4 In the Connect Using field, ensure that the com port matches the port on your
PC to which you connected the Null Modem cable, and then click OK.
This
action opens the COMx Properties dialog box.
5 Verify that the settings match those shown in the example above, and then
click OK.
If your port settings are configured correctly, you will return to the
HyperTerminal window.
6 In the HyperTerminal window, press [?]. This action opens the module’s
Configuration/Debug menu.
5.2.1 Troubleshooting AFC Manager Connection Problems
If AFC Manager has trouble making a connection to the AFC’s Primary Slave:
1
Check your cabling. You must connect a null-modem cable between the
COM port on your PC and the serial port on the module.
2 Connect to the module’s Configuration/Debug port if possible. If you try to
connect to another of the module’s ports, the AFC’s configuration may have
the Primary Slave hidden at that port. At the Configuration/Debug port the
Primary Slave is always visible.
3 Double-check your communications settings via Communications / Local
Port Settings.
You must set up your COM port to match the settings of the
AFC’s port. By default the AFC sets up its Configuration/Debug port as: Slave
address 244, 9600 baud, no parity, 8 data bits, 1 stop bit, RTU mode; so use
those settings unless the AFC’s default configuration has been changed. Be
sure that you are selecting the correct COM port on your PC, especially if you
are using a USB serial adapter as those adapters may be assigned to
different COM ports at different times.
4 Ensure that the COM port on your PC is not in use by another application,
such as HyperTerminal. If the port is held by another application, then AFC
Manager will not be able to use it.
