Repeater configuration
The DNZR-768 requires the following five jumper settings.
• Baud rate
•
Data wires termination for segment 1
•
Data wires termination for segment 2
•
Data wires termination for segment 3
• Data wires termination for segment 4
Baud rate jumper
The DZNR baud rate is set by positioning a jumper across the appropriate speed pins. Fixed
speeds range from 9600 to 76800 bps, or the Auto Baud setting may be used.
The same baud rate must be used for all network segments.
If multiple jumpers are in place or no jumper is in place, the DZNR sets its baud rate to 76800
bps.
Fixed baud rate selection
Place one jumper for the chosen baud rate from 9600 to 76800 bps. The DZNR operates only at
that baud rate. The LED adjacent to the selected speed is illuminated
AUTO
76800
38400
19200
9600
Auto baud rate selection
Place one jumper on the AUTO position. The DZNR attempts to set its baud rate to match the
baud rate of the controller on segment 1. If no device is connected to Segment 1, then the
DZNR sets its baud rate to 76800. The LED adjacent to the detected speed is illuminated.
