DESCRIPTION

The PV130 RS-232/422 Converter Kit provides a bi-directional electrical interface between RS-232
and RS-422 data ports.

The plug-in power supply, included in this package, allows the PV130 to communicate serial port
data over wire pairs for distances up to 4,000 feet (1,219 m) on the RS-422 side.

User must supply all necessary cable between converter and receivers.
Contents of this package:

Qty Description Part number

1 RS-232/422 Converter EE03-1235-5430
1 12 VDC power supply, 1.2W PS04-1000-0112

INSTALLATION

Refer to Figure 1 during the installation instructions that follow.

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 neces­sary, use a 120-ohm resistor to terminate the line at the receiv er’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 resis­tors 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.

Testing (Refer to PV1000 Instruction/Operation Manual)

1. Ensure that the PV1016 Transmitter DIP switch settings or the PV1004 Transmitter programming are correct for the telemetry type
required by the receiver.

2. Ensure that the PV1000 Transmitter is properly programmed for the COM 2 port baud rate and parity required by the receiver.

3. Confirm receiver PTZ control from a PV1016 Transmitter with front panel keyboard (while off-line) or from the PV1016 Receiver
(while on-line). Check for smooth operation.

Common Causes for Control Problems

No Control

• Transmitter DIP switch settings or programming incorrect for
receiver type.

• Transmitter COM 2 port baud rate and/or parity programming
incompatible with receiver type.

• Converter-to-receiver twisted pair connections reversed or
wired incorrectly.

• Power supply +12 VDC and GND connections to converter
reversed.

Erratic Control

• Cabling between converter and receiver incompatible with
RS-422 operation.

• Wire distance between converter and receiver requires suitable
termination at receiver.

• Wire distance between converter and receiver exceeds
4,000 feet.

• Video coax cable has Coaxitron® or other “up-the-coax”
control information present.
