6.2 DIP Switches


There are three DIP switches on the control board. The usage of each switch is as tabulated:

SW1

8-way

To set the Device ID

SW2

4-way

To set the baud rate and communication type

SW3

8-way

To set the type of serial communication (i.e.
whether RS232, 422 or 485)


The following tables show the settings for each of the three DIP switches.
Note that a "-"indicates an "OFF" position.

Table 1: SW1 (Device ID)


SW1 is used to set the Device ID of the device. It has a row of 8 DIP switches. The range of Device IDs that
can be set is 0 to 255. However, the acceptable range for field operation is 1 to 254. The Device ID is set
according to the binary format of an 8-bit byte. An "ON" position is interpreted as binary bit 0. To help you
to find the dip switching settings for a particular Device ID, use the index value associated with each bit.
