LDM2485B

Dataforth's Model LDM2485A & LDM2485B high speed, RS-232 to RS-485 interface converters can turn your PC, terminal or other RS-232 device into an RS-485 workstation. Operating over 2 to 4 wires, at data rates up to 115.2 kbps, Models LDM2485A & LDM2485B let your RS-232 machine talk with up to 50 addressable devices in a multipoint polling environment. Since multipoint environments can be difficult to work with, these products have five separate configuration parameters (carrier control, RTS/CTS delay,receive impedance, transmit-off impedance and echo) that allow you to fine tune the converters to your particular application. And to keep your application up and running, both models have built in surge protection. The Model LDM2485A has a DB-25 connector for RS-232 environments, while the Model LDM2485B has a DB-9 connector for EIA-574. Both models have several options for twisted pair connection.
