SAT130/SAT140

The SAT130 is provided as an off-the-shelf kit that has the following components: SAT130 Terminal, CBL-SAT130-TB2 Breakout Box, Flex Cable. The SAT130 Kit is a convenient method of connecting your devices to the SAT130 Terminal. The SAT140 is similar to the SAT130 but supports 4G cell whereas the SAT130 support 3G.

See SAT130/SAT140 Product Page for more details.

SAT130 Terminal

The SCADALink SAT130 is a versatile low-power satellite, cell, ethernet, and wifi 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 1).

Onboard I/O Wiring Examples

Call outs to a cell network will fail-over to the satellite network.

Flex Cable

The cable is a flexible 10 pin multiconductor molded cable house in SEALTITE® flexible liquid-tight conduit. Either the RS-485 can be configured or the RS-232 but not both at once. The configuration is determined by jumpers.

Color Wire Gauge GPIO Pin Function

Orange 22 AWG 15 RS-232 Tx
Yellow 22 AWG 3 RS-232 Rx

GPIO

The general purpose I/Os are available on an 18-pin Molex Micro-Fit 3.0™ connector, labelled as “GPIO” on the front panel. There are two configurations for RS-485 and RS-232. The most common configuration is RS-485 and is the Bentek default configuration.

Jumpers

Jumpers on the Telematics card determine the configuration of the external I/O connector. These are normally set by Bentek systems before the SAT130 is delivered.

Onboard I/O

The SatSCADA GUI can control four onboard I/O pins. These are called 'ports' and are in the range 1 to 4. These ports are also in the internal register map and are identified by these port numbers. See the SatSCADA GUI Onboard I/O form for more details.

The mapping between these port numbers and the physical pins is:

Port Digital Input Digital Output Analog Input
1 input1 output13 input1
2 input2 output14 input2
3 input3 N/A input3
4 input5 N/A input5

The analog inputs are all in the range 0 to 3.3 V. The readings have a resolution of .7 mV since the hardware has 12 bits. These 12 bits are mapped to be in the range from 0 to 32767 by software.

Installation and Setup

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 SAT130 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 call out on low and high power supply voltage.  By default, the unit is configured to call out 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 SAT130 has two serial ports that can be used to connect to field equipment: COM0 and COM1. COM0 is an RS232 port and COM1 is an RS485 2-wire port. One or the other can be used in one configuration but not both at once.

I/O: The SCADALink SAT130 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 SAT130 GUI to operate in any of these three modes.

These images show a typical configuration that is available and how to wire.

Configuring the Terminal

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 SAT130 terminal can be configured locally via ethernet or WiFi using the GUI with an SSH connection.

Remote Configuration: The SAT130 terminal can also be configured remotely over-the-air using the GUI. Internet access to the satscada server is required. Both satellite and cell are supported. The SAT130 can also be configured over direct cell, without acessing the satscada server, using the GUI with an SSH connection. When the satscada server is used sat/cell failover is supported during the configuration process.

Modbus Operation

Modbus Slave: The SAT130 can operate as a Modbus RTU Slave via the RS232 or RS485 ports or over the air.

Modbus Master: The SAT130 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.

Install the SIM Card

The terminal does not ship with SIM card. To use the cellular capabilities of this terminal you must purchase, activate, 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.

  1. Disconnect the power connector from the power source.
  2. Remove the four screws2) from the panel containing the power connector and reset button. Remove the panel once you have removed the screws.
  3. Push and release any existing SIM card to remove it from the SIM holder.
  4. Insert the SIM card, circuit down and the notch facing away from you and to the left.
  5. Push gently until the card is all the way in and listen for a click to make sure it is securely in place.
  6. Replace the panel and use the T6 screwdriver to tighten the four screws.
  7. Check the cell LED on the terminal to see that it is flashing green. If it is not, contact your cellular data solution provider to ensure your SIM card is operational.
