RAMSAT ROP 25
(Asynchronous RS232 (DB9) to synchronous RS232 (DB25) interface converter)

Interface unit (2 pcs) with builtin transparent optical modems for maximum electrical noise immunity when long cabling is necessary. Input interface is standard async RS232 (DB9 female) with a maximum speed of 115200 baud.
Output is synchronous RS232 (DB25 male) with external clock controlled from connected DCE (MES) with a typical speed of 56k or 64k. The two units are interconnected by dual fibre optic cable of any length
AT command controlled and transfer protocols with very high performance PPP, HDLC or HASC(tm).
