Troubleshooting ActiveSync
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.
If the MX3-RFID is connected to a PC by the USB cable, disconnect the cable from the mobile
device and connect it again.
Check that the correct connection is selected (Serial or USB “Client” if this is the initial
ActiveSync installation).
See Also: “Cold Boot and Loss of Host Reconnection”.
ActiveSync indicator on the host (disc in the toolbar tray) turns green and spins
as soon as you connect the cable, before tapping 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. Check that the correct connection is
selected (Serial or USB “Client” if this is the initial ActiveSync installation).
-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 emulator 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-tapping 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.
