Use the tip of a ball–point or other pointed instrument to set these
switches. Do not use a pencil, as lead could jam the switch.
For troubleshooting purposes, we recommend that the programmer
document the required switch settings for each 1771–KA2. Use form
5030, in chapter 10, to record switch settings for the module at each
station. That way, should replacement of the module be required, switches
on the replacements can be set quickly.
Write Option Switch Assembly
The first rocker switch assembly from the left is the write option switch
assembly. (Refer to Figure 3.2). In this assembly, switches numbered 1
through 5 enable or disable different types of write and bit write
commands from being received by, or sent from, the communication
adapter module. (Note that the unprotected read command is not affected
by any of these switch settings.) Switch no. 6 enables and disables daisy
chain operation. See FIRST/SECOND MODULE at end of this section.

The following paragraphs describe settings for these switches.
RECEIVE PROTECTED COMMAND SWITCH
Switch no. 1 of the write options switch assembly determines whether the
module is enabled to receive and execute protected write and bit write
commands from other stations. Set this switch as follows:
