Install Cable
Route the interface cable from the MaxiProx to the Host. Connect the MaxiProx DC power input to the
Host or external power supply. 12VDC or +24VDC can be used.
CAUTION: The P2 shunt jumper is factory installed in the 24VDC position. Failure to install the
P2 shunt jumper in the correct position will permanently damage the MaxiProx unit. The
following states the P2 shunt jumper installation.
Power Supply Voltage
Jumper Position
+24 VDC (21-28.5VDC)
P2 across pin 2 and 3
+12 VDC (11.6-20.9VDC)
P2 across pin 1 and 2
Notes
•
For Wiegand interface cable the maximum length is 500 feet (150m), 50 feet (15m) for RS232, and
4000 feet (1200m) for RS422.
•
When using 5 conductor cable, the power supply and Host must have a common ground (voltage
reference).
•
7-Conductor cable is required when using the
Hold
function or if the ground for the MaxiProx power
supply is not common with the ground of the Host. TB2 terminal 3, Data Return, is to be connected
to the ground of the Host. (Alpha 1296 C or equivalent).
•
7-Conductor cable is required when the
Hold
function is used, and the power supply and Host
"ground" are separate. (Alpha 1297 C or equivalent).
•
A 22 AWG twisted pair, shielded, stranded cable (Belden 9330 or equivalent) is often required for
the tamper switch. Follow the recommendations of the manufacturer of the Host system. If the
tamper input is a supervised input, the "end-of-line" resistor may be mounted in the enclosure
between TB1-4 and TB1-5.
•
The inner diameter of the cable fitting will accommodate a cable with an outer diameter of up to
.260-inches.
2.6
Cable Connections
Install the cable fitting on the rear of the MaxiProx. Feed the cable through the cable fitting. Connect
the wires to the terminal strip with the minimum length necessary. Do not leave extra loops of wire
inside the reader housing. Connect the reader to the Host according to the terminal descriptions in the
dimension diagram. Tighten the fitting to secure the cable. Connect the drain line of the shield to
terminal TB1 Pin 2 (Power Supply Shield). If it is bare, cover it with heat shrink or tape to avoid short
circuits to the other wires. Connect the opposite end of the drain line to the negative terminal and the
frame connection of the power supply.
CAUTION: The P2 shunt jumper is factory installed in the 24VDC position. Failure to install the
P2 shunt jumper in the correct position will permanently damage the MaxiProx unit. The
following states the P2 shunt jumper installation.
