Data communication
Sends read bar code data from the BL-180 to the PC.
Command communication
Changes the BL-180’s settings by sending a command from the PC to the BL-
180.
All communication is performed using ASCII codes.

The following communication parameters are the default settings for the BL-180:
Baud rate: 9600 bps

Set the PC according to the above settings before attempting communication.
The BL-180 is set, temporarily, to the default settings for 5 seconds after the pow-
er switch is turned on.
When the current settings of BL-180 is not certain, send the command “SSET”
and a [CR] to the BL-180 from your PC with 5 seconds after power-up. This caus-

eter Setting Commands” on page 52. For information on changing the above
