About the Gallagher TW & TWR series
The TWR series
All Gallagher TWR devices are a weigh scale and reader, meaning it has an EID reader built into the unit.
The Gallagher TWR series is a data logger. A datalogger brings in multiple strings of data e.g. EID, weights, traits etc.....
A Gallagher TWR series has the option to be set as a weigh scale only OR a weigh scale and reader combined.
The TW series
All Gallager TW devices are a weigh scale only and therefore only bring in the weight.
All Gallagher TW devices are connected as Gallagher/Ruddweigh KM3/300..800 in SB
Note, a Gallagher TW series can be set as a datalogger - i.e. when paired to another device such as a reader and then connected to SB - not recommended
It is important to identify which series and model you are connecting.
The Model can be found on front of the device below the screen.
The TWR-5

The TWR-5 can be connected as a Datalogger (scale and reader combined) or as a Ruddweigh (scale only).
