Cable Requirements:
The
PROX-1
can operate at up to *500 feet (152 m) of cable, using seven-conductor, shielded, stranded cable. Per the Security Industry
Association’s Wiegand specification, AWG 24 (such as Belden 9537) is the minimum gauge required for data transfer in a 500-foot run
length. However, the proper wire gauge to use must be determined by the current draw requirements of the reader, the length of the cable
run, and the voltage applied to the reader.
If the reader is to be operated at 5 VDC, 5 VDC must be available at the reader (long cable runs have a voltage drop due to the resist-
ance in the cable). A larger gauge of wire (having less resistance) or a separate power supply near the reader may be required to ensure
5 VDC is available at the reader.
Output Formats:
• Wiegand (industry standard 26-bit Wiegand)
• Magnetic Stripe (ABA Track II, clock and data, with card present)
Grounding:
Shield (drain) continuity must run from the reader to the access panel. Shield (drain) and reader ground must be tied together at the
access panel and connect to an earth ground at one point.
Power:
The
PROX-1
may be powered by the access panel. As such, the reader is powered on when the access panel is powered on. However
the best case is to power the reader by a separate, linear power supply.
Voltage:
5 to 14 VDC
Note:
For maximum read range, a minimum of 12VDC is recommended.
FleaPowerTM Control Line:
The
PROX-1
can be placed in a special lower power mode by pulling the purple colored fleaPower Control Line low. This special low
power mode reduces the average power required by the reader.

Note 1:
Read range is stated in a clean RF and electrical environment using Viking Proxcards presented parallel to the
reader surface with the reader operating at 12 VDC. Additionally, read range may be affected by local installation condi-
tions. Range will be less when mounted to metal.
Note 2:
Use of a linear power supply is always recommended.
Note 3:
Minimum current draw is obtained by operating the reader in the fleaPower mode at 5 VDC with the LED off. Peak
current draw occurs when reading a card or tag.
