Description

The Asynchronous Line Driver (ALD-19.2) utilizes state of the art digital CMOS technology to provide a feature filled product at a very affordable price. The ALD-19.2 transmits and receives data bi-directional at data rates up to 19.2kbps. The unit is designed for asynchronous Point-to-Point operation.

The ALD-19.2 utilizes a microprocessor to pass control signals bi-directionally independent of data or carrier operation.

The ALD-19.2 is configured as a DCE interface. Control signals for RTS and DTR are passed as in-band flow control. This flow control is full duplex and control signals are transferred simultaneously in both directions.

The ALD-19.2 is switch selectable for data rate and asynchronous data format. The unit supports 7, 8 or 9 bit data and is capable of transmission rates at 9.6k or 19.2kbps.

Applications that benefit from the ALD-19.2 are computer to remote printer applications or multiplexer to remote DTE connection. The ALD-19.2 is very popular in the retail industry for remote thermal printers.

Utilizing new 1998 technology has allowed the ALD-19.2 to operate without AC power. The unit has the ability to operate with only one control signal being active.

The ALD-19.2 is housed in a sturdy metal enclosure and has a three year warranty and a 24 hour turnaround on warranty repairs.
