These pro- ducts are suitable for operation in harsh electrical environments 1 INTERNAL 400k PULL-UP RESISTOR ON EACH TTL/CMOS INPUT. 2 INTERNAL 5k PULL-DOWN RESISTOR ON EACH RS-232 INPUT. and are compliant with the EU directive on electromagnetic Figure 1. compatibility (EMC) (89/336/EEC). The level of emissions and charge pump, all transmitters, and three of the five receivers are immunity are both in compliance. EM immunity includes ESD disabled. The remaining two receivers remain active, thereby protection in excess of 15 kV on all I/O lines (IEC 1000-4-2), allowing monitoring of peripheral devices. This feature allows fast transient burst protection (IEC 100044), and radiated the device to be shut down until a peripheral device begins immunity (IEC 1000-4-3). EM emissions include radiated and communication. The active receivers can alert the processor, conducted emissions as required by Information Technology which can then take the ADM213E out of the shutdown mode. Equipment EN 55022, CISPR 22.
