Transmitter Performance Characteristics
Receiver Performance Characteristics
Power supply and grounding: The power supply line should
be well-filtered. All 0.1 µF power supply bypass capacitors
should be as close to the DTR transceiver module as possible.
The two front GND posts (mounting studs) should be
grounded to Chassis Ground for best EMI and ESD protection.
If Chassis Ground is not available, they should be tied to
Circuit Ground.
