8.3.5 RS 232/RS 422 communication
The code reader sends an S to the interface as a start-up message and to announce that the device is
ready.
The device operates as follows with the factory settings:
• Activation of the reading gate via SWI1. The integrated illumination becomes visible.
• If a code is detected, it is output via the RS 232 interface according to the following protocol.
<STX><Code data><CR><LF>
(9600 baud, 8 data bits, no parity, 1 stop bit)

Configuration via configuration codes
You can make configuration changes with the help of configuration codes (see chapter 17.3).

Activating device functions
You can activate the following device functions via the control buttons on the control panel:
•
TRIG
•
AUTO
•
ADJ
•
TEACH
Connect the code reader to the voltage supply.
Select the desired function via the control buttons on the control panel (see chapter 3.4.2).
TRIG
Trigger function that activates a read process with the configuration stored in the device, e.g., reading gate
control.
AUTO
By activating the
AUTO
function, the following sequence is started:
1. Optimum image setting: The device determines the optimum illumination setting for the given sce
-
nario.
2. Determine code types and number of digits: If codes are found, they are decoded.
3. Decoder table: The contents of the decoder table stored in the device are deleted. The new codes
(code type and number of digits) are stored in the decoder table.
ADJ
Adjustment function for aligning the device.
The read quality is visually displayed as a percentage in the bar graph display. The bar graph display
depicts the average value over the last ten measurements.
TEACH
With activation of the teach function, a present code is taught-in as a reference code.
During the teach event, the reading gate is opened and a code located in the read field is decoded. The
decoded code is stored as a new reference code in the device.
NOTICE
Only activate the
AUTO
function while at a standstill!
Only activate the
AUTO
function if the code is not moving relative to the device.
NOTICE
AUTO
function not for Pharmacode!
The
AUTO
function cannot be used for Pharmacode codes.
NOTICE
Deactivate the
ADJ
function!
You must deactivate the
ADJ
function with the enter button
.
