GBS Elektronik MCA-527 Firmware Commands - Manual (Page 4)

MCA527
The Ethernet communication uses the UDP protocol with the destination port 50000. The preamble is
prefixed 2 bytes (0xA5, 0x5A) for intern byte alignment within the MCA527.
The MCA527 can be configured to use a fixed customized IP address or to obtain the IP address
automatically from a DHCP server or if not available, to use Zero Configuration Networking (also named
Automatic Private IP Addressing).
While the MCA527 is writing a file, only the query commands and CMD_STOP command are executable. All
other commands are ignored and response with an error value. The file writing state is returned by
CMD_QUERY_STATE527_EX.
