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 questions 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 second PDW30 unit. The secondary unit then recreates that signal at its location. The secondary
unit may also transmit its 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 repeaters, are available. The antenna may be directly attached or remotely located. High gain directional antennas are also offered.

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 diagram at right.
The analog input will not interfere with any existing HART signal on a 4-20 mA current loop. However, the HART 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 always 4-20 mA, regardless of the input type on the other wireless 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
output 12 mA.
Connect the mA OUT terminals to a device scaled to read a
4-20 mA signal.
The analog output is internally powered; no external power
supply is required.

Figure 6. Digital I/O Connections
Digital I/O Connector
All digital connections are referenced to ground. The primary
unit digital I/O settings determine the settings of the secondary unit (e.g. if D1 of the primary unit is an input then D1 of
the secondary unit in an output).
Note: Each connection may be set independently in the de-
vice settings as either an input or an output. In the diagram 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 enabled devices may be transmitted wirelessly using the PDW30 Wireless Bridge.
Note: Modbus Master must be connected to Primary Wireless Unit.
Notes:
1. Termination resistors are optional and values depend on the cable length and characteristic impedance. Consult the cable manufacturer for recommendations.
2. Use shielded cable, twisted-pairs plus ground. Connect ground shield only at one location.

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, simplifying 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.

Analog Input Setup
Enter the Analog Input menu to set up the wireless unit to accept either a current or a voltage input.
The current input is capable of accepting a signal from 4 to 20 mA. The voltage input is capable of accepting a 0 to 10 VDC signal, 0 to 5 VDC signal, or 1-5 VDC signal.
Digital I/O Setup
All four digital connections may be set as either inputs or outputs. The setting on the primary unit determines the corresponding digital connection on the secondary unit. For instance, if digital connection number 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.

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 parity, 1 stop bit), 8O1 (8-bit, odd parity, 1 stop bit), or
8N2 (8-bit, no parity, 2 stop bits).

Programming with PDW Manager
PDW Manager allows you to program the PDW30 wireless units from a PC with a USB connection. Units
connect to a PC via the micro USB connection on their face, underneath the enclosure cover. Use of
PDW Manager is required for programming advanced settings such as wireless encryption and analog
signal calibration.
.
Once the software is running, power the unit using a 12-28 VDC power supply and connect the device to
the PC using the provided USB cable.
The PC will automatically install the appropriate device drivers. Once this has completed, the device will
appear in the Device list at the top of the PDW Manager window. Click Connect.
The menu options displayed will vary depending on what type of unit is connected. The PDW30 primary
unit will have more options than the secondary unit. The image below shows the available options on the
configuration tab while the primary unit is connected.

they are connected. If devices connect, consider placing closer together permanently, removing any obstacles, or mounting higher.
• Ensure antennas are on parallel plane. Devices that are vertically separated will not
have as strong of a connection.
• If communicating over distance of miles, consider installing PDW30-RNA repeaters or a
high gain directional antenna.
Multiple wireless
devices in the
area with the
same ID.
• If there are multiple PDW30 wireless bridges,
verify that each pair has its own unique network ID.
Encryption keys
do not match
• If using encryption, ensure that the encryption keys on both devices match exactly.
Intermittent signal issues.
Signal is too poor.
• Check RSSI. If signal is too low, consider
moving devices closer together, clearing obstacles in wireless path, or mounting devices
higher.
• Ensure devices are on parallel plane.
• If communicating over distance of miles, consider installing high gain directional antenna.
Temporary obstacles are blocking
the wireless path.
• Temporary obstacles, such as large trucks or
heavy equipment, can interfere with wireless
path. Consider moving wireless units higher
or to an area with less traffic.
