IC-150 Short Haul Modem

Ic-150.jpg Use twisted pair to extend your RS-232 data distance to up to 10Km!

The IC-150 Short Haul Modem allows you to connect the RS-232 ports of remote devices for fast and easy file transfers and data sharing. Save on the cost of extra modems by installing a pair of these economical units and connecting them up with twisted pair cable.         lhlo        m n s zmxvzqd

Transfers can take take place over distances of up to 10km using either 4 wire (for Full Duplex) or 2 wire (for Simplex) telephone line. The nonpowered Line Driver facilitates efficient transmission and reception of serial data without requiring an external power source.

The unit drives your data at various speeds up to 19,200 bps over distances up to 800m using 24-gauge
wire (transmitting at 110 bps over distances up to 10km).
This compact unit plug directly into the back of your asynchronous terminal, which saves
the space that a stand alone unit would use, and also eliminates the bulk and cost of a RS-232 interface (which must have a + 12V DC source) and therefore requires no separate outlet or power supply.

It provides 1,500VAC lighting surge protection and excellent noise rejection through
the use of differential circuitry. The unit is switch-selectable for DCE/DTE.
The Line Driver provides asynchronous transmission and operates full duplex over four wires.
At slower speeds, the distance increases.
Transmission performance may vary depending on operating conditions and wire gauge.
