Function Code 16: Write Registers
There are 21 registers in Function Code 16 that can be used to write to the M2. This
manual only describes Register 16 because it can be used to reset an alarm condition. For a
complete description of Function Code 16, request Appendix B from RKI Instruments, Inc.
Register 16
Register 16 performs the same functions as the buttons on the M2. Among other things, it
is useful for remotely silencing alarms. With the M2 in an alarm condition, bit [0] can be
used to silence it.
