‘Camera’-Interface (not for NetCamPlus)
The second serial interface is labelled ‘Camera’, which is limited to RS232C mode, in
contrast to the previously discussed ’Modem’ interface. The ’Camera’-port is intended
for bidirectional transparent data transmission. The transparent data channel oper-
ates full-duplex and in parallel to video and audio transmission via ISDN. Transparent
