The Sine Systems model MA-1 Modem Adapter is for use with the RFC-1/B Remote Facilities Controller. It consists of a small PC board which connects to the rear edge of the RFC-1 board with a jumper connector. A larger case is included to house the board assembly and a new rack panel that provides access to the new I/O is included.
The MA-1 adapter can be used to allow remote computer access or remote printing. In the latter case, several sites can share the same off-site printer. The MA-1 can be used to allow remote control and telemetry checking using a personal computer. Facilities control software can be scripted quickly using a communications package like Procomm Plus or Telix. (Click here for more information.) Using the RFC-1/B in the serial (modem) mode does not prevent the use of the voice (DTMF) mode.
RFC-1/B software version 4.00 or later is required to operate the MA-1 Modem Adapter. A software upgrade kit is available from Sine Systems as model SU-5. The upgrade includes a new microprocessor, a new speech chip and programming and installation instructions.
Demonstration
Sine Systems maintains a demo transmitter site with an RFC-1 that works in both voice a data mode.
