The Patton Model 2010 and 2011 async to sync converters let asynchronous DTEs communicate over synchronous analog or digital connections. The Model 2010 supports data rates from 150 bps to 19.2 kbps. The Model 2011 supports data rates from 19.2 to 64 kbps. Both models plug directly into a local async terminal, PC or host and connect that DTE—via RS-232 cable—to a sync modem, mux or CSU/DSU. When the same set-up is installed on the remote end, the local and remote DTEs can communicate over the synchronous link. Drawing power from either the sync or async RS-232 interface, the Model 2010 and 2011 need no AC power or batteries for operation. Model 2010/2011 sync data rates are automatically adjusted to match the sync DCE output rate, so no data rate strapping is necessary. The Model 2010 and 2011 derive clocking externally from the synchronous DCE, and do not limit data block size. Characters may be up to 11 bits long.
