SDT16 Family Installation and Configuration Guide
2 Chapter 1. Getting Started
Bullhorn System Overview
Bullhorn is a wireless, telemetry system that provides scheduled and by-exception inbound
reporting for field equipment that is typically located in remote areas. Based on the type of
Bullhorn unit you are working with, data and alarm packets transmit from remote field locations to
your account on the secure, Bullhorn website using digital cellular or satellite communication
networks. You can quickly determine the status of field equipment anytime by using information
posted to your account on the Bullhorn website (http://www.bullhornsys.com).
Bullhorn units provide remote monitoring with full coverage using GSM digital cellular, GEOS
satellite (SkyWave-Inmarsat), or LEOS satellite (ORBCOMM) communication networks.
SDT16 Family Overview
The SDT16 family includes the SDT16-GSM, SDT16-ORB, and SDT16-SAT unit types. All these
unit types collect and report register readings for equipment (such as a flow computer) located in
remote areas; support up to sixteen 6-digit registers, eight 12-digit registers, or a combination of
both; and support the following communication protocols: Modbus ASCII and RTU (master),
Mercury, Dresser, Reynolds 16-bit, and Reynolds 32-bit.
SDT16 units provide serial inputs for receive data (Rxd), transmit data (Txd), and ground (Gnd).
The DTR output (data terminal ready) is used to initiate the handshake signal. If the input device
requires a handshake signal from an SDT16 unit, an optional output for alarm detection and
initiation of a handshake signal is also available. Dry contact closure is used to detect an alarm
condition using the
Chan 1
input on the SDT16.
Unit types in the SDT16 family collect and transmit register readings to your account on the secure
Bullhorn website based on a pre-defined time schedule specified during the configuration process.
The type of unit determines which communication network is used for data transmissions. The
SDT16-GSM transmits data using GSM, digital cellular services provided by KORE Wireless. The
SDT16-ORB uses the ORBCOMM satellite network to transmit data. The SDT16-SAT uses
SkyWave satellite terminals and network services that communicate through Inmarsat satellites to
transmit data. For more information about KORE Wireless or ORBCOMM, refer to
GSM Digital
Cellular Service on page 19 or ORBCOMM Satellite Service on page 21. For more information about
the SkyWave satellite service, refer to SkyWave-Inmarsat Satellite Service on page 20.
For an overview of the harware configuration of the SDT16-GSM, SDT16-ORB, and SDT16-SAT,
see the following three figures (Figure 1-1, Figure 1-2, and Figure 1-3).
