1 Overview
This document describes how to set up and use WITS communication with EDR version
3.12.0 or later.
The Wellsite Information Transfer Specification (WITS) is a communication protocol
used to transfer wellsite data between computer systems. The WITS specification is an
industry-wide standard used by companies involved in petroleum exploration and
production.
The Pason Electronic Drilling Recorder (EDR) can use WITS to communicate with
another service company’s equipment. Service companies, referred to as a third parties
in this document, may only need to receive specific data, or send specific data to the
EDR, but in most cases, they want to both send and receive data. Using WITS is a
proven and reliable way to accomplish these goals.

2 Understanding Pason WITS
2.1 Setting Up
Setting up and using WITS with a Pason EDR involves these general steps:
1. Physically connecting third-party hardware to the Pason system
2. Establishing WITS communication between the third-party device and the EDR,
often called handshaking
3. Setting up the EDR for WITS communication
4. Setting up the third-party device for WITS communication
The second step, establishing WITS communication, is typically where most problems
occur. To avoid WITS-related problems, consider the information below about WITS in a
Pason system.
2.2 Duplex Communication
Pason recommends full duplex communication when using WITS. With full duplex
communication, data can travel in two directions simultaneously. This is different than
half duplex communication, which allows data to travel in one direction at a time, like
voices on walkie-talkie radios.
2.3 Handshaking
Establishing and maintaining WITS communication between connected WITS devices
and the EDR requires a handshaking procedure. For details about how to complete the
handshaking process, see About Handshaking on page 14.
2.4 About WITS Levels and Packets
The Pason system uses WITS Level 0 for serial communications. In Send and Receive
mode, the EDR transmits a number of WITS Level 0 packets (1 packet in Half WITS
mode, approximately 8 packets in Full WITS mode) each time it receives a valid WITS
Level 0 packet.
2.5 What is the 1984PASON/EDR Header
Every WITS record the Pason EDR sends includes a 1984PASON/EDR header. This
does not exactly meet the WITS specification, which specifies that items from different
Revised May 1, 2019
Revision 25 of DOCU225, © Copyright
Page 8 of 44
records should be in different packets. However, this item is required due to the half
duplex nature of our communication cables. The EDR uses this header to distinguish
between sent data and received data.
If a WITS device requires the removal of the 1984PASON/EDR header, ensure that the
device is connected to the EDR via a COMM022, and that its EDR comm port is set to
Send Only. Refer to Setting the Send/Receive Mode on page 17 for step-by-step
instructions.

3 Connecting Hardware for WITS Communication
WITS communication requires a physical connection between Pason and third-party
systems. This section includes information about how to complete the required hardware
connections.
3.1 Connection Instructions for Third-Party Users
Third parties can connect their systems to Pason’s using one of these three methods:
• Connect to a Pason Workstation computer (TPC and VSP systems).
• Connect to the toolpush connection box (TPC systems) or network panel
(VSP systems).
• Connect to a Pason Doghouse Computer (DHC), SideKick, or Universal
Junction Box (UJB) (TPC and VSP systems).
Important:
Pason only supports the three above methods to connect WITS devices to our system.
Specifically, note that the RS-232 ports on trailer access points (TAPs) do not support WITS
connections. WITS connections to TAPs haven’t been fully tested and their reliability is unknown.
Connecting a WITS device to a DHC or SideKick can in some cases adversely affect wireless
communications between the DHC and the network.
All of the parts and cables described in the following connection procedures are
available for purchase from your Pason representative.
Once third parties connect their hardware, Pason recommends that a Pason field
technician inspect the connections and complete the initial WITS set up in the EDR.
Connecting a WITS Device via a Pason Workstation
Connecting a WITS device via a Pason Workstation is the most common connection
method. Follow these steps to connect a WITS device to the EDR via a Pason
Workstation:
1. Ensure that the Pason Workstation is powered on.
2. Use a Pason Send to Hub cable (CBLASS155), or a generic DB9 9-pin serial null
modem cable, to connect the WITS device to comm port 1 on the Pason
Workstation as shown in Figure 1.

