Installing a Serial Cable

You will need the following type of serial cable.

■For a Macintosh computer, you will need a 25-pin male to mini DIN 8-pin male serial cable. Refer to the information enclosed in your 3C882 ISDN modem package to order a free cable. If you are providing your own serial cable, ensure that it meets the pin specifications provided in Appendix C.

■For a PC, you will need the 25-pin male to 9-pin female serial cable that was provided. For PCs with a 25-pin serial port connector, you will need to purchase a standard 9-pin to 25-pin adapter.

To install the 3C882 ISDN modem serial cable:

1Insert the 25-pin male end of a serial signal cable into the RS-232 serial port on the 3C882 ISDN modem’s back panel and tighten the connector screws, as shown in Figure 2-4.
