Teach-In Mode:
Dynamic/Static with Pharmacode/Static without
Pharmacode
The “teach-in” feature allows a user to initiate a simple sequence to have
the scanner learn the actual bar code within its scan line, eliminating the
need to interface to a computer to re-enter the new match code value.
There are two versions of the teach mode, Dynamic and Static. The Static
mode can be selected with or without the Pharmacode symbology. Also, if
the Static teach-in mode is selected the user can have the scanner coun-
ters reset automatically after the teach cycle is complete.
If the Dynamic teach-in mode is selected it activates the Dynamic mode
and the user needs to use the following procedure:
Connect the scanner’s input 2 line to a 24 V DC source during the power up cycle of the scanner. This places the scanner into
the Teach mode of operation. To teach-in a new match code value, disconnect the input 2 line from the source voltage and then
trigger the scanner to take a reading (the bar code to be read must be of a symbology that is already activated in the scanner).
The scanner will read the bar code and place the value into the match code 1 position. The final step is to re-connect the input 2
line and the source line; this will save the new value to permanent memory of the scanner and place the scanner into the ready
state. The Dynamic teach-in has the following prerequisites:
1. Scanner needs to be powered up with the input 2 line connected to a 24 V DC source
2. The symbologies to be learned need to be activated within the scanner prior to the teach process
3. The scanner needs to be triggered
4. This procedure is only valid for Match Code 1 of the scanner
If the “Static” teach-in mode is selected, it is activated and the following procedure applies:
Connect the scanner’s input 2 line to a 24 V DC source during the power up cycle of the scanner. This places the scanner into
the Teach mode of operation. To teach-in a new match code value, disconnect the input 2 line from the source voltage. The scan-
ner will activate all symbologies, read the bar code, deactivate all other symbologies, and place the value into the match code 1
position. The final step is to re-connect the input 2 line and the source; this will save the new value to permanent memory of the
scanner and place the scanner into the ready state. Static teach-in enhancement has reduced the number of earlier mentioned
prerequisites:
1. The symbology of the bar code to be learned does not need to be activated prior to the teach mode process.
2. The scanner self-triggers, eliminating the need for an external trigger to activate the scan line.
3. If reading a pharmacode bar code, it needs to be at least 5 bars long.
4. If reading an Interleaved 2 of 5 bar code, it needs to be at least 4 characters in length.
An alternative method is to use the Host Command to activate the teach-in procedure (see below).
<STX>2TE<ETX> - activates the teach-in process
<STX>2TS<ETX> - deactivates teach-in process and stores the read value
Device ID Number
(1-99)
Device ID numbers enable the user to differentiate between several reading stations. A scanner’s ID number is sent to the host
with the data string and output as part of the separator. See Data String: Separator”. Settings are adjustable in steps of a factor of
one; general applications use 01 to 99; The CLX 200 network controller uses 1 to 31. An explanation of ID number assignments
in the master/slave mode follows:
