9. Close the analyzer enclosure cover.
10. To complete the connections, connect the other end of the current loop wires to a current loop receiver, the serial
or Ethernet to a serial or Ethernet port on a computer, the alarm cables to appropriate alarm monitors and the
validation request input to a switch.
4.13 Configuring the RS-232/RS-485 converter
The Optically Isolated RS-232 to RS-485 Converter is configured for two-wire RS-485. DIP switches on the side of the
converter, shown in Fig 23 → , can be used to set time-out and termination.
Refer to the table Output signal connections (two-wire RS-485 configuration)→ . With the default setting of 9600
baud, the converter will work for baud rates of 9600 and higher.
4.14 Connecting electrical power to the analyzer
The analyzer will be configured for 120 or 240 VAC @ 50/60 Hz single phase input. Check the manufacturing data
label or the terminal block labels to determine the power input requirements. All work should be performed by
personnel qualified in electrical installation.
