RS-232 Asynchronous Interface
The Aprisa SR+ radio’s ITU-T V.24 compliant RS-232 interface is configured as a Cisco® pinout DCE. The
interface terminates to a DTE using a straight-through cable or to a DCE with a crossover cable (null modem).
The interface uses two handshaking control lines between the DTE and the DCE.
