Modbus RTU Serial
Communications (

serial

)

The meter is equipped with serial communications
capability as a standard feature using Modbus RTU
Serial Communication Protocol.
The meter may be connected to a PC for initial
configuration via the onboard micro USB connection.
For ongoing digital communications with a computer
or other data terminal equipment, an RS-232, or
RS-485 option is required; see

Ordering Information

on page

for details.

•

DO NOT

connect any equipment other than

Precision Digital’s expansion modules, cables, or
meters to the RJ45 M LINK connector. Otherwise
damage will occur to the equipment and the
meter.

Note: More detailed instructions are provided with

each optional serial communications adapter.

Note: Refer to the P

Modbus Register Tables

www.predig.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.

Select Menu (

SElect

)

The

Select

menu is used to select the input signal

conditioner applied to the input (linear), low-value
cutoff, Auto-zero, and analog output programming.
The multi-point linearization is part of the linear
function selection.

Input Signal Conditioning (

Functn

)

The

Function

menu is used to select the input signal

conditioner applied to the input: linear. The multi-point
linearization is part of the linear function selection.
Meters are set up at the factory for linear function with
2-point linearization. The linear function provides a
display that is linear with respect to the input signal.

Multi-Point Linearization (

Linear

)

Meters are set up at the factory for linear function with
2-point linearization. Up to 32 linearization points can
be selected for PV under the linear function. The
multi-point linearization can be used to linearize the
display for non-linear signals.
If the dual-scale Level feature has been selected, the
menus for PV1 & PV2 are enabled. PV2 can be
programmed with up to 8 linearization points.
