About East Coast Datacom, Inc

East Coast Datacom, Inc. is a customer oriented, high technology enterprise which was formed in 1994 to design, manufacture and support Wide Area Network Equipment. We manufacture the broadest line of Network Emulators in the network test equipment market supporting over 18 different interfaces for Serial, Telco and Ethernet.

For Ethernet, the WanRaptor™ Network Emulator allows users to test and stage critical network equipment adding network latency, loss, Jitter and re-ordering impairments. For Serial data and Telco the RDS-PLUS delay simulator is a modular, network link error and delay emulator that provides a realistic simulation of physical network behavior with respect to time delays and bit errors.

We also manufacture an extensive line of legacy network equipment critical to the military, government and Fortune 500 companies. These include data broadcast splitters, digital sharing devices, interface converters and many other network adapters. Our highly respected Sync2IP Converter is a unique solution for Sync data to IP conversion as we support any sync data protocol.

We hope you enjoy our collection of products we present on our web site. Keep in mind we can modify or design a new solution for your unique application.

Features / Benefits

  • Interface - RS-232 and Dedicated 4-Wire
  • Data Rates - Asynchronous 9.6K and 19.2Kpbs
  • Point to Point operation
  • Full Duplex Operation
  • Transmission Range-2000 feet on 24awg wire
  • Transfers Control Signals In-Band
  • No AC Required
  • Built-in Surge Protection


The Async 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.
