LiftMaster K-S2W RFID Wiegand Interface Module
The LiftMaster K-S2W is an RFID Wiegand interface module service kit used with the LiftMaster LMSC1000 long-range RFID vehicle access reader. It acts as the interface point between the RFID reader system and compatible Wiegand access-control equipment.
In an RFID vehicle-access installation, the reader, interface module, credentials, power supply, and access-control panel all need to work together. The K-S2W module supports the data and power interface functions required for the LMSC1000 reader system and helps deliver a usable Wiegand signal to the access controller.
This service kit should not be confused with the LMSC1000 reader, the K-AUMB mounting bracket, vehicle tags, or the access-control panel. Compatibility depends on the reader model, Wiegand format, terminal wiring, power requirements, enclosure location, and site layout.
Common Use Cases
- Replacing a failed or damaged Wiegand interface module in a LiftMaster LMSC1000 RFID system
- Servicing long-range RFID vehicle access installations using Wiegand access-control inputs
- Restoring communication between the LMSC1000 reader and access-control panel
- Supporting RFID access for gated communities, parking facilities, and controlled entrances
- Adjusting reader performance where the module and site setup allow range adjustment
Compatible With
K-S2W is commonly listed for the LiftMaster LMSC1000 long-range RFID reader and compatible Wiegand access-control applications.
- LiftMaster LMSC1000 long-range RFID reader
- Select Wiegand-compatible access-control panels used with the LMSC1000 reader
- Select LiftMaster CAPXL, CAPXM, or other access-control systems with compatible Wiegand inputs when properly configured
- Vehicle access systems using compatible LiftMaster long-range RFID credentials
- Installations where the system manual calls for the S2W or K-S2W Wiegand interface module
Important: Compatibility should be verified by the original part number, model number, production version, and the correct LiftMaster parts diagram before ordering. Similar-looking parts may not fit the same system.
Not Intended For
- RFID readers other than LMSC1000 unless confirmed
- Replacing the LMSC1000 reader, K-AUMB mounting bracket, RFID vehicle tags, or access-control panel
- OSDP-only reader inputs without compatible Wiegand support
- Systems with read-range problems caused by wrong tag type, poor reader aim, interference, or access-panel programming
- High-voltage switching or direct gate operator motor control

Technician Note
Reader range is affected by more than the electronics. Before replacing the module, check tag type, tag placement on the vehicle, reader aiming, bracket position, lane width, power, grounding, and cable condition.
Wiegand wiring should be kept clean and correctly terminated. Confirm data lines, ground, power, and controller input format before powering the system. Incorrect wiring can damage parts or prevent reads from being accepted by the access controller.
Before Ordering, Confirm
- The RFID reader is a LiftMaster LMSC1000 or confirmed compatible system.
- The existing module or manual references K-S2W, K-S2W-1, or S2W Wiegand interface module.
- The access-control panel accepts the required Wiegand format.
- Power, ground, D0, D1, and related terminal wiring are identified before installation.
- Reader mounting, K-AUMB bracket position, and tag placement have been checked.
- The system will be tested with real vehicle credentials after installation.
Professional Advisory
This is an access-control interface module and should be installed by a qualified technician when Wiegand wiring, power, or reader configuration is not clearly understood.
After installation, test reader detection, access-panel event logging, relay/gate activation, credential permissions, and all gate or door safety devices. Do not use RFID access to operate an unsafe gate.
Product Q&A
What is the LiftMaster K-S2W module used for?
K-S2W is a RFID Wiegand interface module service kit used with the LiftMaster LMSC1000 long-range RFID reader.
Is K-S2W the same as K-S2W-1?
K-S2W-1 is commonly listed as a related or also-known-as number. Verify the exact part label and system manual before ordering.
Does this module include the LMSC1000 reader?
No. K-S2W should be treated as the Wiegand interface module service kit. The LMSC1000 reader, tags, mounting bracket, transformer, and access-control panel may be separate unless specified.
What does the module do?
The module supports data and power interface functions for the LMSC1000 RFID reader and helps provide Wiegand communication to compatible access-control equipment.
Can this connect to any access-control panel?
It should be used only with compatible Wiegand access-control equipment and the correct LiftMaster RFID reader. Confirm Wiegand format, power, wiring, and panel inputs before ordering.
Why does read range need adjustment?
The S2W module is associated with reader range adjustment, and the final read range can depend on tag type, vehicle placement, reader aim, mounting location, and site conditions.
