Designed & Made in the USA Since 1983
RS-232 interface cable for Mahr Federal gages with the 4-pin female SPC output port. Compatible gage families include Digimar Digital Height Gages, MarCator Digital Indicators, Millimess Digital Comparators, and µMaxum II. Connects the gage’s 4-pin RS-232 output to a DB9 host interface — compatible with WedgeLink AT, WedgeLink SP, MobileCollect RS-232 Remote, and GageWay Pro (Level Converter Cable required for GageWay Pro front channels). When paired with any of the above, measurement data outputs as keystrokes or USB serial — ready for direct input to SPC software or any data collection application.

The Mahr Federal 4346020 RS-232 cable connects the 4-pin serial output port of compatible Mahr Federal instruments to a data collection host — eliminating manual transcription of measurement readings and enabling direct output to SPC software, inspection databases, or any application that accepts RS-232 serial data.
The gage-side connector mates with the 4-pin female SPC output port on the instrument and includes the Mahr Federal Digimatic to RS-232 translator, as shown. The host side terminates in a DB9 male connector, compatible with WedgeLink keyboard wedges, MobileCollect RS-232 Remote wireless transmitters, and GageWay Pro wired interfaces.
The 4346020 cable is compatible with Mahr Federal instruments that use the 4-pin female SPC output port, including but not limited to:
Not sure if your Mahr Federal gage uses the 4-pin connector? Use the MobileCollect Selection Tool to look up your specific model, or contact sales@microridge.com.
Before connecting the cable, verify the gage’s RS-232 communication parameters match your receiving interface. WedgeLink and GageWay Pro both support auto baud rate detection, which simplifies initial setup. For specific RS-232 settings on your instrument, refer to your Mahr Federal documentation or contact Mahr Federal support.
Refer to your WedgeLink or GageWay Pro documentation for host-side comm parameter configuration.
WedgeLink AT / WedgeLink SP — WedgeLink keyboard wedge technology translates the Mahr Federal RS-232 serial output into keystrokes, sending measurement readings directly into Excel, SPC software, or any application that accepts keyboard input — no software integration required. Auto baud rate detection simplifies setup; data parsing handles the native Mahr Federal output format.
MobileCollect RS-232 Remote — For wireless data collection without cable runs between the gage and the collection point, the RS-232 Remote pairs with this cable to transmit measurement readings wirelessly over MobileCollect’s RM2.4 proprietary protocol. 133-foot wireless range, encrypted, and resilient to RF noise common in industrial inspection environments.
GageWay Pro — Connects to the GageWay Pro via the multifunction serial port or the front gage channels (Level Converter Cable GW-LC required for front channels). The GageWay Pro provides USB serial and USB keyboard wedge output alongside its DB9 port, with configurable read modes (single, continuous, TIR) and data parsing for complex instrument output strings.
MicroRidge offers the 4346020 cable/connector for other systems in the MobileCollect and GageWay product families:
M3 Connector — Mahr Federal 4346020 — If you need to take your Mahr Federal gage wireless without a cable run to a host PC, this is the connector you need. It pairs with the Mini Mobile Module EVO (M3E) transmitter, integrating directly into the MobileCollect wireless network. Use the cable on this page for wired connections; use the M3 connector for mobility.
DC Connector — Mahr Federal 4346020 — 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.
OEM SPC Digimatic Cable — Mahr Federal 4346021 — For wired connections to GageWay interfaces using Mahr Federal’s Digimatic-compatible output. Use this cable when connecting to a GageWay Single or GageWay Pro front-panel gage channel without a Level Converter Cable.
OEM SPC RS-232 Cable — Mahr Federal 4346020 (this page) — For wired RS-232 connections to WedgeLink, MobileCollect RS-232 Remote, and GageWay Pro via the multifunction serial port or front channels with a Level Converter Cable.
Q: Is this cable compatible with the original Mahr Federal µMaxum?
— No. The original µMaxum uses a different 7-pin connector. This cable is compatible with the µMaxum II, which uses the standard 4-pin female SPC output port. See the µMaxum gage cable for the original µMaxum.
Q: What is the difference between the 4346020 and the 4346021 cable?
— The 4346020 (this cable) provides RS-232 serial output via DB9, for use with WedgeLink, MobileCollect RS-232 Remote, and GageWay Pro via the multifunction serial port or Level Converter Cable. The 4346021 provides Digimatic-compatible output for direct connection to GageWay Single and GageWay Pro front-panel gage channels without a Level Converter Cable — if your primary use case is a GageWay interface, the 4346021 is typically the simpler setup.
Q: What software can I send measurement data to with this cable?
— Any software application that accepts keyboard input or USB serial data — including SPC programs, Excel, custom inspection databases, and MES systems. On its own, this cable provides RS-232 serial communication via DB9 only. A MicroRidge interface (WedgeLink, GageWay Pro, or MobileCollect RS-232 Remote) is required to convert that signal to USB serial or keystrokes for input to any application on the host.
Q: Do I need to configure baud rate settings on my gage?
— The gage’s RS-232 comm parameters must match the receiving interface. WedgeLink and GageWay Pro both support auto baud rate detection, which simplifies initial setup. Refer to your Mahr Federal documentation for how to access RS-232 settings on your specific instrument.
Q: What if I need a wireless solution instead of a wired cable?
— The M3 Connector — Mahr Federal 4346020 pairs with the Mini Mobile Module EVO to transmit measurement data wirelessly to any MobileCollect Base receiver. 133-foot range, RM2.4 encrypted protocol, no cable to the host PC required.
