TR850 Manual; ml_tr850_01 (January 2005) Approved: C.H. The VCom TR850 is an AMPS Band Transceiver for use in wireless systems. The TR850 integrates an LNA, upconverter, power amplifier, RF and IF diplexers to provide a one-box solution for two-way wireless RF communications. The TR850 and antenna are situated outdoors and connected to a cable modem indoors by standard RG-59 cable. A single RF connector on the weatherproofed enclosure provides the interface to the transmit/receive antenna for rapid setup. The Transceiver is configured to work with standard cable modem frequency plans and levels, permitting direct connection. The Transceiver also includes an RF mute function to reduce power consumption and broadband noise emissions. • • • • +24 dBm output for high reverse channel system gain Low Phase Noise Automatic transmit RF mute (transmits only when an IF signal is present) Fully weatherized unit, suitable for outdoor mounting VCom Inc.

To operate the TR850 in compliance with FCC regulations, you must apply the included label to the antenna. Peel off the protective backing from the label and affix it to the antenna such that the label is readable from a distance of 5 feet. DIAGRAM 2.2C: APPLYING THE SELF-ADHESIVE LABEL VCom Inc.

The power inserter has three connections: DC POWER Connect to wall adapter with RG-59 cable with F connectors TO MODEM Connect to cable modem TO TRANSCEIVER Connect to TR850 WARNING! If the power inserter is not connected correctly, the TR850 will not operate, and there is the potential to damage the cable modem. Ensure that all wires and cables are hooked up before plugging into the AC adapter/power supply (i.e. hook up to the power supply last). After connection, both connectors MUST be waterproofed with the supplied rubber sealing tape. See Section 2.5 for details.

TR850 Manual; ml_tr850_01 (January 2005) Approved: C.H. 12 (. " %) Many transceiver problems can be attributed to environmental conditions (including vibration), which can loosen cables and permit moisture to penetrate the connectors. It is highly recommended to seal the connectors using a technique similar to the one described below. This will provide moisture protection and keep the connections tight. For your convenience, VCom has provided two 6 inch lengths of rubber selfamalgamating sealing tape to use on the two connections of the TR850. STEP 1 Use one 6” section of rubber sealing tape. Starting at the TR850 end, stretch the tape and wrap it around the connector as close as possible to the wall of the TR850. Overlap the tape by approximately one-half of it’s width so that it can form a seal with itself. Extend the wrapping to approximately one inch past the end of the connector. DIAGRAM 2.5A: WATERPROOFING CONNECTION – STEP 1 STEP 2 Cover the sealing tape with electrical tape (not provided). Start approximately one inch further down the cable, and stretch the tape, overlapping by one-half. Wrap to the TR850 end and without breaking the tape, wrap back down to the cable end. DIAGRAM 2.5B: WATEPROOFING CONNECTION – STEP 2 VCom Inc. TR850 Manual; ml_tr850_01 (January 2005) Approved: C.H. 13 STEP 3 When done, the connection should be tightly wrapped with tape, with a good seal to the cable.
