Chapter 1: Installing the Emulation Probe
Solving Serial Communication Problems
settings as follows:
When you are connected, hit the Enter key. You should get a prompt
back. If nothing echos back, check the switch settings on the emulation
probe.
If the switches are in the correct position and you still do not get
a prompt when you hit return, try turning OFF the power to the
emulation probe and turning it ON again.
If you still don't get a prompt, make sure the RS-232 cable is
connected to the correct port on your PC, and that the cable is
appropriate for connecting the PC to a DCE device.
With certain RS-232 cards, connecting to an RS-232 port where the
emulation probe is turned OFF (or is not connected) will hang the PC.
The only way to get control back is to reboot the PC. Therefore, we
recommend that you always turn ON the emulation probe before
attempting to connect via RS-232.
