EP5101 - Interface signal level
In differential mode, the EP5101-x00x expects signal levels according to RS422. The data are transferred
without ground reference as voltage difference between two cables (signal A and inverted signal /A). The
module analyses signal levels in the range -200mV < Vid < +200mV as valid signals. The differential signal
must be in the common mode range (<+13.2 V and >-10 V, with respect to GND) (cf. diagram). Signal levels
outside this range can lead to destruction
Fig. 75: EP5101 signal level interface
In differential mode only the voltage difference is evaluated, so that common-mode interference on the
transmission link does not lead to corruption of the wanted signal, since any interference affects both cables
simultaneously.
If the EP5101 is only operated in single-ended mode, a nominal level voltage between 3.5 V and 5.5 V is
expected.
For the EP5101-x00x versions, open circuit detection is typically enabled in the range -1.5 V > Vid > +1.5
(subject to change).