Figure 1: Connecting a WITS device to a Pason Workstation
Connecting a WITS Device via the Toolpush Connection Box or Network Panel using a COMM022
This method involves using an RS-232 to RS-422 communication box (COMM022) to
connect the WITS device. Toolpush connection boxes and network panels are typically
located on an outside wall of the rig manager’s trailer. Look over the illustrations below
to see the connections to the different types of panels. Figure 4 on page 11 shows a
COMM022 in more detail.
Note:
Pason COMM022 communication (comm) boxes ship with full duplex communication enabled.
COMM022 comm boxes have a jumper that enables you to choose half or full duplex, but Pason
recommends using the default full duplex setting.

WITS Device port
When connecting a WITS device in potentially hazardous areas, use the Hazardous
Area WITS Interface Assembly (COMM087) instead of COMM022. COMM087 is
certified for Class 1 Division 2 areas. Follow these steps to connect COMM087 to the
EDR via a Pason DHC, SideKick, or UJB:
1. Ensure that the DHC, SideKick, or UJB is powered on.
2. Secure the WITS to RS232, 6 ft. cable (CBLASS390) to the WITS Device port on
the Hazardous Area WITS Interface Assembly (COMM087). Secure the female
DB-9 end to the WITS device.

3. Connect a RigComm RS-422 cable to the RigComm port on COMM087. Connect
the other end to any available powered RS-422 port on the DHC, SideKick, or
UJB, as shown in Figure 6. If connecting to a SideKick, use the 2.5ft Power
Rignet Y-Adapter cable (CBLASS360) to create the powered port.

Important:
If connecting to a SideKick, ensure that the port you’re using is set to Auto (Port Info >
Port Setup from the SideKick’s main screen). If connecting to a UJB, ensure the port is
set to WITS (Setup Ports > Change to WITS from the UJB local interface). This requires
UJB firware version 11 or higher.

3.2 Testing WITS Connections
If you are having problems with WITS communication, a Pason field technician can test
WITS connections using the proprietary Pason WITS RSVP application. For help testing
your WITS connections, contact Pason Technical Support at 1-877-255-3158.

4 Setting Up WITS in the EDR
After connecting the hardware, you need to use the EDR to set up WITS communication.
Set up procedures vary depending on whether you connected the WITS device to the
EDR via a comm box or via a Workstation, DHC, or SideKick. The following sections
describe the required procedures.
4.1 Set up on UJB
If connecting to a UJB, ensure the port is set to WITS. This requires UJB firmware
version 11 or higher. Select Setup Ports > Change to WITS from the UJB local
interface. Then select either WITS 9600 or WITS 19200.
4.2 About Handshaking
Setting up and maintaining WITS communication between a WITS device and the EDR
requires the use of a handshake. The handshake is important because it prompts the
EDR to recognize that a WITS device has been connected to the system, and is
necessary for the EDR to keep WITS communication active. If you connected the WITS
device via a toolpush connection box or a network panel, handshaking also prompts the
EDR to display a WITS protocol in the Comm Port Setup screen, so handshaking is
useful for determining which ports are connected to WITS devices.
Important:
Failure to continuously send at least one packet to the EDR every 30 seconds causes the EDR’s
communication engine to time out, stopping WITS communication. This is a major cause of WITS
communication problems.
Establishing and Maintaining WITS Communication
To establish and maintain WITS communication with the EDR, the third-party WITS
device must send at least one WITS packet to the EDR continuously every 30 seconds,
even if the third-party has no other need to send WITS packets. The only exception to
this requirement is when the WITS device is connected via a toolpush connection box or
a network panel, and the EDR comm port is set to Send Only. This requirement can be
met in one of the following two ways:
• The third-party WITS device continuously sends at least one WITS packet to the
EDR every 30 seconds as part of the desired operation, or
Revised May 1, 2019
Revision 25 of DOCU225, © Copyright
Page 15 of 44
• The third-party WITS device is set up to continuously send a handshaking packet
to the EDR every 30 seconds. Pason recommends continuously sending a TVD
WITS packet configured as shown in Figure 7. The EDR is coded to recognize
and use this specific packet for maintaining WITS communication, but can also
receive TVD WITS packets with actual values from other WITS devices at the
same time. The EDR is capable of receiving this handshaking packet from
multiple WITS devices simultaneously.
Be sure to include all of the carriage return and line feed characters shown
below.

