Troubleshooting
ActiveSync on the host says that a device is trying to connect, but it cannot
identify it
One or more control lines are not connected. This is usually a cable problem, but on a laptop or
other device, it may indicate a bad serial port.
ActiveSync indicator on the host (disc in the toolbar tray) turns green and spins
as soon as you connect the cable, before clicking the Connect icon (or
REPLLOG.EXE in the Windows directory).
One or more control lines are tied together incorrectly. This is usually a cable problem, but on a
laptop or other device, it may indicate a bad serial port.
ActiveSync indicator on the host turns green and spins, but connection never
occurs
Baud rate of connection is not supported or detected by host.
-or-
Incorrect or broken data lines in cable.
ActiveSync indicator on the host remains gray
The host doesn't know you are trying to connect. May mean a bad cable, with no control lines
connected, or an incompatible baud rate. Try the connection again, with a known-good cable.
Testing connection with a terminal program, or a serial port monitor:
You can use HyperTerminal or some other terminal emulator program to do a rough test of
ActiveSync. Set the terminal emulator to 8 bits, no parity, 1 stop bits, and the same baud rate as the
connection on the CE device. After double-clicking REPLLOG.EXE on the CE device, the word
"CLIENT" appears on the display in ASCII format. When using a serial port monitor, you see the
host echo "CLIENT", followed by "SERVER". After this point, the data stream becomes straight
(binary) PPP.
Special issues with USB
If USB connects correctly, but the computer goes into suspend (or the red power button is tapped),
the computer will forget its USB address. It will not check again until after the USB cable is
removed and 15-30 seconds have expired. Reconnect.
The LXE-supplied version of ActiveSync will identify the device during the initial setup detection
(New Hardware Found) as “LXE MX3-CE”, but other versions of ActiveSync will only identify it
as a Microsoft ActiveSync device.
