7. DCS SERIAL PORT: RS-232 serial port. If RS-422 or RS-485 is needed, an external converter should be
used. The DCS serial port is configured as a DTE, DB9 female connector (depending on
the DCS system, a null modem DB9 cable may need to be used for communicating with
this port).

installed, but only the top 2 ports are available for the user.
11. DCS TCP/IP: Ethernet port for DCS communications. RJ45 connector. Supports Modbus TCP/IP
protocol as specified by the Modbus Organization’s “MODBUS MESSAGING ON TCP/IP
IMPLEMENTATION GUIDE V1.0b” publication.
