Specifications
Documentation

Modem Qlink-144 Features:
  • Up to 8 km over single copper pair
  • V.35/RS-530/RS-232/X.21/Ethernet data interface
  • Additional RS-232 async data interface
  • Sync data rates from 16 to 144 kbit/sec
  • Async data rates from 1200 to 115200 bit/sec
  • Line protection
  • Configurable by DIP switches or via RS-232 port
  • Upgradeable firmware

The Qlink family of leased line modems provides mid-speed data access over single-pair copper wires. It can transmit data with rates up to 144 kbps (without a repeater) for up to 8 km. Using lower guage copper wire may allow you to attain greater distances.

It can be configured using DIP switches or via RS-232 control port.

The modem has one main data port. The Qlink-144X has additional asynchronous interface, which can be used for control (console), or as extra data port. The main data port supports both synchronous and asynchronous modes. The data rate is: in synchronous mode - from 16 to 144 kbps, in asynchronous mode - from 1200 to 115200 bps.

The Qlink family contains also the model with Ethernet interface.

The modem has an upgradeable firmware. The upgrading istructions are available here.
