The DSE899 does not have an RS232 port, hence we need to use a DTECH DT-9000 RS232 to RS485 converter.

Terminate communication wires at breakout board provided in harness accessory kit. Use breakout board cover to protect connections and secure to service port.

Some H Panels may have an optional dial-up modem installed. Make sure to turn off the modem before connecting DB9 connection to the RS232 port outside of the H panel.
