Access Levels
Commands can be issued to the relay via the serial port to view metering values, change relay
settings, etc. The available ASCII serial port commands are listed in Figure 8.2 and the
Command Summary at the end of this section. (The Command Summary also can be found in
the Quick Reference section at the end of this instruction manual.) The commands can be
accessed only from the corresponding access level as shown in Figure 8.2 and the Command
Summary. The four access levels are:
