Pre-Installation — RS-232 DIP Switch

The RS-232 circuits of the receiver are factory-set to be one-way, transmitter to receiver. If the system has only one receiver, the BI-232 DIP switch on the front panel of the receiver can be set for two-way communication as explained in step 5 of “Installation”.

Figure 2. RS-232 Connector Wiring

1.Turn off all MTPs and devices.

Turn the input and output devices off and unplug their power cords. Verify that all MTPs are disconnected from power sources before proceeding.

2.Connect the transmitter inputs.

•Connect a VGA video source to the Input connector (B).

•Connect a VGA monitor to the Monitor connector (C).

•Connect an RS-232 control device into the RS-232 connector (D). Wire the connector as shown in figure 2.

3.Terminate and connect TP cables between units.

•Connect a TP cable between the Output connector (F) of the transmitter and the Input connector (G) of the receiver. Terminate the cable identically with either standard as shown in figure 3.

•For daisy-chaining, connect up to eight receivers using TP cables between the Buffered

Output connector (H) of a receiver and the Input connector (G) of a daisy-chained receiver.

4.Connect the receiver outputs.

•Connect a VGA display to the Output connector (I).

•Connect an RS-232 control device into the RS-232 connector (J). Wire the RS-232 connector as shown in figure 2.

5.Configure the receiver DIP switches.

See figure 4 for DIP switch (located on the front panel of the receiver) layout and settings.

•H Sync + and V Sync + switches — Set these switches On (up) for positive sync or Off (down) for negative sync.

•S-Video switch — Set this switch ON (up) to output chroma on pin 3 and luma on pin 2. Set this switch OFF (down) to output chroma on pin 1 and luma on pin 2.

•End Unit switch — Set this switch On (up) if either of the following is true:

		Pins:
12345678			Pin	T568A	T568B
				Wire Color	Wire Color
			1	White-green	White-orange
			2	Green	Orange
			3	White-orange	White-green
			4	Blue	Blue
			5	White-blue	White-blue
			6	Orange	Green
			7	White-brown	White-brown
Insert Twisted			8	Brown	Brown
	Pair Wires

NOTE: If you are using Enhanced Skew-Free™ A/V cable, use the TIA/EIA T568A standard only.

•The receiver being configured is the only receiver connected to the transmitter.

•The receiver being configured is the last receiver in a daisy-chained system.

NOTE: Set the End Unit switch Off (down) on the receiver being configured if there are one or more receivers connected to the Buffered Output RJ-45 connector.

•BI-232 switch — Set this switch ON (up) for bidirectional communication or OFF (down) for unidirectional communication.

6.Terminate the power cable and ground the unit.

ATTENTION: See “Power Supply Wiring” in the user guide before wiring.

Wire the 2-pole captive screw connectors as shown in figure 5. Plug them into the Power connectors (A) of the MTPs. The LED indicator on each MTP should be on when receiving power.
