Attaching an
External Modem
Both the JACE-4 and JACE-5 have one or more DTE serial ports. This means that,
in order to attach a modem (which is a DCE device), you need to use a serial cable
that is pinned straight through.
JACE-5
With the JACE-5 you use a standard serial cable with a DB-9 female connector on
one end, and typically, a DB-25 male connector on the other end. Connect the DB-9
end of the cable to the serial port on the JACE-5 and the DB-25 end to the modem.
