5 Setup and Configuration
5.1 Electrical Configuration Interface
5.1.1 Magnetic Loop
When the CPU detects the presence of a modulated magnetic field, it prepares to receive a setup
message. Immediately after successful programming, the transmitter sends 4 Meter Setup /
Configuration (Type 0) messages in 60 seconds. The message is sent using mode commanded by the
setup command and is then repeated in the mPass mode. The programming tool will wait a specified
amount of time for this message to space programming message attempts. Following this message, a
Meter / Setup Configuration message is transmitted on-air using the configured transmit mode every
60 seconds for 30 minutes.
5.1.2 Optical Direct Serial Connection (optional)
If the programming tool is directly connected to the device via the serial port, feedback to the setup
commands is provided via serial reply messages in addition to the Meter Setup / Configuration (Type
0) messages sent on-air.
5.2 Configurable Parameters
5.2.1 End Point ID
The 28-bit field representing an ID unique to each transmitter (up to 268 million possible ID’s). This
field is set at the factory and is not programmable using the field setup tool.
This connection should only be used by the manufacturing test fixture to prevent electrical
shock.
