SATELLINE-M3-R3 User Guide, Version 1.2 1.3 DTE connector DTE connector is 20-pin pass-through connector. This connector allows the pin to enter the connector from the bottom side and protrude thru the module PCB to the top side, allowing flexible mounting heights with various pin lengths. Entry from bottom of device, see picture below. Side view of the module with 1.27mm pitch connector and screw fixing. Pin numbering of 1.27 mm pitch DTE connector.

SATELLINE-M3-R3 User Guide, Version 1.2 3 CHANGING PARAMETERS USING SL-COMMANDS The controlling terminal device can change the configuration settings of the module. This is accomplished with the help of SL-commands, which can be used during data transfer. SLcommands can be used to change e.g. the frequency or addresses. It is also possible to ask the radio modem to show current settings which are in use.

SATELLINE-M3-R3 User Guide, Version 1.2 PS-mode Receiver ON/OFF 1. When started, 7 messages are analyzed and the average is calculated. The ON/OFF interval (plus some margin) is selected according to the shortest and modem is switched OFF. Modem will be switched on 60ms prior to next message. 2. The interval is measured all the time from every message. 3. If the interval is shorter than 10ms from average, additional 1ms is added to the average value. 4.

SATELLINE-M3-R3 User Guide, Version 1.2 3.5 Turn ON using command When being in either off or sleep mode, the modem will be automatically wake up after the CPU senses a state change in the TD1 pin. The first data byte is lost because the CPU UART is shut off, and is not able to read data.

Time (* Explanation Tvic 0 >50µs When voltage is applied to VCC_IN the filter Input capacitor charge time capacitors inside the module are charged, creating a small current surge. If the feeding power supply is not very strong it is recommended to wait this time before rising ENA_MODEM to minimize current surge.

SATELLINE-M3-R3 User Guide, Version 1.2 3.12 Stat pin The STAT pin indicates the status of the device. It can be used to drive a LED using a series resistor. STAT pin drive capability is 10mA (loads the VCC_IO if provided externally). The STAT pin has the following behavior. Blink cycle “1” - statically “0” for the endurance of the received frame.

SATELLINE-M3-R3 User Guide, Version 1.2 6 CONSIDERATIONS 6.1 Emi Interferers The module is designed to be mounted inside a host device. The module is designed to withstand EMI even beyond type approval requirements. However, a small module which is integrated closely to modern high speed electronics is bound to receive some interference. To make a working integration consider the following.

SATELLINE-M3-R3 User Guide, Version 1.2 6.2 Electrostatic discharge As the module is intended to be embedded in a host application, in a typical use case, the antenna port is the only port of the module directly interface with a surface or contact area subjected to Electrostatic Discharge (ESD). Thus, the antenna port is the only interface with high level ESD protection.
