DD-5100
In this configuration user sees video only from that doorphone, which is connected with his/her monitor. For
example first DD-5100, configured as H type and NET1 configuration selected, is mounted at the gates of closed
yard, second DD-5100, configured as L type and NET1 configuration selected, is mounted at the entry to stairway.
Guest, using H type DD-5100 at the gates, can call to any Flat thru L type DD-5100, but only audio conversation is
possible. See 5.2.1 “
for how to use DD-5100 in NET1 configuration. Although video conversation is possible
from DD-5100 at the entry to stairway (L type configured DD-5100). If video conversation from both DD-5100 is
needed, it is recommended to connected doorphones in a NET through DDSV1 module as shown in fig. 9. In this
case network configuration should be disabled in DD-5100 settings. Although video line from two doorphones in
NET1 configuration (fig. 6) could be connected to audio / video line in parallel, but for long video cables video
performance could suffer.
If more than two doorphones needs to be connected to a network, one DD-5100, configured as H type and
either NET2 or NET3 configuration selected, and as many as 9999 DD-5100's, configured as L type doorphones
with NET2 or NET3 configuration selected, could be used as shown in fig. 7. In fig. 7 shown wiring diagram has
drawback - user in a flat can't see guest at H type doorphone. To overcome this drawback it is recommended to
connect several DD-5100's in network through DDSV1 commutators as shown in fig. 10. In this setup, any network
configuration for all DD-5100's should be turned off in settings menu. In wiring diagram in fig. 10 is depicted
network implementation for object, which includes gates of the closed yard and three entrances at the stairways.
In case more than two H type DD-5100's needs to be connected to network, H type DD-5100's should be
connected through network module DD-S2.1, as shown in fig. 8. If several DD-5100's should share the same audio
line, network commutator DD-S2.1 or DDSV1 (for audio / video line) could be used, as shown in fig. 9. This is
useful when one building has several entries. Commutator itself could be connected to H type DD-5100 as one of L
types.
Example 1:
there is a yard with three houses, each of them has two entrances. The yard has gates. Video
conversation should be possible from DD-5100 at the gates and DD-5100 at any of the entrances, to any flat of
corresponding house.
Solution:
replace all L type DD-5100's in fig. 8 (with all devices connected to audio / video line, electric lock
etc.), with complete schematic of fig. 9. Then one of the two L type DD-5100's should be connected to H type DD-
5100 in parallel (Line of H type DD-5100 should be connected to L-IN of one of the two L type DD-5100's). Now
each house has two DD-5100's which share one audio / video line. One L type DD-5100 for each house (total
three) are connected to H type DD-5100 at the gates. Configure one DD-5100, at the gates, as H type NET2 or
NET3 and three DD-5100's, at the entrances, as L type NET2 or NET3, see chapter Chapter 5. “

Network configuration for remaining three DD-5100's should be disabled.
