‘Save’ button to save the new settings in order to use them.
The
Bar Code Test field allows the operator to test the operation of the barcode scanner. As a bar code is
swiped by the reader, the scanned value will appear in this field. If upon scanning a bar code, no value appears
in this field, check the wiring and communication settings of the barcode scanner to be sure that it is connected
and set up properly.
9.9.1 Barcode Reader Communication Settings
In order for the barcode scanner to communicate properly with the MCT, it must be set with the proper
communication settings. This includes baud rate, data bits, stop bits, parity and start/end of transmission
characters as follows:
Baud rate = 9600 baud
Data bits = 7
Stop bits = 1
Parity = even
Preamble = STX (0x02)
Postamble = ETX (0x03)
The preamble and postamble are the start of transmission and end of transmission characters that must be
used to frame the barcode transmitted to the MCT so that it recognizes the beginning and end of the
transmission. All other terminator, BCC, ACK and/or handshaking characters must be disabled.
9.9.1.1 Setting up the Unitech MS-120-2 Barcode Scanner
The following instructions are provided for the Future Design Controls recommended Unitech MS-120-2
barcode scanner. These instructions do not apply to other makes or models of scanner. Consult the
manufacturer’s manual for other makes or models for information on how to set the proper communications
settings.
NOTE: The steps below are assuming manufacturer default settings are in place. If the scanner settings are
unknown, restore the scanner to manufacturer defaults by scanning barcode ‘enter group 1’ on page
5 of the MS-
120 Series Programming Manual and then scanning the ‘factory defaults’ barcode at the
bottom of page 5. Scan ‘exit’ to complete the process.
For communication settings see page 11 (RS232 Serial Setting) of the MS-120 Series Programming Manual
Step 1
scan barcode at top of page 11 for ‘enter group 4’
Step 2
scan barcode C2 for parity on page 12 and then scan the barcode for the number 0 on page 11
Step 3
scan barcode C3 for data bit on page 12 and then scan the barcode for number 0 on page 11
Step 4
scan the barcode for ‘exit’ on page 11 to complete RS232 settings
For pre/postamble settings see page 13 (Scanner) of the MS-120 Series Programming Manual
Step 1
scan barcode at top of page 13 for ‘enter group 5’
