A customer was interested in using additional features of their industry standard Setra Super count scales. After some struggles they contacted Koehler Scale for assistance. These scales are used for inventory purposes, precisely counting pieces of similar mass. When switching to count a different part, the scale needs to be setup properly for that part. The customer only has a finite amount of parts and the average piece weight of all the parts they are counting are all known. To speed up the process the customer would like to scan a barcode with average piece weight encoded and go straight to counting. This will potentially save several minutes every changeover and prevent setup errors. This setup has a printer and a linear imager sharing 1 bi-directional rs232 port utilizing a cable we custom made to adapt the RJ45 port on the Setra to the common DB9 that most serial devices utilize. After some research we learned this can be accomplished by only using the serial transmit (Tx) from the linear imager and serial receive on printer going to the same port on the Setra. This will prevent serial data from being sent to the scanner and it will prevent the linear imager from sending serial data to the printer and everything will exist harmoniously.
