Mezzanine System
5033
System
ECM P/N 5033 provides eight channels of RS485 / RS422 I/O. The 110 ohm termination for each channel is enabled or disabled in software. Disabling termination saves power by eliminating unneeded or redundant termination. Speeds of up to 20 Mega bits per second are possible, but this design also features a 250K bits per second slower edge rate mode. The 250K bit mode is valuable when EMI is more of a concern and throughput is not important. All channels power up as inputs with the outputs disabled.

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.
