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 MX3X is already in a powered docking cradle cabled to a PC, remove and reinsert the

MX3X into the powered cradle.

If the MX3X is connected to a PC by a cable, disconnect the cable from the MX3X and reconnect

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.
