1Serial port connector — This port is a 3.5 mm, 5-pole captive screw connector for serial RS-232, RS-422, or RS-485 communications. Connect to the port as shown in figure 2-7.

The port serves two functions:

Connects the control panel module to a computer to program the module’s buttons.

Connects the control panel module to the device to be controlled, such as a projector or switcher.

The default settings for all switches for an RS-232 connection is off (0).

DIP switch 3 should be turned on for an RS-485 full duplex connection only, and only if the CTL is the first or last unit in a daisy chain.

DIP switch 5 is a factory reset control. See Factory Reset in chapter 3, Operation.

RS-485 implementation may vary between computers or control systems. Connect the control cable as shown in figure 2-7. If the serial communications link with the control panel module switcher does not work, try reversing the polarity of the TX and RX signal lines.

2Serial port configuration DIP switches —

DIP switch 1 configures the control panel module’s serial port to operate as RS-232, RS-422, or RS-485. DIP switches 2 and 3 are used to terminate the RX and TX lines when the control panel module is at the end of a line of serial devices. The table below defines the switch positions.

Figure 2-8 — Power connector wiring

Do not tin the stripped power supply leads before inserting them into the captive screw connector. Tinned leads are not as securely attached as untinned leads and could slip out.

The two power supply leads must be kept separated while the power supply is plugged into an electrical outlet. Remove power before wiring.

To verify correct polarity before connection, check the power supply’s no load output with a voltmeter.
