ATTENTION:
•
Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall
cavities.
•
Sauf mention contraire, les adaptateurs CA/CC ne conviennent pas à une utilisation dans les espaces
d'aération ou dans les cavités murales.
•
Remote power is intended for indoors use only. No part of a network that uses remote power can be
routed outdoors.
•
L'alimentation à distance est exclusivement réservée à un usage en intérieur. Un réseau utilisant une
alimentation à distance ne peut pas être routé en extérieur.
NOTE: One power supply is included with the transmitter and can normally power both units, if they are both
from the Extron DTP3 series.
See figure 7 to wire the captive screw connector and secure the power cord to the extended tail of the connector.

1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
3. Slide the leads into the supplied 2-pole captive screw plug and secure them, using a small screwdriver.
4. To verify the power cord polarity before connecting the plug, connect the power supply with no load and
check the output with a voltmeter.

Use a female 9-pin D connector to bare wire RS-232 cable or a universal control cable (UC50' or UC100') to
connect your computer or control system to the OVER DTP3 port.
1. Wire the unterminated end of the RS-232 cable to the 3-pole captive screw plug as described below:
a. Connect the transmit wire from the RS-232 device into the Rx pin of the device.
2. Connect the receive wire from the RS-232 device into the Tx pin of the device.
3. Connect the ground wire from the RS-232 device into the G pin of the device.
4. Plug the 3-pole connector into the RS-232 port on the rear panel of the transmitter or receiver.
5. Connect the other end of the cable to a control system or the device being controlled.
NOTE: The length and preparation of exposed wires is important (see the
