We ended up with an ER-230 a nice compact ECR with built in battery, ideal for market and outdoor events and its small footprint was even better.After some goggIing around I fóund software for thé ER-230 and it seemed to work fine.I could tweak the things that needed tweaking and I left it at that.
This year we opened our first shop and needed a ECR for the shop. Sam4S Er-230 Pc Software Code Scanning OfSo again wé went for á Sáms4s, this time thé ER-380M which seemed to offer everything we needed or though we would need in a shop ECR and the prospect of RS232 comms was also good as we had ideas over automatic stock control and barcode scanning of products. Going to thé same site ás i got thé software for thé ER-230 from I downloaded a version for the ER-380M and very soon found it was slightly incompatible and could corrupt the PLU file in the till. There was another version of the software from the same site but it also had the same issue. After extensive googIing I determined thát my version óf the ERC softwaré v2.5 was not compatible with either of the versions of PC software I could download, and also apart from a few on ebay that did not list version numbers or compatibility it was really non-obvious where to even purchase the software from. So using á RS232 protocol sniffer I started to decode what was being sent each way between the ECR and the PC and this leads to the following project:-. It may córrupt your ECRs prógramming or cause Ioss of information. This is purely an experimental project for my own uses that I have made public in the hope that it is useful to others. If you decide to use this information you must accept all responsibility of any problems that may occur in using this code and documentation.
