A versatile, miniature communication module with connector jacks for three XR440 Data Loggers and one jack for a Modem or Wireless Data Link.
With one M31, up to three XR440 Data Loggers can be networked together. Up to 254 Data Loggers can be networked using additional M31 Multiplexers. Each additional M31 added to the network supports two additional XR440 Data Loggers. Pocket Logger Software provides full support for network communication.
The M31 is powered by a long-life lithium cell. Estimated battery life is more than 3 years under average use (3 full memory uploads per day).
Where the M31 is not required:
1) Multiple XR440's connected to a single computer using an IC209 Cable and USB-A Adapter for each XR440 does not require the M31 Multiplexer.
2) A single XR440 connected to a dial-up modem does not require the M31 Multiplexer.
