Configure Modbus Gateway TCP to RTU/ASCII Slave

RTU/ASCII to TCP Slave

CPU : 32-bits ARM7 Winbonds CPU , 80 MHz
RAM : 8 M Bytes SDRAM
ROM : 4 M Bytes Flash ROM
OS : uClinux OS
Ethernet : RJ-45 Connector, 10/100 Mbps (Auto Detect)

Software
TCP to RTU Slave
TCP to ASCII Slave
RTU to TCP Slave
ASCII to TCP Slave

TCP to RTU/ASCII Slave
Operates as a TCP Server
Can be connected by 8 TCP user connection and polling simultaneously
32 simultaneous Request for each TCP Master.

RTU/ASCII to TCP Slave
Operates as a TCP Client
Can connect to 8 TCP servers and polling simultaneously (mapped via user defined Slave ID range)
Can connect up to 256 serial chained RTU/ASCII Slave using 8 units of this Modbus gateway

Note
0 and 245~255 are not recommended to be used as Slave ID if not sure if these numbers are already used or not as ID in the environment. This is because usually 0 is used for broadcast and 245~255 are used for else purpose.
