Appendix B: Modem Settings and Cables
Null Modem Cross Cable
Sometimes you might want to connect a device other than a modem to the SC III’s modem
port. You first must find out whether that device is configured as Data Terminal Equipment
(DTE) or Data Communications Equipment (DCE).
A DCE is a device that looks like a modem and the straight cable shown above should be used
with it. If the device is a DTE—that is, it looks like a terminal—then the cable below should
work. A null modem cross cable with male DB-25 to male DB-25 is part number C05039. A
null modem cross cable with male DB-25 to female DB-9 is part number C05928.
