Setting Up the BayStack Instant Internet 100-S Unit

   

Appendix B
Adapter cable pinout diagrams

This appendix describes the pinout settings for the modem and null modem 
adapter cables.

Remote access adapter cables

If you want to connect a PC or dial-up modem directly to your Instant Internet 
100-S unit to configure the unit using remote access commands (out-of-band 
management), you must provide the connection cable. These are standard cables. 
You can have a cable made according to the pinout diagrams in this appendix or 
you can purchase the cable from any computer supply store.

For information on configuring your unit remotely, refer to Reference for the 
BayStack Instant Internet Remote Access Commands Version 7.11
.

Null modem adapter (PC-to-PC) cable

Figure 14

 shows the pinout settings for a null modem adapter cable (also referred 

to as a pc-to-pc file transfer cable). This serial cable must have two DB-9 female 
connectors.

Use a null modem cable to connect a PC to the Instant Internet unit’s AUX port 
for out-of-band management.
