RS-232 V2 Mobile Module
RS-232 is a long-established reliable serial communication standard that sends data one bit at a time over a direct connection between two devices (typically a DTE and DCE). To communicate reliably, both sides must use the same COM settings—most importantly baud rate (speed), along with data bits, parity, and stop bits. In traditional RS-232 systems, the link is wired using common connectors such as a DB9 or instrument-specific cables, which makes it dependable but can limit mobility and create cable-management challenges on the shop floor.
RS-232 serial communication is here to stay because it’s proven, simple, and extremely reliable in real-world industrial environments. Its point-to-point, low-overhead design is robust against many of the compatibility and network issues that can affect more complex interfaces, and it continues to be widely supported across instruments, controllers, and software. For many data collection and automation tasks, RS-232 remains a dependable “just works” standard that delivers consistent results year after year.
The MobileCollect RS-232 V2 Mobile Module is a purpose-built wireless transmitter that enables true wireless RS-232 communication with native serial devices—without replacing proven equipment. Many RS-232 instruments output data through a DB9 connector, and RS-232 signal levels can range up to approximately ±15 V; the RS-232 Mobile Module is designed with onboard circuitry to safely handle these higher voltage levels. In addition to DB9, MicroRidge offers multiple cable and connector options to support other common RS-232 connection styles used by gages and industrial devices.
Designed for flexible RS-232 data collection, the RS-232 Mobile Module can be configured to work with a wide range of serial-output gages, scales, DROs, and other devices. Using the MobileCollect setup programs, you can set the required serial COM parameters (baud rate, data bits, parity, stop bits), assign serial commands to the read switch, and apply basic data parsing so only the measurement you need is transmitted—helping streamline automation, improve traceability, and reduce manual data entry.
Putting the RS-232 Mobile Module is setup mode is required to access the configuration menus. To place an RS-232 Module in setup mode and initiate a pairing/action request, follow the sequence of button presses below.
Setup Mode:
Red and Green LEDs will Blink 5x then flash rapidly = Setup Mode (~60 sec)
Pairing/Action Request:



Configuring the RS-232 Mobile Module with MobileCollect Xpress Setup is a straightforward way to bring reliable, serial-output devices into a modern wireless data-collection workflow. Once you’ve set the correct communication parameters, verified clean data output, and confirmed the readings land properly in your host software, you’re ready to streamline collection, reduce manual entry, and improve traceability on the shop floor.
