Product Overview
A practical path for bringing installed serial equipment into modern industrial data networks.
The DT-9000 is a passive interface converter for linking an RS232 host to RS485 serial equipment. The official legacy source lists compatibility with EIA/TIA RS-232C and RS485 interfaces.
It operates with asynchronous half-duplex differential transmission and supports 300 to 115200 bps. The source specifies less than 1200 metres on the RS485 side and within 15 metres on the RS232 side.
