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 independant 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 tranferred
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.
