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

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.

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.
