How to set up RS-232 and RS-485 serial and USB ports
The RS232 port is used to connect an external printer to the control panel for printing active events and loop map. The RS485 port allows up to 4 repeat indicator panels to be connected to the control
panel for repeat indication and messages of system events. Note some messages displayed at the repeat indicator panel are worded slightly different but they mean exactly the same, see Appendix C.
The USB port is for the Commissioning tool. You will need to be at access level 3 or above to set-up the serial ports.
