the PPM's on the network.
The typical setup is shown in the figure below:
