RS485 Communications
devices on a single pair of wires, distances up to 4,000 ft. and data rates as high
as 10M baud (the LD is limited to 38.4k baud). The same pair of wires is used
to both transmit and receive data. RS485 is therefore always half-duplex, that is,
data cannot be received and transmitted simultaneously.
3.4 INPUT WIRING
inputs are wired using the six position terminal block (TBB) located inside the
unit on the right side.
3.5 SERIAL WIRING
unit on the left side for the LD2 and on the right side for the LD4.

RS232 Communications
50 feet. Data Terminal Equipment (DTE) transmits data on the Transmitted Data
(TXD) line and receives data on the Received Data (RXD) line. Data Computer
Equipment (DCE) receives data on the TXD line and transmits data on the RXD
line. The LD emulates a DTE. If the other device connected to the meter also
emulates a DTE, the TXD and RXD lines must be interchanged for
communications to take place. This is known as a null modem connection. Most
printers emulate a DCE device while most computers emulate a DTE device.
without a pause in between. In these cases, the meter employs a busy function.
determine if the receiving device is “busy”. The receiving device asserts that it
is busy by setting the RXD line to a space condition (logic 0). The meter then
suspends transmission until the RXD line is released by the receiving device.
