When using more than one meter in a multi-drop mode, each meter
must be provided with its own unique address. The meter address
(Slave ID) may be programmed between 1 and 247. The transmit delay
may be set between 0 and 199 ms. The parity can be set to even, odd,
or none with 1 or 2 stop bits.
The PD6000 can also be connected to another PD6000 with a special

ter to another, using the Copy function.
