Wiring the Host/Config Port

The Host/Config port provides an alternative connection by which the MLC can be configured and controlled from a host device or computer. (The primary means of configuring the MLC is through the USB port; see “Configuring the MLC via the USB Port,” later in this section.) In addition, SIS commands can be issued through this port from the computer to control the MLC (see the “SIS Control” section).

The RS-232 protocol for this connection is 9600 baud, 1 stop bit, no parity, 8 data bits, no flow control.

Use a female 9-pin to bare wire RS-232 cable or a universal control cable (such as

UC 50', Extron part number 26-518-01, or UC 100', part number 26-518-02) to connect a Windows-based PC or an RS-232 control system to the MLC via this 3-pole, 3.5 mm captive screw connector as follows:

1.Wire the RS-232 cable to one of the 3-pole captive screw plugs provided with the

MLC, as follows:

Receive wire to pin 1, which plugs into the Tx (transmit) port

Transmit wire to pin 2, which plugs into the Rx (receive) port

Ground wire to pin 3, which plugs into the _ (ground) port
