Connecting the I/DISC Reader and the ESSEX PIN Pad
When using a DPU-7920 series controller, I/NET versions 4.3x and later allow you to
connect both an I/DISC reader and an ESSEX PIN pad to the DPU. In this case, the
I/DISC reader connects to the AUX input on the DPU and the PIN pad connects to the
DPU’s reader inputs. The ESSEX PIN pad provides a red LED and green LED; therefore,
the LED on the I/DISC reader is not used.
You have two wiring options for this configuration as follows:
✦
Use 24 AWG (0.206 mm
2
), shielded, twisted-pair cable (at least 8 conductors) to
connect the reader and PIN pad to TB3 or TB4 on the DPU.
✦
Use two CSI breakout boxes (one at the reader/PIN pad and one at the DPU) and
CSI modular reader cable (CBL063, CBL064, CBL065, or CBL066) connected to
each breakout box.
The pinout for the DPU (TB3 and TB4) and the CSI breakout boxes are the same. There-
fore, the following installation instructions apply to either wiring option.
1.
Connect the grey or white (DATA) wire from the I/DISC reader to terminal 2 on
the breakout box or DPU.
2.
Connect the following wires to terminal 8 on the breakout box or DPU:
✧
Black (GROUND) wire from the I/DISC reader.
✧
Black (GROUND) wire from the PIN pad.
✧
Yellow (ADDRESS 1) wire from the PIN pad.
✧
Violet (ADDRESS 2) wire from the PIN pad.
✧
Orange (ADDRESS 4) wire from the PIN pad.
3.
Connect the red (+12 VDC) wire from the PIN pad to terminal 1 on the breakout
box or DPU.
