TROUBLESHOOTING
Symptom Possible Cause(s) Solution
Aux Port Operation With Any Interface
The secondary scanner is
not functioning.
Refer to the user’s guide provided with the secondary scanner.
The secondary scanner
cable may not be connected
to the proper port on the
StratosH.
Ensure that the secondary scanner is connected to the
StratosH’s com port marked “Aux” port.
* The StratosH must be configured to enable the auxiliary
port.
The secondary scanner
powers up but data is not
relayed to the host.
The auxiliary com port may
not be operating properly.
The auxiliary input port’s data format must match the main
output format of the secondary scanner.
* Refer to the MS2xxx Stratos Series Configuration Addendum (MLPN 00-02034x) under Scanner Configuration Bar
Codes: Auxiliary Port, Quick Start for a Secondary Metrologic Scanner.
RS232 DEMONSTRATION PROGRAM
If an RS232 scanner is not communicating with your IBM compatible PC, key in the following BASIC program to test that
the communication port and scanner are working. This program is for demonstration purposes only. It is only intended to
prove that cabling is correct, the com port is working, and the scanner is working. If the bar code data displays on the
screen while using this program, it only demonstrates that the hardware interface and scanner are working. At this point,
investigate whether the application software and the scanner configuration match. If the application does not support
RS232 scanners, a software wedge program that will take RS232 data and place it into a keyboard buffer may be needed.
This program tells the PC to ignore RTS-CTS, Data Set Ready (DSR) and Data Carrier Detect (DCD) signals. If the
demonstration program works and yours still does not, jumper RTS to CTS and Data Terminal Reading (DTR) to DCD and
DSR on the back of your PC.