4.3 Setting up the EDR Comm Port
Setting up an EDR Comm Port for WITS Connections via a DHC, Workstation, SideKick, or UJB
If you connected the WITS device to the EDR via a DHC, Workstation, SideKick, or UJB,
the device doesn’t appear in the EDR Comm Port list. In these cases, you do not need to
set up a comm port. To determine if WITS is working in these setups, check the WITS
monitor, check the EDR for WITS traces sent by the third-party device, or check the
third-party device for WITS values sent by the EDR.
Important:
As a best practice, Pason recommends connecting WITS devices before setting up comm ports
and configuring WITS in the EDR.
Setting up the EDR Comm Port for WITS Connections via Toolpush Connection Box or Network Panel
If you connected the WITS device to one of these panels with a COMM022, the EDR
assigns the device a comm port. The EDR also enables you to select a transmission
speed (in bits per second) for connected comm ports, but Pason strongly recommends
using the default Auto setting.
To set up the EDR comm port, you need to determine the assigned comm port and then
configure it.
Revised May 1, 2019
Revision 25 of DOCU225, © Copyright
Page 16 of 44
Determining the Assigned Comm Port for WITS Connections via Toolpush Connection Box or Network Panel
The EDR uses several comm ports for communicating, so you need to determine which
port the EDR uses for WITS.
Follow the steps below to find the assigned port if you connected the WITS device to the
TPC via a COMM022:
1. Connect the WITS device and have it send any WITS value to the EDR.
2. From the EDR main screen click Menu > Setup > Comm Ports. The Comm Port
Setup screen opens.
3. Use the navigation buttons to scroll through the comm ports list until you see a
comm port showing one of the following under New Protocol: WITS 9600 (8,N,1),
WITS 115200 (8,N,1), WITS 230400 (8,N,1), WITS 460800 (8,N,1), or WITS
921600 (8,N,1). Comm ports connected to WITS devices display one of these
WITS protocols.
Setting the Assigned Comm Port’s Transmission Speed for WITS Connections via Toolpush Connection Box or Network Panel
Every EDR comm port has a protocol that defines transmission speed (in bits per
second) and serial port parameters. All EDR WITS protocols use serial port parameters
of 8,N,1, but each protocol includes a unique transmission speed. For example, the
protocol labelled “WITS 9600 (8,N,1),” uses a transmission speed of 9600 bits per
Figure 8: Comm port with a WITS connection
Revised May 1, 2019
Revision 25 of DOCU225, © Copyright
Page 17 of 44
second. To change the transmission speed, select a protocol that uses the desired
speed.
Important:
High speed settings are a major cause of WITS transmission errors. For WITS, Pason
recommends using a speed of 9600 bits per second. If you experience errors when using WITS,
try decreasing the transmission speed.
Follow the steps below to configure the assigned WITS comm port protocol if you
connected the WITS device to the TPC via a COMM022:
1. From the EDR main screen click Menu > Setup > Comm Ports. The Comm Port
Setup screen opens.
2. Select the assigned comm port and use the Toggle Next button to scroll through
the list of available protocols until the desired protocol is listed under Configured
Protocol.
3. Click Exit to save the settings.
4.4 Setting the Send/Receive Mode
How you connect the WITS device to the Pason system determines which Send/Receive
options are available.
Send/Receive Options for WITS Connections to a DHC, Workstation, SideKick, or UJB
DHC, Workstation, SideKick, and UJB hardware is hard-coded to send and receive, so
you cannot use send only mode or receive only mode when you connect to a WITS
device via these devices. With these setups, the handshaking procedure on page 14
instructs the EDR how to communicate with the WITS device.
Send/Receive Options for WITS Connections via Toolpush Connection Box or Network Panel
If you connected the WITS device to one of these panels with a COMM022, you can set
the EDR to send WITS data, to receive WITS data, or to send and receive WITS data.
Once you have connected to the TPC via a comm box and have established a
handshake as described in Establishing and Maintaining WITS Communication on page
14, follow the procedure below to set up whether the EDR sends, receives, or sends and
receives WITS data through the assigned comm port:
1. From the EDR main screen on the RMPC, click Menu > Setup > Comm Ports.

