Talkers and Listeners
Do not connect multiple devices outputing data (Talkers) on to
the input (Rx) of the unit. The RS422 protocol is not intended for
this type of connection, and data will be corrupted if more than
one device transmits simultaneously. The output however may
drive multiple receivers (Listeners). The number of receivers is nite,
and depends on the receiving hardware. Typically three devices is
possible.
Video In
On the HDS-9 and HDS-12, a video camera may be added by
installing the optional video adaptor cable between the power
socket on the unit, and the plug on the power/data cable.
¼ Note: The video images will not be shared with another unit via the
network. It is only possible to view video on the unit connected to
the video source.
