Setting the required parameters is carried out easiest in the 'Service' operating mode. The
operating mode Service provides the following defined operating parameters on the RS 232
interface, no matter how the BCL 8 is configured for standard operation:
• Transmission rate: 9600 baud
• No parity
• 8 data bits
• 1 stop bit
• Prefix: STX
• Postfix: CR, LF
Activate service interface
The service interface can be activated by holding a defined bar code label ("Service", see

Figure 7.1:
While the laser switches on for approx. 1s after power-up, the "Service" label is to be held
up in front of the bar code reader at a suitable read distance. When the device is in service
mode, the status LED flashes orange.
Connection
You can connect a PC or a terminal to the BCL 8 via the serial interface and configure the
BCL 8 through this connection. The connection is made using an RS 232 connection cable
that establishes the RxD, TxD and GND connections between PC and BCL 8.
If the BCL 8 is connected to a connection unit, you can establish the connection in the same
way in front of the connection unit. For the respective pin assignments, please refer to the
data sheet of the connection unit.
