Connecting a Serial Cable for SMDR SMDR (Station Message Detail Recording) can be output from the DX-80 system for use with serial printers of collection in call accounting devices. Connection of the SMDR device to the DX-80 is accomplished through the serial data port on the CPM labeled “SMDR.” Connection to serial printers may require customization of the serial cable used to make the connection. CPM“SMDR” serial port connector (straight- (Dedicated means that this AC outlet has no other equipment connected on this circuit breaker. Whenever a call accounting system (third-party device) is deployed, connection is often no more complicated than using a straight-through, 9-pin, female to male, serial cable. (Use Radio Shack model 26117B for good results.) Connection to the PC/call accounting system is made via an available 9-pin serial port connector that is designated as COM1 or COM2 in the PC configuration. Once the cable is linked between the collection device and the DX-80 CPM-SMDR port, the collection device must be programmed for compatible link protocol (baud rate). At default the SMDR port baud rate is set at 9600 bps.
