Configure a serial connection
The “Serial” function is used to describe GMAC-5’s communication link with a UPS or other power system.
Select the protocol and additional serial communication settings. Use the GMAC-5 compatibility table
(Table 6) to find out what protocol is supported by your device.
If you are not sure of the particulars of the connection, use the "Detect" button, which will “talk to” the power
system to determine what protocol it supports. The speed of the power system’s response to the Detect
function can vary. Watch the screen for messages from the auto-detection process. If the Detect function
succeeds, all of the fields in the screen are automatically updated with required values – there is no need to
click "Apply" after detection, detected values (or "Disabled" if nothing was detected) will be saved
automatically.
