Hello everyone,
I am after some advice. I want to directly connect my Geller register to my PC database management system, I don't want to use the Geller David software. I have contacted Geller but they will not give me any information on the data protocol that is used. Does anyone know whether this is even possible? As far as I can gather, the register does not push the data to the port, instead you have to pull it, so either the computer or a device will need to query the register. However might the data locked, or encrypted or not accessible in some other way. I read somewhere that it might be in standard ASCII format, but that sounds too simple. In fact does anyone know about data protocols for other makes of registers.

All advice/opinions would be much appreciated.

Thanks

The geller range of tills use batch processing. That means you have to request the data to be sent with some very easy protocols.

I have most of the protocols if you want them.

Let me know.

could you please send me some protocol infomation for geller registers to superstock

me too, could you send me protocols please.
