IO Extender

Extend your IO Expander serial communication distances up to 4000 feet.

Extend your serial communications distances using standard RJ45 Cat5 network wiring, using only 2 mA for each converter.  The IO Extender requires a pair to work; Sender and Receiver.

To obtain the maximum possible cable length and lowest signal loss it is recommended that the RJ45 wiring follow the TIA/EIA T568A straight through network wiring standard.
