Control Connections
1. Attach the 9-pin side of the converter to the computer’s serial port or to the COM 2 port on
the PelcoVision Transmitter.

2. Wire the receiver’s RX- and RX+ terminals to the converter’s TX- and TX+ terminals. If neces-
sary, use a 120-ohm resistor to terminate the line at the receiver’s RX- and RX+ terminals.
NOTE: Proper operation of an RS-422 circuit requires that the active devices at both ends
of the communications facility be referenced to a common ground, such as earth. If the
ground is established through a metallic conductor, it is recommended that 100-ohm resis-
tors be placed in series with the ground connection at each end (refer to Figure 2). This will
limit any currents that may be caused by other ground paths.
Connecting the Power Supply (See Figure 1)
1. Connect the black/white stripe wire to the converter’s +12 VDC terminal and the solid black
wire to the GND terminal.
2. Plug the power supply into a 115 VAC wall socket or power strip.
