Dorado Systems Model 780 Swipe Reader with PIN Pad
With I/NET versions 4.3x and later, the DPU-7910A and -7920 series controllers support
the Dorado 780 reader. This swipe reader adds PIN capabilities to the I/NET system.
While in PIN mode, if a properly encoded card is read, the user must then enter a valid
5-digit PIN before gaining access into the controlled area.
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.
Connecting the Dorado 780 Reader
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.
Note:
The wire colors specified in the following steps refer to the wires from the reader. The actual
wire colors at the DPU will depend on the cabling used for the installation.
1.
On the Dorado 780, set the SW1 DIP switches as follows:
These settings configure the reader to output 26-bit Wiegand-encoded data.
2.
Connect the white (DATA 1) wire from the reader to terminal 3.
3.
Connect the green (DATA 0) wire from the reader to terminal 5.
4.
Connect the brown (CONTROL A) wire from the reader to terminal 6.
5.
Connect the yellow (CONTROL B) wire from the reader to terminal 7.
6.
Connect the red (+12 VDC) wire from the reader to an ex12 VDC linear
power supply.
7.
Splice the GROUND wire from the external power supply to the black (GROUND)
wire from the reader.
8.
Connect the black (GROUND) wire from the reader to terminal 8.
