Modem Qlink-1000
Discontinued, recommended replacement is: Qlink-3000
 |
Features:
|
The QLink-1000 family of short range modems provides mid-speed data access over single-pair copper wires. It can transmit data with rates up to 1152 kbps (without a repeater) for up to 5.2 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 data port operate in synchronous mode only. The data rate is from 64 to 1152 kbps.
The QLink-1000 family contains also the model with Ethernet interface.
The modem has an upgradeable firmware. The upgrading istructions are available here.
