RS-485 Repeater
We designed the 485-RPT auto-enabled 2-wire microprocessor
controlled RS485 repeater to provide error free data communications
via an RS485 link. The RS485 drivers are enable controlled
automatically using an on board microprocessor, providing fast
multi-drop capability for a variety of applications using the single
pair RS485 differential signals.
Extend the RS485 beyond the 4,000 feet limitation, or whenever there
is a need to “boost” the RS485 signal.