2. Select the assigned WITS comm port as described in Determining the Assigned
Comm Port on page 16.
3. Click either Toggle Next or Toggle Prev to turn off the Auto setting and toggle
through the additional protocols.

to use (Send and Receive, Send Only, or Receive Only). If you select Send Only
mode, the EDR displays a Use 1984 Header box that enables you to add or
remove Pason’s 1984PASON/EDR header (refer to What is the
1984PASON/EDR Header on page 7)
Figure 10: WITS Comm Options screen
6. When you are finished, click OK. The EDR returns to the Comm Port Setup
screen.
7. Click Exit to return to the EDR main screen.
4.5 Selecting WITS Codes
There are several ways to specify which WITS codes the EDR sends, as described
below, but the EDR is hard-coded to receive specific codes. The EDR can receive WITS
record 01, 02, 07, 08, 09, 11, 12, 17, 18, and 63 packets, plus custom WITS codes (see
the full table of valid WITS codes in Default Pason WITS Codes on page 32). If you need
the EDR to receive a code not listed in the table, you need to set up a custom WITS
code as described in Configuring Custom WITS in the EDR on page 24.
Depending on the type of workstation you are logged on to, the WITS setup screen in
Figure 11 on page 23 includes the elements in the table below.

7. For each of your selections, enter the following information:
• Code: Enter a WITS code for the trace by clicking under Code in the trace's
row. If the code you enter conflicts with a code already in use, the EDR
displays an error message in the Status Message box and doesn't allow you
to save the changes.
• Units: Click under Unit in the trace's row and choose the units from the drop-
down list. Note that these are display units only—the EDR doesn't perform
conversions based on the units you select.
• Data Summary: If you've chosen a depth or time-based transmission type,
use the Data Summary drop-down list to select how the EDR calculates the
WITS value.
8. When you are finished configuring, click Save > Exit to return to the Setup Menu.
4.6 Configuring Custom WITS in the EDR
If you need to send or receive data not listed in the table of Default Pason WITS Codes
on page 32, you must set up a custom WITS code. Once a custom WITS code is set up,
the EDR can receive it from any connected WITS device, but you need to follow the
steps in Selecting Custom WITS Codes to Send on page 27 to instruct a Pason
computer to send custom WITS codes.
Setting up Custom WITS Codes
To set up a custom WITS code, use the following procedure:
1. From the EDR main screen on the RMPC, click Menu > Setup > WITS. The
WITS setup screen opens.
2. On the WITS In All tab, click the Custom button. The Custom WITS setup screen
opens. This screen displays 50 editable custom WITS codes, names, units,
adjustable decimal spaces, and shelf lives.

