3.0 Serial Communications Ports
3.1 Overview
The PPM3 Programming Module can be controlled from any external device which supports either the
RS-232 or RS-485 hardware communications protocols. The Module features an RS-232 port which
can connect to a COM port of any suitable Control System such as a PC running the Equinox
EQTools software. This mode of operation is restricted to a single programmer channel.
In many medium to high volume production applications there is a requirement to run more than one
PPM3 programmer from the same PC COM port. This can be achieved by daisy-chaining up to 16
modules (using the RS-485 In/Out ports on each programmer) on an RS-485 bus and using an RS-
485 converter to convert the PC RS-232 COM port to the required RS-485 levels. The Equinox ISP-
PRO Software Suite is required to run the programmers in this mode.
The table below details the applications of both the RS-232 and RS-485 communications modes.
