Problems Transmitting Data Through the Serial Port

If you are having problems sending or receiving data through the

integrated serial port on the CK30, check these possible

problems:

• Make sure the CK30 is connected to the PC, host computer,

or RS-232 serial device using the appropriate cable adapter

and null modem cable.

• If the CK30 is in a communications dock, make sure that the

communications dock is connected to the serial device using

the appropriate cable.

• You cannot use the decoded serial adapter or AA2 to connect

to any device other than a decoded scanner. The CK30 auto-

detects the serial adapter or AA2, and the scanner software

makes the COM port unavailable. Instead, use the AA3 to

connect a device like a printer to the CK30. The AA3

requires an external power source.

For more information on using the serial port, see “Configuring

Serial Communications” on page 46.

Problems While Scanning Bar Codes

Problem Solution

You cannot see a red beam of light

from the scanner when you press the

Scan button and aim the scanner at a

bar code label.

Make sure that you are using a supported

scanner. For details, see “Attaching a Tethered

Scanner” on page 26 or “Attaching a Scanner to

the Serial Port” on page 28.

If you are using a supported scanner, there are

two possible problems:

• You may be too far away from the bar code

label. Try moving closer to the bar code label

and scan it again.

• You may be scanning the bar code label

“straight on.” Change the scanning angle and

try again.

You can test the effective range of the scanner.

Move within 2 feet of a wall and test the scanner.

You need to be within the scanning range to scan

bar code labels. For help scanning bar codes, see

“Scanning Bar Codes” on page 22.
