Network commands
The following commands are network commands.
DT (Destination Address)
Sets or displays the networking address of a device. The devices use three filtration layers:
n Vendor ID Number (ID)
n Channel (HP)
n Destination Address (DT)
The DT command assigns an address to a device that enables it to communicate with only devices
that have the same address. All devices that share the same Destination Address can communicate
freely with each other. Devices in the same network with a different Destination Address than the
transmitter listen to all transmissions to stay synchronized, but will not send any of the data out their
serial ports.

HP (Preamble ID)
Set or read the device's hopping channel number. A channel is one of three layers of filtration available
to the device.
In order for devices to communicate with each other, the devices must have the same channel
number since each channel uses a different hopping sequence. Devices can use different channels to
prevent devices in one network from listening to transmissions of another.
When a device receives a packet it checks HP before the network ID, as it is encoded in the preamble
and the network ID is encoded in the MAC header.
