RAD MME Replaces Two Sync Modems


  • MME is a miniature modem eliminator, which replaces two synchronous modems by permitting direct port-to-port connection.
  • MME is the smallest modem eliminator available in the market. It requires no AC supply connection, using the ultra-low power from the standard RS-232/V.24 data and control signals.
  • MME generates the Receive and Transmit clocks required for proper operation of the two synchronous DTEs, as well as all the control signals necessary to emulate dial-up or dedicated service.
  • The delay between Request to Send and Clear to Send can be independently set on either port, for 0, 6.6 or 53 msec.
  • The Data Carrier Detect signal can either be set constantly to ON, or used as a port-to-port "handshaking" signal where RTS on one port is converted to DCD on the other port.
  • Physical connection between MME and its associated terminal and computer is via 25-pin RS-232 connectors, either two male or two female.
