Connecting A Serial Cable For Smdr; Power-Up Initialization - Comdial DX-80 Installation & Maintenance Manual

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.
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 26-117B
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.)

Serial Cable Installation Procedure
1. Remove the KSU cover (four screws at each corner) of KSU1.
2. Connect grounded wrist strap to a suitable earth ground. (If a grounded wrist strap is not available, bleed
any static charge from your body before touching circuit modules by touching the gold-painted surface of the
inside of the KSU cabinet. If the KSU is properly grounded this will momentarily discharge static electricity
from your body. NOTE: A GROUNDED WRIST STRAP IS THE BEST METHOD OF ASSURING THAT
STATIC ELECTRICITY DOES NOT DAMAGE CIRCUIT MODULES.)
3. Locate the CPM and "SMDR" serial port on the CPM.
4. Connect the male end of the 9-pin serial cable into this SMDR port.
5. Connect the other end (female) of the 9-pin serial cable to the PC/collection device serial port.
6. Replace the KSU cover.

Power-up Initialization

Proper operation of the DX-80 system requires that the system be initialized at the time of start up. The installation
of the DX-80 is complete only when this critical operation is performed. Occasionally it may be required to
perform this initialization process after the original installation, but this is rare.
Initialization causes the operational customer database to be established and organized for system operation and
future updating. At the time this procedure is complete the default database contents are loaded into operational
memory. The system is ready to run on this database configuration. Customized changes may be made to this
database according to the allowable program settings for the various features.
Initialization Procedure
1. System power must be OFF.
2. Remove the KSU cover (four screws at each corner) of KSU1.
3. Connect grounded wrist strap to a suitable earth ground. (If a grounded wrist strap is not available, bleed
any static charge from your body before touching circuit modules by touching the gold-painted surface of the
