Page 7: Purpose
It is designed to transmit either AES 256-bit encrypted or unencrypted data (but not voice) via the Iridium satellite network. Similar to a standard landline modem, the A3LA-RG can be controlled by any DTE (data terminal equipment) capable of sending standard AT commands via an RS232 serial port. -

IMPORTANT: Never feed supply voltage into the active GPS antenna. Always use the bias voltage supplied by the A3LA-RG SMA antenna connector to power an active GPS antenna. Feeding voltage to the GPS antenna other than the provided bias voltage will permanently damage the A3LA-RG. -

Appendix A. The factory-set baud rate is 19,200 bps and can be changed using the +IPR command. Note that the Ring Indicator is used by the A3LA-RG to indicate that a Mobile Terminated SBD (MT-SBD) message is queued at the gateway. Application developers can monitor this pin and apply appropriate AT commands to the A3LA-RG to retrieve the MT-SBD message. -

A3LA-RG to malfunction during a data call, an SMS session or an SBD session. Power reset by the A3LA-RG during a call is an indicative of the DC power source unable to sustain voltage above 4.0V at peak current demand. Appendix E provides the electrical power profile of the A3LA-RG. -

With the A3LA-RG held in the position shown in Figure 2 (DB25 connector to the left), the A3LA-RG is set for 4.0V to +5.4V when the red jumper is on the middle and left pins and is set for +5.0V to +32V when the jumper is on the middle and right pins. Each pin is also labeled with 5V and 32V to the left and right pins, respectively. -

20) enable an analog audio handset to be connected to the A3LA-RG. With the DPL audio handset model DPLS0401-X and DB25 data kit model HRC-24-8R, the A3LA-RG can be used both as a data modem and a satellite phone. This setup as shown in Figure 3 can be an extremely useful developmental tool since the modem status can be seen on the handset LCD similar to a 9555 Iridium phone. -

If the reading is near the decision threshold it would be easy to see a 1 bar difference. 6.0 GPS ANTENNA CONNECTOR The A3LA-RG modem uses an SMA female connector for the GPS antenna (Figure 4). Any active antenna required a bias voltage of ~3.3VDC with <50mA is appropriate. NAL Research offers a magnetic mount GPS antenna as well as dual Iridium/GPS antenna for use with the A3LA-RG. -

10.0 MODES OF OPERATION The A3LA-RG serial data port is always in one of two modes: command mode or data mode. When the data port is in command mode, AT commands can be entered to control the A3LA-RG. In command mode, flow control has no effect, with the RTS input ignored and the CTS output driven ON (low). -

The 9523 RF board can sometimes ‘lock-up’ when being inactive over a long period of time (a day or longer). The only way to recover is to power cycle the ISU. The A3LA-RG has safeguards put in place with a watch-dog timer to keep the 9523 RF board from locking up. -

^MPTFP command. 13.0 MOUNTING RECOMMENDATIONS The A3LA-RG has four features on its bottom surface that can aid in its mounting (see Appendix J). These four features are pre-drilled at a minimum depth of 0.25 inch to accept 6-32 thread type. -

Some basic commands listed in this document are marked with “No action, compatibility only”. In these cases, the basic command is accepted in the same fashion as is with other modems, but has no effect on the operation of the A3LA-RG, since it has no meaning in the Iridium environment. - Page 19 A.5 Command Entry An AT command is a string of characters sent by the DTE to the A3LA-RG while it is in command mode. A command string has a prefix, a body, and a terminator. The prefix consists of the ASCII characters AT or at.
- Page 20 Result codes can be represented by text if the A3LA-RG is in verbose mode or with numbers if in numeric mode. The command ATVn informs the A3LA-RG whether to respond in verbose or numeric mode.
