Data Race 30-1002 Rally Synchronous 9600 BPS Modem V.29 V.22 Dual Channel TDM

Data Race 30-1002 Rally Synchronous 9600 BPS Modem V.29 V.22 Dual Channel TDM

The Data Race 30-1002 is a desktop synchronous modem from Data Race's Rally product line, designed for 9600 BPS synchronous data communication over leased telephone lines. It supports the V.29 modulation standard and provides two DB25 serial ports on the rear panel: Channel A (Primary) for the main DTE data connection and Channel B (TDM Only) for time-division multiplexing configurations. The front panel carries six LED indicators — TX, RX, DSR, DCD, SQ, and TEST — for real-time line and signal monitoring.

Applications

The Data Race Rally series was designed for point-to-point and multipoint synchronous data communications over dedicated leased telephone lines, primarily in business and enterprise environments of the late 1980s and early 1990s. V.29 synchronous modems at 9600 BPS were widely used for connecting remote terminals, mainframe front-end processors, and early WAN links at a time when leased-line modems were the standard infrastructure for private wide-area data networks. The dual-channel design with TDM support on Channel B made the Rally series suited to multiplexed leased-line applications where multiple data streams shared a single physical line. Today these units are sought by collectors of vintage telecom equipment and by operators maintaining legacy synchronous serial networks or test environments that require period-accurate hardware.
