Each communications port can individually select an Edit Setpoint Group of interest by
writing address 1342h. This way the front port, rear port and auxiliary port can read and
alter different setpoints simultaneously.
Each communications port can individually set the Passcode Access by writing address
88h with the correct Passcode. This way the front port, rear port and auxiliary port have
individual access to the setpoints. Reading address 0203h,
register, provides the user with the current state of access for the given port. A
ACCESS
value of 1 read from this register indicates that the user has full access rights to changing
setpoints from the given port.
