Connect the Wiegand Outputs
Optically-isolated open-collector outputs are provided to meet the
requirements of the AC01 Wiegand specification. These are protected by 5V
transient voltage-suppression diodes.
To connect the Wiegand outputs, perform the following:
1 1 1 1 When using the single Internal antenna of the 6204, connect CH1 (3
wires) of the WIM to the Wiegand panel.
2
2 2
2 If using the External antenna, connect CH2 (3 wires) of the WIM to the
Wiegand panel.
3 3 3 3 Refer to Figure 9 for the standard Wiegand color code as defined in the
AC-01 Wiegand specification.

Connect the 24V Power
To connect 24V power, perform the following:
1
1 1
1 Using the black and red power harness supplied, connect one end of
the black wire to Terminal 1 (
PGND
).
2 2 2 2 Connect one end of the red wire to Terminal 2 (
+24V
) of the
READER/POWER
connector.
3 3 3 3 Connect the remaining end of the red wire to the + output terminal.

Initial Testing
Initial testing is optional, but recommended. The purpose is to verify that
the 24V PSU and Wiegand module power supply are operating correctly.
Perform the following:
1 1 1 1 Ensure that the reader is disconnected from the umbilical cable by
unlocking and removing the connector at the reader end.
2 2 2 2 Apply AC power to the PSU Module.
3 3 3 3 Using a Digital Multimeter (DMM) confirm that the output of the PSU
lies in the range 21.6 to 26.4 VDC

4 4
4 Check that the
PWR LED
on the module is illuminated.
5 5 5 5 Using the DMM, measure the DC voltage between
PGND
and
RFU
on
the
READER/POWER
connector. For correct operation, this should be
between 4.75 and 5.25 VDC.
6 6 6 6 Disconnect the PSU and reconnect the umbilical cord to the reader.
