Figure 3-13. CPU Connector Pin-Outs for RS-232 Mode
To assist in properly connecting the serial ports to either a computer or a modem,
there are activity indicators just above the RS-232 port. Once a cable is
connected between the analyzer and a computer or modem, both the red and
green LEDs should be on.
If the lights are not lit, use the small switch on the rear panel to switch it
between DTE and DCE modes
If both LEDs are still not illuminated, make sure the cable is properly
constructed.