and units by
clicking in any
Figure 12: Highlighted custom WITS row
3. Click in a code’s row. The EDR highlights the row.
4. Within the highlighted row, enter the following custom code information:
• Code
Enter a WITS code for the trace by clicking under Code in the highlighted
row, and entering a four digit WITS code. Ensure that this code is different
from the existing WITS codes. If the code you enter conflicts with a current
EDR WITS code, the EDR highlights your entry in red and does not allow you
to save your settings.
• Name
To enter a name for the custom WITS code, click under Name in the
highlighted row and enter a name.
• Unit
To select the display units, click under Unit in the highlighted row and enter
the name of the display units. Note that these are display units only—the
EDR does not perform conversions based on the units you enter.
• Decimals
To select the number of decimal places the EDR uses for the WITS value,
Revised May 1, 2019
Revision 25 of DOCU225, © Copyright
Page 26 of 44
click the Decimals drop-down box in the highlighted row and select 0, 1, 2, or
3 decimal places.
• Shelf Life
To select the length of time the EDR displays the WITS data, click the Shelf
Life drop-down list and choose 5 Mins (minutes), 15 Mins, 1 Hour, 12
Hours, 1 Day, or Never Expires. Once the shelf life period is exceeded, the
EDR changes the value of the trace to null, represented by two dashes (– –).
Important:
Shelf life is an important selection for time sensitive data. The EDR displays the last
received WITS value until the sender transmits a new value, or until it reaches the
end of the shelf life period. WITS data with a long shelf life can be misleading if users
don’t know the data’s age.
5. To enable your custom code to be sent or received, click on the code’s Enable
check box.
6. Click Save > Exit to return to the Setup Menu.
When you are finished, click Save > Exit. The EDR can now receive the custom WITS
code. To send this code, follow the directions in Selecting Custom WITS Codes to Send
below.
You can return all custom WITS settings to default at any time by clicking the Factory
Reset button.

Selecting Custom WITS Codes to Send
After you have set up a custom WITS code, follow the steps below to instruct a Pason
computer to send the code.
1. From the EDR main screen on the RMPC, click Menu > Setup > WITS. The
WITS setup screen opens.
2. On the WITS out tab of the Pason computer you want to send the custom WITS
code, click the Custom button.
3. From the Transmission drop-down list, select the transmission type for the
custom WITS group.
4. Click the custom code’s Enable checkbox.
5. Click Save > Exit to return to the Setup Menu. The Pason computer starts
sending the custom WITS codes you selected.
Receiving a Custom WITS Code and Sending it as a Different Custom Code
The EDR supports receiving a custom WITS value using one custom code and then
sending it using a different custom code. Use this feature if a third party on the rig is
sending a WITS code to Pason that they can’t change, but that code is unusable by
another party who wants to receive it from Pason. For example, Acme Drive Consulting
could be sending top drive RPM to the Pason system as 4002, but General Directional
Associates needs to get top drive RPM from Pason as 0120.
If you need to do this, follow the steps in Selecting Custom WITS Codes to Send above,
but before you save:
1. Click in a code’s row and delete the WITS code listed. This deletion doesn’t
affect the incoming code—it only prepares you for the next step.
2. Enter the custom four digit WITS code you want to use to send the value. Use a
code that’s different from the existing WITS codes. If the code you enter conflicts
with a current EDR WITS code, the EDR highlights your entry in red and does
not allow you to save your settings.
The example below, on an Operator workstation, shows an incoming custom WITS code
of 4002 ready to be deleted and given a new code used for sending.

4.7 Setting Up WITS Codes for Custom Sensors
The EDR enables you to physically connect and monitor up to 50 custom sensors. If you
enter a name for the custom sensor when you set it up in the EDR’s Custom Calibration
Menu, you can assign it a custom WITS code, which you can instruct a Pason computer
to send.
Follow these steps to set up a Pason computer to send a custom WITS code for a
connected custom sensor:
1. Ensure that the custom sensor is connected, and assigned a name in the EDR’s
Custom Calibration Menu.
2. From the EDR main screen on the RMPC, click Menu > Setup > WITS. The
WITS setup screen opens.
3. On the WITS out tab of the Pason computer you want to send the custom WITS
code, click the Custom button.
4. Scroll down to the Custom Analog Port section. You should see the name of the
custom sensor listed.
5. Click in the custom code’s row. The EDR highlights the row.
6. Click under Code in the highlighted row, and enter a four digit WITS code.
Ensure that the code is different from existing WITS codes. If the code you enter
conflicts with a current EDR WITS code, the EDR highlights your entry in red and
does not allow you to save your settings.
7. Select a transmission type from the Transmission drop-down list.
8. To enable the selected Pason computer to send your custom code, click on the
code’s Enable check box.
9. Click Save > Exit. The Pason computer starts sending the custom WITS codes
you selected.
Note:
If you do not see any custom sensors listed in the Custom Analog Port section, ensure
that you assigned your custom sensor a name in the EDR’s Custom Calibration Menu.
The EDR will not list any custom sensors in the Custom Analog Port section unless you
have assigned a name to at least one of them.

