§
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's 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.

2.7 Cable Connections
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. The opposite end of the drain line should be connected to the negative
terminal and the frame connection of the power supply.
CAUTION!
The shunt jumper P2 is not installed as the factory default for +24VDC operation. If the jumper is in the
+12 VDC position and +21 to +28.5 VDC is applied, circuit damage can result.

Note
On TB2, pins 1, 2 and 7 have multiple purposes, depending on the interface that the Reader is
configured for. In the table above, the first description is for Wiegand, the second for Clock and Data,
the third for RS232, and the fourth is for RS422.
