Cuurent owner of TAG 705 & TAG HL 960 display. I'm looking for alternatives to extend the range of the RS-232 connection from the timer to the display. Line drivers are ok if usable and wireless would be great. Cheap but reliable would be even better. Hopefully someone would offer a solution they themsevles have used.

Hi from Germany,
we use wireless transmitters for years now. It works fine up to 300 meters. The sender and receiver are identically parts known as SIEMENS M101 Data. We use the receiver with 12V batterie. There also is an USB-sender which works with the M101 Data, too. The type is SIEMENS M105 Data.
