transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending
another command. This allows enough time for the meter to process the
command and prepare for the next command.

Auto/Manual Mode Register (MMR) ID: U
meter controls the setpoint output. In Manual Mode (1) the outputs are defined
by the registers SOR. When transferring from auto mode to manual mode, the
meter holds the last output value (until the register is changed by a write). Each
output may be independently changed to auto or manual. In a write command
string (VU), any character besides 0 or 1 in a field will not change the
corresponding output mode.
Setpoint Output Register (SOR) ID: X
Reading from this register (TX) will show the present state of all the setpoint
outputs. A “0” in the setpoint location means the output is inactive and a “1”
means the output is active. The output logic parameter in Module 6 will affect
the active logic state.
Mode, writing to this register (VX) will change the output state. Sending any
character besides 0 or 1 in a field or if the corresponding output was not first in
manual mode, the corresponding output value will not change.
SERIAL TIMING
This register sets the controlling mode for the outputs. In Auto Mode (0) the
U abcd
This register is used to view or change the states of the setpoint outputs.
X abcd
In Automatic Mode, the meter controls the setpoint output state. In Manual
Example: VX10* will result in output 1 active and output 2 inactive.
Example: VU0011 places SP3 and SP4 in manual.
