The M3 Wireless Connector for Starrett PT22938 gages is the link between your Starrett digital caliper or micrometer and the MobileCollect Wireless measurement collection system. Once connected, measurement data transmits wirelessly from the gage to your SPC software — no manual data entry, no transcription errors, no clipboard in between.
This connector attaches directly to your gage’s SPC output port and plugs into a Mini Mobile Module EVO (M3E) transmitter — together, they replace the standard Starrett PT22938 SPC cable with a compact wireless setup. Each reading transmits wirelessly from the Mini Mobile Module EVO to a MobileCollect Base receiver connected to your PC or data collection workstation.
This connector is designed for Starrett digital instruments that use the PT22938 SPC data cable, including:

MicroRidge also offers the PT22938 cable/connector for other transmitters in the MobileCollect family:
DC Connector — Starrett PT22938 — For the Command Mobile Module wireless transmitter. Use the Command Mobile Module when you need two-way wireless communication — for example, triggering gage readings across multiple transmitters simultaneously from the MobileCollect Base or your SPC software. This is common on large fixtures or multi-point measurement setups where operators can’t physically press each gage’s data send button.
MobileCollect is a brand-agnostic measurement collection platform — it doesn’t lock you into a single gage manufacturer. Whether your shop floor runs Mitutoyo calipers alongside Mahr micrometers, Starrett indicators, or Fowler height gages, MobileCollect connects them all into a single wireless SPC data network. This connector is one component in that system. To complete the wireless link, pair it with a Mini Mobile Module EVO transmitter (MC-MM-M3-EVO) and a MobileCollect Base Receiver.
This is the M3 variant of this cable. It uses a 2×3, 6-pin connector that plugs into the Mini Mobile Module transmitter.
Transmitter compatibility: This M3 cable is fully compatible with both the current Mini Mobile Module EVO M3E transmitter and the retired M3 transmitter. No adapter, firmware change, or configuration required — it plugs directly into either.
This Cable Supports:
See the Mini Mobile Module EVO Connector Compatibility Guide for photos of all four connector and transmitter combinations, including how M3 and M3E cables seat on each transmitter generation.
This cable supports TriggerSync. TriggerSync is a measurement mode where a reading is triggered from the MobileCollect Base Receiver or directly from your SPC application, without a manual button press at the gage. TriggerSync will enable automated data collection across all of your digital gages. This feature is currently under development and scheduled for release in Q3 2026.
