TCP Master to RTU/ASCII Slave
8 simultaneous TCP user connection and polling, 244 serial chained RTU/ASCII Slave.
32 simultaneous Request for each TCP Master.

RTU/ASCII Master to TCP Slave
8 simultaneous TCP user connection and polling (mapped via user defined Slave ID range)

Note
Slave ID is not recommended to use 0 and 245~255 if you are not sure if these numbers are already used or not as ID in your environment. Because usually 0 is used for broadcast and 245~255 are used for else purpose.
