Command Summary
The serial port commands at the different access levels offer varying levels of
control:
➤ The Access Level 1 commands allow you to look at
information only (settings, metering, etc.), but not to change it.
➤ The Access Level E commands allow you to reset meter
registers, including peak demand.
➤ The Access Level 2 commands allow you to change meter
settings.
The meter responds with
Invalid Access Level if a command is entered
from an access level lower than the specified access level for the command.
The following example shows how the meter responds to commands not listed
above or entered incorrectly.
Invalid Command
Many of the command responses display the following header:
FEEDER 1 Date: 01/01/02 Time: 00:01:07.175
STATION A Time Source: int
➤ FEEDER 1: This is the MID setting (the meter is shipped with
the default setting MID = FEEDER 1; see Identifier Labels on
page 9.11).
➤ STATION A: This is the TID setting (the meter is shipped with
the default setting TID = STATION A; see Identifier Labels on
page 9.11).
➤ Date: This is the date the command response was given (except
for meter response to the EVE [Event] command, where it is
the date the event occurred). You can modify the date display
format by changing the DATE_F meter global setting.
➤ Time: This is the time the command response was given
(except for meter response to the EVE command, where it is
the time the event occurred).
➤ Time Source: This is the time source status at the time of the
