ASC 422


This async to sync converter allows Asynchronous RS-232 DTE equipment to communicate over Synchronous RS-530 or RS-422/449 DCE equipment. The product was developed especially for government and secure encrypted Modems utilized by a Gretacoder that has an existing RS-422/V.11 electrical interface.

The ASC-422 Async to Sync Converter is designed to allow RS-232 async terminal equipment to transmit over higher speed V.11 compliant sync modems. The ASC-422 devices are used in pairs, one at each end of the communication link or in multiples as when used in a multi-drop communication link.

The ASC-422 supports async data of 8, 9, 10 and 11 bits, including the start and stop bit. Standard data rates from 1200 to 38.4bps and 3/4 rates of 900 to 28.8bps are supported for synchronous transmission. The ASC-422 automatically adjusts the sync data rate to match the DTE’s output rate, no data rate strapping is required.

Stop bit reduction is provided when the async data rate is faster than the sync data rate, ensuring reliable data communications.

Utilizing new silicon chip technology this device derives its power from both the async and sync interfaces, thus no power supply is required. This equates to savings in your power requirements and with battery backup at your data center.

The ASC-422 is housed in a sturdy metal enclosure and will provide in excess of 100,000 hours of reliable service.
