Module Conﬁguration Switches

The RS1 Module utilizes a four position DIP switch (see ﬁgure

below) to conﬁgure the baud rate, protocol and checksum. These

switches must be set to match the application settings. Refer to the

paragraphs that follow for details.

Important:

When you make changes to the switch settings, use a blunt,

pointed instrument (not a pen or pencil).

DIP Switch Location (Back of Module)

Setting the Baud Rate – SW1 & SW2

DIP switches SW1 and SW2 set the baud rate. Using the table below,

conﬁgure the module for your application. Selection of the “EPROM

Mode” (SW1 & SW2 are On) will cause the baud rate, protocol and

checksum settings to be read from the RS1 parameters listed below.

Note that these parameters must be programmed for correct

operation.

Checksum will be read from P109 - [EPROM Checksum]

Protocol will be read from P108 - [EPROM Protocol]

Important: If an “AIC+” is being used and “EPROM

Mode” is selected, SW3 must be set to “On” to enable

software handshaking.
