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 PD6300 can also be connected to another PD6300 with a special
PDA1200 cable, allowing the user to copy all the settings from one meter
to another, using the Copy function.
