Introduction
The Precision Digital PDW30 gives you a simple, straightforward way to get an analog, discrete,
or Modbus®signal from where you have it to where you need it. It’s a point-to-point wireless
bridge packaged in a rugged, weather tight housing designed to meet the demands of industrial
installations.
The PDW30 is simple to order, simple to configure, and easy to trust with your application.
Guaranteed ranges assure it will work with your application, or you can send it back - no ques-
tions asked. A wireless survey tool is available for those who may require a site survey for
longer distances, making it easy to verify the installation will work the first time.
The PDW30 takes an analog, discrete, or Modbus®input and wirelessly broadcasts it to a sec-
ond PDW30 unit. The secondary unit then recreates that signal at its location. The secondary
unit may also transmit it’s own analog, discrete, or Modbus signals back to the primary unit. Just
put the units in the field anywhere you have a signal and power.
A wide range of accessories, including mounting kits, antenna-related accessories, and repeat-
ers, are available. The antenna may be directly attached or remotely located. High gain direc-
tional antennae are also offered.

Pre-Installed Conduit Plug
The PDW30 is supplied with one pre-installed optional conduit plug for installations that do not require the
use of both conduit entries. The conduit plug includes an internal hexagonal socket recess for removal.
Mounting Instructions
The PDW30 has two mounting holes that may be used for a 1.5” pipe mounting or wall mounting. Alterna-
tively, the unit may be supported by the conduit using the conduit holes provided. The antenna is
threaded into one of the three conduit holes and may be moved as appropriate for the installation.
It can also be mounted by using the PDA6963 mounting bracket in order to orient the device antenna
away from the pipe. Refer to Mounting Dimensions on page 28 for details on wall or panel space require-
ments.
Cover Jam Screw
The cover jam screw should be properly installed once the meter has been wired and tested in a safe en-
vironment. The cover jam screw is intended to prevent the removal of the meter cover in a flameproof en-
vironment without the use of tools. Using a M2 hex wrench, turn the screw clockwise until the screw con-
tacts the meter. Turn the screw an additional 1/4 to 1/2 turn to secure the cover.
Caution: Excess torque may damage the threads and/or wrench.

Connections
To access the connectors, remove the enclosure cover and unscrew the two captive stainless steel
screws. Remove the electronics assembly from the enclosure. Signal connections are made to removable
terminal blocks on the back of the electronics assembly. Grounding connections are made to the two
ground screws provided on the base –one internal and one external.
Static electricity can damage sensitive components.
Observe safe handling precautions for static-sensitive com-
ponents.
Use proper grounding procedures/codes.
Warning!
Observe all safety regulations. Electrical wiring should be per-
formed in accordance with all agency requirements and appli-
cable national, state, and local codes to prevent damage to
the meter and ensure personnel safety.

Power Connector
Power connections are made to a two-terminal connector
labeled POWER in Figure 1. The meter will operate re-
gardless of DC polarity connection. The + and - symbols
are only a suggested wiring convention.
Make sure that the power supply can provide between 12
and 28 VDC to the wireless device.
Signal Connector
The analog input may be either 4-20 mA, 0-10 V, 0-5 V, or 1-5
V. The appropriate input type must be programmed for each
unit.
Once the appropriate input type has been programmed, wire
the analog signal source to the device as shown in the dia-
gram at right.
The analog input will not interfere with any existing HART sig-
nal on a 4-20 mA current loop. However, this signal will not be
transmitted wirelessly.
4-20 mA Output Connector
The 4-20 mA output corresponds with the analog input signal
on the paired wireless device. The analog output signal is al-
ways 4-20 mA, regardless of the input type on the other wire-
less module.
For instance, if the analog input type on the first device was 0-
10 V and the input value was 5 V, the second device would out-
put 12 mA.
Connect the mA OUT terminals to a device scaled to read a 4-
20 mA signal.

Digital I/O Connector
All digital connections are wired to ground. The primary unit
digital I/O settings determine whether a digital connection re-
ceives power constantly or intermittently, thereby determining
whether it is an input or an output, respectively.
Note: Each connection may be set independently in the de-
vice settings as either an input or an output. In the dia-
gram to the right, D4 & D3 are digital inputs and D2 is a
digital output.
Modbus RTU Serial Communications
The PDW30 acts as a simple pass-through for Modbus communications. As such, multiple Modbus ena-
bled devices may transmit wirelessly using the PDW30 Wireless Bridge.

Setup Menu
The setup menu consists of analog, digital (discrete), and Modbus®input/output settings, network ID,
password, and factory defaults restoration.
The primary wireless unit determines network protocol and digital I/O settings for the secondary unit, sim-
plifying the setup process. For instance, if a digital connection is programmed to be an input on the pri-
mary unit, that same connection will be an output on the secondary unit. Because of this, the secondary
wireless unit has fewer menu options than the primary unit.

ber one is set as an input on the primary unit, it will be an output on the secondary unit.
Each digital connection may be set independently as either an input or output.

Network and Modbus Setup
The Network and Modbus Setup menu is where the wireless device’s Network ID is set and Modbus®se-
rial communications settings are programmed.
Network ID
The network ID determines primary and secondary wireless pairs. The primary and secondary
units must share the same unique network ID in order to communicate.
Modbus Timeout
The Modbus timeout sets the length of time the wireless devices will wait for a reply from the
other Modbus device before returning an error. This should be 1 to 2 seconds at 9600 bps on the
primary device.
Modbus Baud Rate
The baud rate of the wireless devices must match the baud rate of the Modbus network in order
to prevent collisions on the bus. The baud rate may be set between 1,200 and 57,600 bps.
Data Format
The data format of the wireless devices must match the data format of the Modbus network. Set
the data format to either 8E1 (8-bit, even parody, 1 stop bit), 8O1 (8-bit, odd parody, 1 stop bit), or
8N2 (8-bit, no parody, 2 stop bits).

Password Setup
Both the primary and secondary wireless units may be protected with a four digit numeric password in or-
der to prevent unauthorized tampering. When a password has been set, you will be prompted to enter
that password in order to access the device menu.
To disable password protection, simply enter 0000 as the password.
Note: See Entering Numeric Values on page 16 for instructions on how to enter numbers
Making Changes to a Password Protected Meter
Once a password has been set on the device, you will be required to enter that password before being
allowed to access the device menu.
Note: Setting a password will require you to enter the password to access the device settings via the PC
software as well.
Did you forget the password?
Connect the device into a PC running PDW Manager and
select reset all device parameters to factory defaults.
Restore Defaults
If a mistake has been made while programming the primary or secondary device, and it is unclear where
the error occurred, the best option may be to perform a factory reset of the device and begin again.
