5. RY CARD PRINT DATA Issue an erase command from the remote capture computer This will set RECORD TXT file size on the card to 0 bytes The flash memory card may also be erased manually on a PC by deleting all files The Model PDXS25 will automatically create a new RECORD TXT with file size 0 bytes PRINTING WHILE MODEL PDXS25 IN PLAY MODE If the users main system issues a print job while the Model PDXS25 is PLAY mode transmitting memory card data to the remote system then the main system will see it as a busy printer and no print data should be lost The busy would be similar to a printer busy state if it was offline or out of paper When the PLAY mode is ended and RECORD is entered then the main system sees a not busy state and Model PDXS25 can resume recording where it left off This busy action is used for any other operating mode of Model PDXS25 to prevent loss of data SETTING BAUD RATE Baud rate is factory fixed to 9600 Baud Model PDXS25 S or 115 2K Baud Model PDXS25 E Approximate thoughput is 960 chars sec for 9600 Baud and 11 500 chars sec for 115K Baud Note The Ethernet connection is currently limited to approximately 11K characters sec SETUP OF REMOTE CAPTURE COMPUTER The user must implement capture software on the capture computer Choose RS232 Serial COM Port or Ethernet connection depending on the model of PDXS25 This may be as simple as Windows Hyperterminal capture software for COM Port connection For Ethern

7. n the flash memory card file size status by issuing a file length query command to Model PDXS25 ASCII String XL see TABLE 1 above STOPPING RECORDING Use mode commands sent by the remote capture PC to control recording Exiting RECORD closes the memory card file RECORD TXT If Model PDXS25 is powered down then the memory card RECORD IXT file will be closed and no data should be lost When RECORD mode is entered again then new print data received will append to RECORD TXT file READING FLASH MEMORY CARD Issue a PLAY command to the Access Control Port The Model PDXS25 will return the contents of the flash Memory Card starting at the beginning The data is streamed out of the Model PDXS25 Access Control Port as if it was going to a printer The PC must capture that data eg Using MS Hyperterminal set to Capture to File Many third party capture software programs are available The user may design the remote site software to control Model PDXS25 and and manage the data The memory card may also be unmounted and read into a PC using a memory card reader The file is named RECORD TXT RECORD TXT FILE This is the file name created on the flash memory card It contains the raw print data received It is 8 bits wide which is then capable of storing images and graphics The data in the file is normally transferred to a remote capture computer using the Model PDXS25 Access Control Module The data can also be transfered to a PC by physicall
8. odel PDXS25 in RECORD mode power up PDXS 25 The distinct alternate blinking of the Green amp Yellow front panel LEDs confirms the unit is in RECORD mode 2 To collect the flash card data without using a capture PC communications link manually carry the flash card to a PC with a card reader or USB card reader Power down before removing the memory card from Model PDXS25 The captured data looks like garbage on a PC an example sP H A lwR RRRACCAAAKe4 R 1 If the users printer cable is not transmitting Generic Text data then the data may contain formating codes escape sequences font loads and even graphics that use byte values ranging from OOHex to FF Hex 256 range Check that a repeat of the print job displays exactly the same garbage character sequences then that indicates it is not random garbage but data that requires conversion using software 2 If the print job is repeated several times and the garbage pattern is not identical then possibly the communication link is not setup correctly eg Baud rate mismatch or Hardware Flow Control missing Cannot obtain any response from Model PDXS25 at remote capture site lf Model PDXS25 was stalled due to some operator event it may be re powered up from the remote site using HARD RESET Command An acknowledge code H string will be returned to the remote site to indicate re established communication At installation no recording can ever be made This may be caused by Model PDX S

11. y moving the card to a PC card reader or USB SD Card reader The card is dedicated to just one file named RECORD TXT and no other file is allowed on the card The maximum file size is approximately 200Megabytes When the card is returned to the ModelPDXS25 any new data recorded will append to the file The RECORD TXT file on the memory card can be erased on a PC or by Model PDXS25 using a Remote Access Module command issued by the remote control PC The RECORD TXT is an exact image of the print stream thus the file data would print to a similar printer for an exact copy of the original printout You may use DOS Prompt command if file is in PC folder eg C gt COPY C RECORD TXT PRN copy file RECORD TXT to printer VIEWING RECORD TXT FILE DATA lf the raw print data is not plain text then a conversion viewing software must be applied to the RECORD TXT file data otherwise the data may appear as garbage in a text viewer eg MS Notepad or Word Many kinds of inexpensive third party software exists to convert for example PCL or Epson emulation raw print data to pdf tiff jog If the raw print data is simple plain text eg Generic Text then the print data is basically readable in simple wordprocessor applications such as MS Notepad or Word or perhaps Excel and other spreadsheets The user may perform formating and parsing of data using a programming language eg Visual Basic to suit an exact application PAGE 2 OF 4 ERASING FLASH MEMO
