RS-232 connectors — Connect one or two host devices, such as computers,

 

touch panel controls, or RS-232 capable PDAs to the switcher via these

 

3-pole captive screw connectors for serial RS-232 control (figure 2-7). Use the

 

supplied tie-wrap to strap the serial cable to the extended tail of the connector.

NThe length of exposed wires is critical. The ideal length is 3/16” (5 mm).

•If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit between them.

•If the stripped section of wire is shorter than 3/16”, wires can be easily pulled out even if tightly fastened by the captive screws.

NThese two ports are hardwired for RS-232 only.

The RS-232 Secondary port is active only if the front panel Configuration port is not in use. If a front panel configuration connection is made, the rear panel RS-232 Secondary port becomes inactive and the front panel Configuration port is active.

NThe switcher can operate at 9600, 19200, 38400, or 115200 baud rates.

See “Selecting the RS-232 Primary port’s baud rate” in chapter 3, “Operation”, to configure the RS-232 Primary port from the front panel.

See “Command/Response table for IP SIS commands”, in chapter 4,

“SIS Programming and Control”, to configure all ports under SIS control.

If desired, connect an MKP 2000 or MKP 3000 remote control panel to the switcher’s RS-232 connector. Refer to the MKP 2000 Remote Control Panel User’s Manual or the MKP 3000 Remote Control Panel User’s Manual for details.
