ST 6000 - HARDWARE GUIDE
1 OVERVIEW
The ST 6000 provides a high performance, low latency, two-way communication solution that uses the IsatData Pro
network.
The device consists of a Lua application controller, integral antennas, a satellite modem for communicating with the
satellite, an integral GNSS subsystem, several input/output feeds capable of monitoring and controlling external
sensors and devices, and dedicated serial ports (two RS-232 ports and an RS-485). Solution Providers (SPs) must
create a custom power supply for their particular application.
Figure 1: ST 6000
The ST 6000 is suitable for both industrial and fixed applications, and it can work as a standalone data-messaging
device, with built-in I/O data collection and processing capabilities. Feature-rich software tools make programming
easy and shorten the design and testing time.
1.1 Key Features and Benefits
The ST 6000 has the following key features and benefits:
lDesigned to be incorporated into a custom solution
lBuilt-in GNSS receiver to calculate position, speed, and heading that uses the satellite antenna
lBroad operational temperature range
lIsatData Pro message payload and latency capabilities

Note: Integrators who integrate ST6000 OEM module into their final products should follow FCC and IC labeling rules
to indicate the final product "CONTAINS FCC ID: XGS-ST6000 and IC ID: 1181A-ST6000" on product label. In some
cases, If the regulation is applied, Integrators may need to get their own FCC ID and IC ID for the final product.
Anatel
Anatel certification and test results are available to Solution Providers for use as a baseline for the certification
approval of their ST 6000 enclosure.
In all cases, the SP is responsible for ensuring that their final ST 6000 enclosure complies with all local regulatory,
electrical and safety codes. As the ST 6000 enclosure contains the SP's power supply and possibly other circuitry that
affects the ST 6000, likely additional testing or a repeat of some of the tests listed below may be required.

3.3 Power
3.3.1 Input Power
The ST 6000 has two power input pins (VAUX and VIN), and can be powered from either a single or dual external DC
power source.
VAUX supplies power to the ST 6000 baseband and RF processors. Regulated power must be applied to this pin
continuously to keep the device alive and synchronized with the satellite network.
VIN is the input power pin for the RF power amplifier circuitry. Regulated power must be applied to this pin whenever
the device drives the TX_PWR EN line high and may be removed when the TX_PWR EN line is low. Alternatively, power
may be applied to this pin continuously and TX_PWR_EN ignored.
Note: Input power protection is not provided on the ST 6000.

3.3.3 Inrush Current
Inrush current transients occur when the ST 6000:
lFirst powers on
lWakes up
lApplies power to the RF transmit circuitry
These transients are of very short duration and low energy but can have high peak currents. The power supply must
be capable of handling these inrush currents without dipping below the minimum input voltage of the respective
power rails. Typical inrush currents are listed in the following table.

3.4 Input/Output
The ST 6000 I/Os are each independently operable and configurable in one of the following modes:
lAnalog input
lDigital input
lDigital output – push pull
The ST 6000 is equipped with various I/O ports. Refer to the pin number descriptions in section 3.1.5 for an
explanation of each I/O signal. To connect these ports to an external device you may need to use a suitable translator
depending on what the signal is connected to.
The I/O electrical characteristics of this interface are shown in Table 7 and Table 8 shows the analog characteristics.

3.4.1 Input Bandwidth
When used as a digital or analog input, the bandwidth of the I/O circuitry is 1 kHz or more.
Note: This does not imply that the software must have a sample rate greater than 1 Hz.
3.4.2 Output Bandwidth
When used as a digital output the I/O circuitry has a bandwidth exceeding 100Hz.
Note: This does not imply that the software must have the capability of generating high rate pulse trains at
frequencies > 10 Hz.
3.5 Serial Interfaces
The ST 6000 is equipped with various serial ports. To connect these ports to a standard RS-232 serial device such as
a computer for example, you must use a 3.3 V TTL/CMOS to RS-232 translator device.
The electrical characteristics (Table 9) of the interface are:
Table 9: Electrical Characteristics
Parameter Min. Typical Max. Units
Rx input high voltage threshold 2.31 V
Rx input low voltage threshold 1.155 V
Tx output high voltage threshold 2.8 V
Tx output low voltage threshold - 0.5 V
3.5.1 Console/Auxiliary (RS-232) Interface
The ST 6000 is equipped with an RS-232 console and an auxiliary TTL level serial port. The auxiliary port is primarily
intended for debug output or software upgrade downloads. The console and auxiliary serial port is connected directly
to the UART of the microcontroller and therefore communicates via CMOS level RS-232 style signaling (0-3.3 V, non-
inverted).
The console and auxiliary serial interfaces to the ST 6000 are asynchronous with 1 start bit, 8 data bits, no parity, 1
stop bit; the default rate is 9600 bps, while the maximum rate is 115.2 kbps. The interfaces are 3.3 V TTL compatible.

3.5.2 RS-485/J1708 Interface
The ST 6000 has a dedicated TTL level serial port for interfacing to an RS-485/J1708 interface as an accessory bus
and for SCADA interfacing. The ST 6000 does not incorporate a driver and termination resistor. The RS-485 serial port
is connected directly to the UART of the microcontroller and therefore communicates via 3.3 V CMOS levels.

ST 6000 - HARDWARE GUIDE
Figure 5: Accelerometer Axis
The accelerometer is very important for low power devices when it is critical to save power while stationary and
quickly detect when motion starts. In powered devices where low power is not critical, GPS can be polled to detect
motion. However, for low power applications frequent GPS fixes can dominate the power budget. To reduce power
budget effects of GPS fixes, an accelerometer can be used to trigger a GPS fix to detect if motion occurred.
The accelerometer thresholds to detect motion vary depending on the environment. In order to avoid, false motion
detects, extensive testing is required to ensure that adequate acceleration magnitude thresholds and time durations
are used. Refer to [T405] for further details about the accelerometer.

4 INTEGRATION GUIDELINES
This section contains a number of guidelines to assist the Solution Provider (SP) in building their ST 6000 enclosure.
It must be recognized that this section provides guidelines only and each SP must use their own discretion to finalize
the integration approach that works for them.
4.1 Enclosure Design
The ST 6000 is not designed for outdoor environments. Consequently, the ST 6000 requires a robust
environmentally sealed enclosure that can house the ST 6000.
The following guidelines are recommended for the enclosure design.
lAn IP67 rating or better for outdoor use.
lUse enclosure materials that are transparent to L-Band (1-2 GHz) radio signals.
lTwo recommended enclosure materials are:
lXenoy®Resin 5220U. This plastic material offers good chemical and UV resistance and great impact
resistance even at low temperatures.
lLexan EXL 9330.
4.2 Ground Plane Requirements
A metal plate is required under the antenna board. The optimal recommended separation between the metal plate
and the modem card is 0.86”. This can be reduced to 0.5” with some moderate impact on low elevation gain.
If the ST 6000 is installed on a metal surface larger than the metal plate size indicated in Figure 9, then no metal plate
is needed as long as the surface-to-antenna distance is the same as shown in Figure 9.

4.3 Labeling
The mobile ID on the ST 6000 is the network identification number. It is recommended that the SP place a copy of
the mobile ID on the exterior of the enclosure housing the device. With the mobile ID on the enclosure, installers can
readily identify the network identification number.
