)
The meter is equipped with serial communications capability as a
standard feature using Modbus RTU Serial Communication Protocol.
To communicate with a computer or other data terminal equipment, an
RS-232, RS-485, or USB adapter (DPA8008) option is required; see
Ordering Information
on page 9 for details.

communications adapter.

Register Tables located at www.omega.com
for details.
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 DP6000 can also be connected to another DP6000 with a special
DPA1200 cable, allowing the user to copy all the settings from one
meter to another, using the
Copy
function.
Warning!
Do not connect any equipment other than OMEGA’s
expansion modules, cables, or meters to the RJ45
M-LINK connector. Otherwise damage will occur to
the equipment and the meter.
