Vanguard 7300 Installation 

3-35

All cabling for the Serial card is done at the rear of the chassis on the 8-port rear 
panel shown in Figure 3-28. The eight ports support up to eight channels of serial 
data for WAN networking and telecommunications applications. 

Each Serial card port can be software configured for synchronous serial 
communication protocol. Software-configurable baud rates range from 1.2Kbps to 
8Mbps. For software configuration procedures, refer to Chapter 4, Operating Your 
Vanguard 7300.

Due to the high traffic density of this board, the following interface-specific cables 
are required with these characteristics:

• Serial card cables have a fixed length of seven feet

• Separate Data Terminal Equipment (DTE) and Data Communications 

Equipment (DCE) cables are required because DTE/DCE operating mode is 
determined by the physical cable characteristics

This table lists the cables available for use with the Serial card:

For cable details, see Appendix B, Vanguard 7300 Cable Connectors and 
Pinouts.
