Pilot Lite Fails to Communicate with Installed Modules
Confirm that the following items are not the reason for the
communication failure:
•
Proper module slot has not been specified (
+
Pilot Lite is not
communicating with the appropriate slot). See your
FR6802
+
Frame Installation and Operation Manual
for more information on
slot identification.
•
COM port is used elsewhere (Check that the correct COM port is
configured in
+
Pilot Lite and that another application is not using
that COM port).
•
Actual frame ID does not match with the two DIP switch settings in
the back of the frame (
+
Pilot Lite is not communicating with the
proper frame). See your FR6802
+
Frame Installation and
Operation Manual
for more information on frame ID switch
settings.
•
Null modem cable is not being used. Between the PC running
+
Pilot Lite and the FR6802
+
frame, there should be a null RS-232
modem cable. At minimum, this requires that pins 2 and 3 are
crossed and 5 to 5 for ground.
•
ICE6800
+
module is installed in the frame (
+
Pilot Lite control is
disabled if an ICE6800
+
module is installed in the frame;
ICE6800
+
modules are used for CCS control).
•
A legacy 6800 series product is in the frame.
+
Pilot Lite cannot
communicate with legacy 6800 series products. They will not be
discovered or controlled by
+
Pilot Lite, although they can be
installed in the FR6802
+
frame and work using card edge controls.
The module must be from the 6800
+
product family.
•
Check that the back module does not have any bent pins, following
this procedure:
a. Unplug the front module.
b. Unscrew and remove the back module.
