Proximity Readers Installation Guide
40 CSI Readers
8. Connect the cable shield using one of the following methods:
✧
DPU-7920 connection – When connecting to a DPU-7920, connect the shield
directly to a good earth ground.
✧
DPU-7910A connection through a breakout box – When connecting to a
breakout box, connect the shield and earth ground to terminal 2.
9. Connect the positive lead of the 12 VDC linear power supply to the red wire
terminal 10, TB2 of the ARE-142.
10. Connect the negative lead of the 12 VDC linear power supply to terminal 8 of the
breakout box or DPU-7920.
Note: Always locate the linear power supply as close to the reader as physically possibly to ensure
maximum read ranges and placement separation.
PIN Pad Proximity Readers
In addition to the CSI proximity readers, I/NET versions 4.3x and later also support the
use of the following third-party readers with the DPU-7910A and DPU-7920 series
controllers:
✦
Motorola/Indala ARK-501
✦
Hughes ProxPro ™
These readers add PIN capabilities to the I/NET system. While in PIN mode, if a properly
encoded card is passed in proximity to the reader and is successfully read, the user must
then enter a valid 5-digit PIN.
When a card is read, the reader emits a 26-bit or 32-bit Wiegand-encoded stream (refer
to
“Wiegand Data Format” on page 25 for more information). Pressing a keypad digit
causes the reader to emit an 8-bit stream. The first four bits represent the value of the
digit pressed. The second four bits represent the binary bitwise complement of the first
four bits. The DPU firmware will distinguish between the card read 26-/32-bit stream
and the 8-bit digit stream.
Follow the manufacturer’s instructions for physically installing these readers. Electrical
installation instructions for each reader are described below.
Connecting to the DPU-7910A and -7920 Series Controllers
The wires from the reader connect to 24 AWG (0.206 mm
2
), shielded, twisted-pair cable
that goes to the DPU. This cable connects to the DPU in one of the following ways:
✦
When connecting the reader to a DPU-7910A series controller, the cable from the
reader connects to a CSI breakout box. The breakout box then connects to the DPU
reader ports (1A, 2A, 1B, or 2B) using an RJ45 CSI modular reader cable (CBL063).
✦
When connecting the reader to a DPU-7920 series controller, the cable from the
reader can be connected directly to the reader ports (TB3 and TB4) on the DPU.
The pinout for the DPU-7920 reader ports (TB3 and TB4) and the CSI breakout boxes
are the same. Therefore, the installation instructions for either type of connection are the
same.
