Dear all,


does anyone has the experience on assigning Modbus address into a chip ? i been trying to send out the Modbus ASCII frame for MOXA gateway to recognize it from my chip. Unfortunately, moxa gatway unable to recognize it. 



i did send out the frame ":F7031389000A60<CR><LF>" , in order to communicate between my chip and the gateway. but, it shows illegal packet.



Anyone has any experience or some sharing on this ? i do need your help.
