Wiegand Interface Module
Mounting and Wiring
The following are the provisions for the wiring connections on the
LMSC1000 reader system.
• Take special precautions to protect the system's components by locating
them in a weatherproof enclosure (sold separately).
• In the weatherproof enclosure, provide a properly protected 115VAC
power outlet for powering the reader through the provided power supply.
• Once an appropriate weatherproof enclosure with power outlet has been
installed, route the reader cable so that it safely enters the enclosure and
maintains the enclosure's weatherproof capabilities.
• Route Wiegand Data 0, Data 1, and Common from S2W Wiegand
Interface to the access control panel so that it safely exits the enclosure
and maintains the enclosure's weatherproof capabilities.
• AC must be run in a separate conduit.
• Maximum cable distance between Reader and S2W Wiegand Interface
is 19 feet (5.8 m).
• Maximum cable distance between S2W Wiegand Module Interface and
access control system is 350 ft (107 m) with 18 AWG wire.
• Maximum cable distance between the relay control of the S2W and an
external visual/audible device is 98.5 ft.
Arming Loop Input (Optional)
For applications where multiple RFID readers will be in close proximity this
feature can be used to turn on the reader fi eld ONLY when the loop senses
the presence of a vehicle.
When switch 5 is turned on, the Wiegand board sends a command to the
antenna to turn off the reader fi eld until a vehicle presence is detected.

Reader LEDs
The LEDs on the front of the LMSC1000 Reader will illuminate red when
powered. Blinking blue LEDs indicate an RFID tag is being read.
Dry Contact Relay Output
For applications where RFID tag holders want an external visual or audible
notifi cation that the reader processed their tag. The relay contacts change
state for 2 seconds with every valid Wiegand output, if time delay is enabled
the relay will only pulse once during the selected period.
