Chapter 6. Appendices

6.1 Appendix A - Connector pin-outs

6.1.1 Power

This is a standard 4-pin “mil-spec” plug, conforming to MIL-DTL-26482 (formerly MIL-C-26482). A typical part-number is 02E-08-04P although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***-08-04S and are available from Amphenol, ITT Cannon and other manufacturers.

6.1.4 Antenna

This is a standard female SMA connector conforming to Military specification sheet MIL-C-39012. They are very widely available, as are suitable mating connectors.

6.2 Appendix B - Using terminal emulators

There are a number of terminal emulator programs that you can use to access the serial ports of the modem. Güralp recommend the use of PuTTY on Windows PCs and picocom on Linux PCs. These are detailed below.

6.2.1 Using PuTTY.

PuTTY is a free terminal emulation and ssh package for windows. It can be downloaded from www.chiark.greenend.org.uk in a number of different packages. The easiest package to use is the 'windows installer'. Install PuTTY by following the simple on-screen instructions.

6.2.2 Using picocom for linux

Picocom is a simple terminal emulation program for linux. More information on picocom is available at http://linux.die.net/man/8/picocom

6.3 Appendix C – Configuration reset

It is possible to restore all configuration parameters of the GPT (including the administration password) to their factory default settings.

Caution: ESD: The circuit board within the GPT includes components which can be damaged by electrostatic discharge. Always work on a properly grounded dissipative surface and wear a suitable grounded wristband. Ground yourself by touching an earthed conductor before handling the circuit board.

Note that all configuration changes that you have made will be lost and the unit will need re-configuring.
