Serial Port - Loop Back Test
- Performs a test to verify either the RS-232 or the RS485/422
serial communications functionality from the 15-pin connector (Port 2) on the panel is
operating correctly. A loop back connector inserted into the port is required for proper testing.
Wiring diagrams to build RS-232 and RS-485/422 loop back connectors are shown below.
PLC Enquiry Test
- Tests the communications with the selected PLC protocol between the
panel and a connected PLC.
Buzzer Test
- Use this option to test the internal audible beeper of the panel.
