Techsol's Communications Gateway Products

Techsol is a world leader in Linux on ARM technology. The Gateway product line is a collection of low-power, embedded computers that are rich with communications capabilities. Gateways either include a Medallion Computer Module or they incorporate the same Hardware Platform enabling them to leverage Techsol's vast Software expertise and features.

Gateway Power

Power can be applied at the power-jack, or at the RJ-12 connector for the RS-485 signals.
To enable the latter feature, a jumper must be installed inside the unit in the area of the power-supply. (this is a plain "shunt" connecting 2 pins that are 0.025" square and centered 0.100" apart)
Power is received from pins #1 and #6 of the RJ-12 connector.
Ground is on pins #2 and #5.
Data signals are on the middle pair (as in all telecom-type connectors) specifically pins #3 and #4.
