5. The
Manual Call
menu now appears, from the
Direct Cable Port
dropdown list pick
the COM port that you will be using.
A note about COM port choice:
In the example above of a Laptop, you can see 3 COM ports listed, the numbers
and descriptions vary from PC to PC but to summarise the types:-
RIM Virtual Serial Port
(e.g. COM1:) should be ignored as Radwin will not
communicate via these types of ports. These often have high COM numbers
(above 10).
USB Serial Port
(e.g. COM2:) is a genuine COM port that can be used with
Radwin and is usually the USB Reader cable.
USB to Serial Bridge
(e.g. COM4:) is also a genuine COM port that can be
used and is generally a USB to Serial adaptor cable.
If you are using a Desktop computer or a Laptop with a docking station, you may
also see a
Communications Port
. This is also a valid choice for your
Direct Cable
Port
, however there is usually more than one so check the physical indication by the
socket on the back of the computer
.
Tip:
If you are using a USB connection, you can check you have the right one as
follows:-
i.
Look down the list and note each COM number that is not empty.
ii.
Click <<Cancel>> to close the
System Configuration
menu.
iii.
Remove the USB plug from the PC.
iv.
Repeat steps 3 to 5 above and look for the one that has disappeared. This is
the COM port you need to select in step 5.
v.
Click <<Cancel>> to close the
System Configuration
menu again.
vi.
Reinsert the USB cable
IN THE SAME PORT AS BEFORE
and repeat steps
3 to 5, selecting the COM port noted in step iv above.
