7.1.2.3.4. COMLI
COMLI is a serial polling-type communication protocol used by Master-Slave application. When M!DGE3
radio network in Router mode is used, more COMLI Masters can be employed within one Radio network
and one Slave can be polled by more Masters. Broadcast packets are not used.
The frame of COMLI protocol is sent transparently, but without STX, ETX and BCC. STX (start of data),
ETX (end of data) and BCC (8-bit XOR) are added on the receiving participant. While transfer, data
integrity is properly secured by individual protocol checksums.
Note
The COMLI protocol in the M!DGE3 is not fully compatible on COM port with M!DGE3 and MR
modems. M!DGE3 implementation is not supporting “Intercharacter tx delay”.
