Enabling XDriver on the first generation of controllers, 9200, 9400, 9940, 9900 including the enabling of TCP/IP
Older Continuum sites
Connectivity to third Party devices using the old NCI or First Generation Controllers requires an updated file.
For 1st generation controllers, a .upd file is needed to turn on the bit for the Comm port. There is 1 bit per port to enable X Driver then a second bit to enable IP X Driver support required for the Modbus TCP/IP driver. The same principle applies to the generation1, 9200, 9400 controllers.
