Product Overview

Features
  • Long distance transmission between remotely located communication devices is possible using a 4-wire cable (twisted pair wire).
  • Multiple (up to 256) child stations can be connected to the parent station. (multipoint).
  • The serial interface conforms to V.24 (RS232 asynchronous).
  • Communication speeds up to 115.2 Kbps are supported.
  • Communication status can be monitored by LEDs.
  • Local fold-back test (LDL-mode) and remote fold-back (fold-back at the opposite device, RDL-mode) test functions are available.
  • Robust metal case with DB25 female connector (for RS232), terminal block and modular terminal block on the rear side.　　
  • No other devices can be connected to the unit. Both parent and child devices require this device.
