“Control by:”
For the “MCPAs’ MUTE” and “Reflected Power Alarm Reset” commands, the
user can set the preferred control method by choosing Software or Hardware
in the “Control by” field.
a. If the user chooses hardware control, the controller will respond to the
opto-isolated inputs located in the DB-25 to screw terminals break-out
board and the software commands for these two parameters will have
no effect.
When “Control by Hardware” is selected the MCPA is automatically
unmuted unless the corresponding opto-isolated input is energized.
b. On the other hand, if the user chooses software control, the controller
will respond to these software commands instead of to the opto-
isolated inputs.
