Because of the vast differences between various hardware / software manufacturers, we cannot possibly describe how to use our PBCRs for stocktaking. We can however offer this breakdown of the usual stocktake procedure.
Your computer most likely now only has USB ports. We can supply a USB Homebase, but you’ll need to check first that your Z4 DataTraq (or Portable Barcode Reader) will work with it.
You can use ‘Function 00‘ to display the firmware version number – the number in the top right corner has to be at least 407.
If it is, then you can just purchase the USB Homebase, plug it in and you’re set. If it’s a lower number, please contact our service department – your unit may just need a simple firmware upgrade.
To check on the number of scans stored in memory, just press and release the FUNC key, then press and release the 2 key, then press and release the 3 key. This is called ‘Function 23‘.
To check on the amount of free and used memory, just press and release the FUNC key, then press and release the 1 key, then press and release the 0 key. This is called ‘Function 10‘.
The display will show something like this:
This means that 29 characters of memory are currently in use for storing barcodes, and 31,083characters of memory are still available. Each barcode stored takes up the number of characters in the barcode plus one character of overhead to mark the end of each barcode.
The Z4 DataTraq (and earlier models like the Portable Barcode Reader) store every scan into memory, even when the unit is plugged into the PC.
To clear memory, just press and release the FUNC key, then press and release the 1 key, then press and release the 9 key. This is called ‘Function 19‘.
The display will prompt you to confirm that you really do want to clear memory – press the YESkey to clear memory.
