4.3.4 USB Interface (ID ISC.MRU200-USB)

The USB socket on the board is terminal X8. The pinout is standardized. The data rate is reduced
to 12 Mbit (USB full speed). A standard USB-cable can be used.
Note:
The length of the USB-cable can be a max. of 5m (20 inch). It is not allowed to use longer
cables.

4.4 Inputs

The optocoupler inputs in Terminal X5 are galvanically isolated from the Reader electronics and
must therefore be externally supplied. The input LEDs for the optocouplers are switch internally
with a series resistor R

Fig. 4-7: Internal and possible external wiring of the optocoupler inputs
For supply voltages of greater than 10 V the input current must be limited to max. 20 mA by an
additional external series resistor (see Table 4-8).