4.8 Sending WITS 01 Codes to the EDR
The EDR can receive the WITS 01 codes noted in the Default Pason WITS Codes table
on page 32, but it’s an advanced EDR feature that you need to use with caution.
Before you set up the EDR to receive WITS 01 codes, think about these important
points:
• Contact your Pason representative for assistance before you set this up. If
not properly configured, WITS 01 code data can cause the EDR to display
incorrect values and negatively impact other applications.
• You’ll find the WITS in All tab on the WITS setup screen in the EDR (Figure
14).
• The EDR receives diff. pressure on code 0150 (even though it sends diff.
pressure on code 0171).
• If you send diff. pressure to the EDR, you must also send standpipe pressure
(0121).
Figure 14: WITS in All tab
4.9 Sending Gamma and Gamma Lag Calc
When sending Gamma (code 0824) and Gamma Lag Calc (code 0821) data to the EDR,
make sure you meet these packet and frequency requirements:
Revised May 1, 2019
Revision 25 of DOCU225, © Copyright
Page 31 of 44
• Send both codes in the same WITS packet. Problems occur when Pason
receives one or the other, but not both.
• Send the packet at a minimum 0.2 m (1 ft) interval.
A well-formed gamma packet looks like this:

4.15 Using the WITS Monitor
Starting in EDR version 14.12, the EDR includes a WITS monitor (Figure 16). The WITS
monitor is a simple diagnostic tool included in the EDR on every Pason Workstation. It's
intended for rig personnel who have a good understanding of WITS and packet
communications. Use it to troubleshoot WITS issues at the rig.
To access the WITS monitor, follow these steps from the EDR main screen on any
Pason Workstation:
1. Click Menu > Setup > WITS. The WITS setup screen opens.
2. Click the WITS Monitor tab.

3. In the table at the bottom, click to select the connected device you want to
monitor—look for the workstation type in the Runmode column. Or, to find the
specific IP address of the connected device, type ipconfig on the connected
device’s command prompt screen. Use the IP address displayed at the top of the
command prompt screen to find the device on the WITS monitor screen.
The EDR starts displaying the packet information in the WITS In and WITS Out
boxes.
4. Select Raw or Interpreted in the Format box. The Raw format gives you only
WITS packet information; the Interpreted format adds more detail as shown in
Figure 16 below.
5. Select Disconnect if you want to choose a different device to monitor.
6. Click Exit to return to the setup screen.

Tip:
Use the times logged on the WITS monitor to determine WITS transmission rates. The monitor
displays WITS packets in the order the EDR receives or sends them.
Note:
If a Pason technician needs to troubleshoot WITS communications using CommEngine log files,
they can use the Port and Port Name details to identify the CommEngine to work on. Each WITS
device is represented by its own CommEngine process. WITS CommEngine troubleshooting
information is available to Pason personnel in KBase 1125 Debugging WITS Data Using
CommEngine Log Files.

5 About WITS Port Pin-Outs
This section contains pin-outs to guide you as you design a product interface that is
compatible with the Pason system. Consult the information below if you are connecting a
third-party device that uses RS232 or RS422 communications.
5.1 RS232 Port Pin-Outs
Pason provides two communications boxes for use by third parties interested in setting
up WITS communications between an RS232 device and the EDR system: COMM022
and COMM018. Both of these comm boxes convert RS232 to RS422, which the EDR
can accept.

5.2 RS422 Port Pin-Outs
Conversion via a communications box is not required if your third-party device has
RS422 communication, because RS422 communication is what the EDR accepts. You
can use a cable to connect your device directly to the RS422 port on a DHC or SideKick.
Note:
Be aware that not all RS422 ports are powered.
The RS422 ports on the DHC and SideKick have the following properties:
