Installation and Wiring 3–3

Setting the Protocol – SW3

As shown in the table below, SW3 sets the protocol being used (point-

to-point or multi-drop). If EPROM Mode is active (SW1 & SW2 are

On), the 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.”

Selecting the Checksum Mode – SW4

Switch SW4 sets the checksum mode. Conﬁgure this mode to be

consistent with your communications and application. If EPROM

Mode is active (SW1 & SW2 are On), the checksum mode will be

read from P109 - [EPROM Checksum] (SW4 will have no effect).
