PC Interface
The PC interface can be found at the HOST connector. A RS-232 (or optional RS-485/422) interface is
on the external of the amplifier. This port is the primary means of communication with the amplifier for
setup and control. The port utilizes an RJ-45 type connector.
The serial cable can be made or purchased for communicating with a PC by configuring a cable with
one end being a male RJ-45 plug and the other end being a DB-9 female connector. Remember that
there is no standard for an RS-485 connector
Note : If required, Glentek can customize a serial port digital interface to adapt to your controller as re-
quired to meet your protocols. We are currently doing this for high speed Ethernet ports.
