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.
