description

Models 485OT9L and 485OTLED are our top-of-the-line converters with both isolation and surge protection, enclosed terminal blocks for tamper resistance and dip switches for configuration. Isolated power and ground generated internally. No power is drawn from the host RS-232 port. LEDs indicate data traffic. Only RS-232 side requires a power supply.

Model 485OI9TB is a basic isolated converter. The RS-232 side draws power from the RS-232 handshake lines of the connected PC. At least one handshake line must be asserted (high) to power the converter. If high handshake lines aren’t available, model 485OT9L is recommended. The RS-422/485 side is powered by an external power supply.

Model 485LDRC9 is a DIN Rail mount, wide temp version of the 485OT9L.
