Valid values are in the range 00-7F. b) End String and Define Procedure End String Plus Procedure Read the code to end the string selection and continue defining a new procedure belonging to Method 1. OR End String and Format End String & Format SimijE Read the code to end the string and the format definition. Jj 111 GRYPHON™ D432/D432E 5.3.2 Match Conditions By setting one or more of the following conditions it is possible to select the codes to be formatted. Follow the given steps to define the desired condition: MATCH WITH PREDEFINED SUBSTRING Define Matching Substring Read the above code and: 1. read a number in the range 1-5 corresponding to the desired format number; 2. set the number of characters defining the matching string in the range 00-10; 3. read the corresponding character as Hex value from the Hex/Numeric table identifying the substring character/s. Valid values are in the range 00-7F. (optional) Define Substring Position Read the above code and: 1. read a number in the range 1-5 corresponding to the desired format number; 2. read the number corresponding to the substring position in the range 0-255; AND/OR | MATCH CODE LENGTH Define Code Length Read the above code and: 1. read a number in the range 1-5 corresponding to the desired format number; 2. read the number in the range 0-255; Match Code Length Matching Substring Position Match with Substring 112 CONFIGURATION USING CODE SYMBOLS AND/OR MATCH SYMBOLOGY Define Code Symbology Match Symbology Read the above code and: 1. read a number in the range 1-5 corresponding to the desired format number; 2. set the number of the matching code symbologies in the range 0-4; 3. select the Datalogic Standard Code Identifier from the Code Identifier Table in Appendix C. 113 GRYPHON™ D432/D432E 5.3.3 Format Enable/Disable Format 1 HSHiBjl Sc disabled enabled Format 2 SÊitë = disabled = enabled Format 3 0 = disabled 1 = enabled Format 4 0 = disabled 1 = enabled Format 5 auiSiiE 0 = disabled 1 = enabled Disable All Formats 114 CONFIGURATION USING CODE SYMBOLS 5.3.4 Mismatch Result The result of each format may be set in case the match conditions previously selected are not satisfied. Once the desired formats have been enabled and a code has been read, the results corresponding to each format will be concatenated together and transmitted in the output message. For this reason, it is strongly advised to set the mismatch result for each format. Example Decoded Code: Format definition: Format Enable/Disable Match Condition Function Mismatch Result Format 1 Enabled Code having a length of 16 characters Select field from positionl to position3 No string Format 2 Disabled / / / Format 3 Enabled Code having a length of 25 characters Substitute string "ab" with string "12" Unformatted read code Format 4 Enabled Code having the substring "AT" in position 2 Insert string "789" in position 7 Unformatted read code Format 5 Enabled Code belonging to the PDF417 symbology Delete string "DA" and "pr" Unformatted read code Output message: ^—r-r--. __S'--^ __yV___J ' V V-------Y- Format 1 Format 3 Format 4 Format 5 Define Mismatch Result Read the above code and: 1. read a number in the range 1-5 corresponding to the desired format number; 2. 0 = empty string as output 1 = unformatted read code as output. Mismatch Result 115 GRYPHON™ D432/D432E 6 REFERENCES 6.1 RS232 - USB COM 6.1.1 ACK/NACK Protocol The transmission protocol takes place between reader and Host. Once the reader has read a code, it emits a good read beep and passes its data to the Host. When ACK/NACK is disabled, there is no control from reader to Host transmission. When ACK/NACK is enabled, the Host sends an ACK character (06 HEX) in the case of good reception or the NACK character (15 HEX) requesting re-transmission, in the case of bad reception. If the reader does receive an ACK, no signal will be emitted; whereas, if it does not receive an ACK or NACK, it will emit a wrong reception tone after a few seconds. Gryphon™ D432/D432E reader cannot read barcodes while waiting for the Host response. NOTE 6.1.2 RX Timeout This parameter can be used to automatically end data reception from the Host after the specific period of time. If no character is received from Host, after the timeout expires, any incomplete string (any string not terminated by ) is flushed from the device buffer. 116 REFERENCES 6.2 USB KEYBOARD 6.2.1 Keyboard Speed This parameter manages the transmission speed of characters to the Host. A fast Keyboard Speed allows rapid transmission of a great amount of characters (for example 2D codes), but it might not be compatible with slower systems. 6.3 CODE SELECTION 6.3.1 Issue Identical Codes This parameter manages the code transmission when more than one code containing the same information is detected in...
