Chksum: ‘000’ to ‘999’ this is a simple additive chksum of the decimal values of the Status page.

NOTE: Since the MX address is an alpha character, it’s checksum needs to be calculated

differently then the FX’s numerical address. Addresses reported for the MX/FM will be ‘A” (ASCII 66)
through ‘K” (ASCII 75) corresponding to ports 1-10. The value to use for Chksum calculations should
be the received ASCII value – 48 (For the received character ‘A” the chksum value to be used would be
65-48, or 17.

Example:
A,00,08,06,034,031,00,05,000,02,262,000,000,059
17+0+0+0+8+0+6+0+3+4+0+3+1+0+0+0+5+0+0+0+0+2+2+6+2+0+0+0+0+0+0=059

D,00,07,05,034,031,04,05,000,02,262,000,000,064
20+0+0+0+7+0+5+0+3+4+0+3+1+0+4+0+5+0+0+0+0+2+2+6+2+0+0+0+0+0+0=064
