Key Features
Overview
The M-131 adapter bridges the communication gap between modern PCs and Maynuo test equipment, converting TTL signal levels to RS-232 standard. Essential for remote control, automated testing, and data acquisition applications.
All Maynuo electronic loads and programmable power supplies feature TTL-level DB9 ports that require voltage level conversion for PC compatibility. The M-131 includes galvanic isolation to prevent ground loops and protect both instruments during measurement operations.
Compatible with standard serial communication software and includes LED status indicators for real-time TX/RX monitoring. For USB connectivity requirements, consider the Maynuo M-133 USB adapter as an alternative.

Questions and Answers
-
Can I Use the M-131 with USB-to-Serial Adapters?
Maynuo’s manuals describe the M-131 for connection to a PC RS-232 serial port. If your PC has only USB ports, Maynuo offers the M-133 DB9-to-USB cable instead.
-
Does the M-131 Include Galvanic Isolation?
Galvanic isolation is not specified for the M-131. If your setup needs isolation between the instrument and PC, please contact us before ordering.
-
What Software Works with the M-131 Adapter?
Use PC software for your instrument or your own custom applications. M88 series power supplies accept SCPI commands, which you can also send from a standard serial terminal program. M97 series electronic loads use the Modbus protocol.
-
How Long Is the M-131 Cable?
The cable length is not specified. Please contact us if you need the exact length.
-
What Is the M-131 Adapter Used For?
The M-131 converts TTL voltage levels from Maynuo electronic loads and power supplies to RS-232 levels for a PC serial port, so you can control the instrument remotely.
-
Can I Connect My Maynuo Instrument Directly to a PC Without the M-131?
No. The instrument’s DB9 port uses TTL voltage levels, so a standard RS-232 cable to a PC serial port will not work. Use the M-131 (RS-232) or M-133 (USB) level conversion cable.
-
Which Maynuo Instruments Are Compatible with the M-131?
Maynuo M97 series electronic loads and M88 series programmable power supplies with TTL DB9 communication ports work with the M-131 adapter. For other series, such as M98 and M983X, please check the instrument’s manual or contact us.
-
Does the M-131 Require External Power?
No external power supply is listed for the M-131. The instrument’s DB9 port provides +5 V on pin 1.
-
What Communication Speeds Does the M-131 Support?
The baud rate is set on the instrument, not on the adapter. Maynuo’s M88 and M97 manuals list 4800, 9600, 19200 and 38400 bps, with 9600 bps as the shown setting. The PC software must use the same baud rate and address.
