Diagnostic Commands
Switch 4 determines how the KF2 module treats diagnostic commands
sent to it by a remote Data Highway station. You can connect the
asynchronous port of the KF2 module directly to a 1771-KG, 1773-KA,
or 1775-KA communication interface module (Figure 1.2). In such
applications, you can set Switch 4 so that the KF2 module either executes
any received diagnostic commands itself or passes those commands to the
other attached communication module.
