RS422
One of several standards that incorporate balanced line signals into DB connectors. A pair of wires is used to carry each signal. The data is encoded and decoded as a differential voltage between the two lines. (www.sangoma.com)

Fixed Area Hydrogen Monitor
HY-ALERTA™ 600B
-
H2scan’s HY-ALERTA™ 600B Fixed Area Hydrogen Monitor will provide hydrogen-specific leak detection and measurement for hydrogen concentrations as low as 4000 ppm and can be scaled to any concentration up to 5% hydrogen by volume, a range representing 10% to 125% of hydrogen’s low flammability limit. They are designed for either ceiling or wall mount and have RS422 capability that extends the interface from the sensor to the controller to several hundred feet. H2scan’s hydrogen-specific sensor technology has no cross sensitivity to any other combustible gases, thus eliminating false positive alarms and increasing system reliability.

Protocol Converter
MACC
-
When designing or upgrading avionics systems we are often faced with the task of integrating components that were not originally designed to work together.A control computer that communicates using RS-232 may need to control component that expects MIL-STD-1553 messages or an INS may put out ARINC-429 labels, which are needed by Multi function Display designed around RS-422.Faced with problems like these, integrators must choose between two poor options. They must either give up on one of the units in favor of another unit that may be less suitable but uses the appropriate communications spec; or they must add a computer system – often PC104 – which can translate from one unit to the other. These computers are generally large, heavy, hot, and require substantial power.
