The SAT120 is provided as an off-the-shelf kit that has the following components: SAT120 Terminal, SAT-1xx-TB1 Breakout Box, Flex Cable. The SAT120 Kit is a convenient method of connecting your devices to the SAT120 Terminal.
See SAT120 Product Page for more details.
The SCADALink SAT120 is a versatile low-power satellite and cell terminal. It is a SCADA device that provides Modem, RTU, and Alarm Callout functionality in a single product. It is designed for remote SCADA communications, monitoring I/O and RS232 / RS485 serial devices.
Call outs to a cell network will fail-over to the satellite network.
Each transceiver is a self-contained unit, including satellite transceiver (modem), quad-band cellular modem, GPS, programmable microcontroller, and multiple discrete and analog I/Os (input/output) capable of monitoring and controlling external sensors and devices. Ideal for fixed installations or mobile applications.
The transceiver unit is not waterproof. Use it inside a panel or inside a vehicle, and away from environmental exposure. That is any form of moisture such as rain, snow, or pooled water.
Arranging the transceiver unit’s connectors at one end of the unit simplifies installation. Sturdy flanges on the side make mounting quick and easy.
An anti-tamper SIM door on the back side of the unit provides easy access to the SIM card holder. A mini-B USB connector located next to the SIM door provides a serial port for configuring with the SatSCADA GUI.
The 15’ cable is a flexible 10 pin multiconductor molded cable house in SEALTITE® flexible liquid-tight conduit.

Mounting: The SAT1xx Breakout Box Kit comes with pipe clamps to attach the terminal to a pipe. The included mounting bracket also provides a convenient method for the terminal to be physically screwed onto the side of a building.
Orientation: The SAT120 terminal dome should be installed with a clear view of the sky in the SE direction. If any obstructions are present within the viewing angel of 30 degrees above the horizon, the dome might need to be repositioned for improved clearance.
Power: The unit requires a power supply rated at 10-30 VDC at 5A (peak) for operation.
Alarms: An internal alarm can be configured to callout on low and high power supply voltage. By default, the unit is configured to callout a low alarm at 11.58 VDC and a high alarm at 13 VDC. This can be changed by SCADALink support when the unit is powered with a view of the sky.
Serial Interface: The SCADALink SAT120 has two serial ports: COM0 and COM1. COM0 is an RS232 port and is typically used for configuration but can also be used to connect to field equipment. COM1 is an RS485 2-wire port that is used to connect to field equipment.
I/O: The SCADALink SAT120 provides four onboard configurable I/O pins that operate in any of three modes: Analog Input, Digital Input, Digital Output. Each of the pins can be configured via the SAT120 GUI to operate in any of these three modes.
The terminal will be delivered pre-configured and tested. Updates to the configuration can be done with the SatSCADA GUI application. Instructions are available on this site at SatSCADA GUI.
Local Configuration: The SAT120 terminal can be configured locally using the SatSCADA GUI via by: (a) a straight through serial cable attached to the SAT-1xx-BB breakout box RS-232 connector; or (b) the terminal's Mini-B USB connector attached to a computer's Type A USB connector.
Remote Configuration: The SAT120 terminal can also be configured remotely over satellite or cell using the GUI. Internet access is required.
Modbus Slave: The SAT120 can operate as a Modbus RTU Slave via the RS232 or RS485 ports or over the air.
Modbus Master: The SAT120 can function as a Modbus RTU master through its RS232 or RS485 ports. Registers polled via the Modbus RTU Master function can be mapped to Modbus registers in the terminal.
The terminal does not ship with SIM cards and provides the option of installing a second, optional, SIM card. To use the cellular capabilities of this terminal you must purchase and install a SIM card. Purchase a SIM card, activated for use with a cellular network, from a Service Provider serving the area the terminal operates in. The SIM card must support operation on 1.8 V or 3 V. The terminal does not support 5 V SIM cards.
Never insert or remove the SIM card if there is power to the terminal. This could result in
physical damage to the SIM card.
Red. Indicates that the terminal has external power. This LED is on continuously (solid red) when power is applied.
Yellow. Indicates satellite communications status.

The SAT120 has a Mini-B connector that can be used to connect to a Type A USB port on your laptop. This will appear as a serial port on the laptop. The SatSCADA GUI can be used to connect via that serial port to the SAT120 for the purpose of configuring the terminal.
You will need to have a Mini-B to Type A USB cable. The Mini-B connector is typically used for digital cameras and is not to be confused with the Micro-B that is used on smartphones. You will not be able to use your smartphone cable to connect to the SAT120. See USB Connector Types for more information and diagrams related to this topic.
To connect your laptop to the SAT120 follow these instructions:
