|
Please also see the [Buildup Plan](buildup.md) for detailed instructions and what to consider when setting up a lecture room.
|
|
|
|
The 2 main components of the lecture hall setup are the lectern module on the stage and the FOH module and camera at some "front of house" location.
|
|
They are connected by: 1 SDI cable and 1 ethernet cable.
|
|
Depending on the location of the audio inputs to the hall, one or two XLR cables may also be laid to the stage or some other location in the hall.
|
|
Considerations regarding network connection can be found in the [Network Setup](#network-setup) chapter.
|
|
|
|
This cabling diagram contains all connections between modules and devices (but not the inner workings of the modules): 
|
|
|
|
## Network Setup
|
|
|
|
A VOC lecture hall setup needs some internal VOC network (commonly named VOC-VLAN, even though it may not always be a VLAN technically) and a way to have internet access.
|
|
Depending on the number of rooms and the network provided by the location or event there are multiple ways to connect rooms.
|
|
This needs to be designed by the VOC responsible person.
|
|
|
|
The easiest setup is a single room (or multiple fully independent rooms).
|
|
Since the Lectern and FOH modules both have network ports for public and VOC network and a VLAN trunk between them, it doesn't matter where the public network is connected.
|
|
|
|
### Recommended Single-Room Network Setup
|
|
|
|
- Put the WRT router near the FOH module
|
|
- If the room's public network (uplink) is located at the stage:
|
|
* Connect the public network (uplink) to the "public" port of the lectern module
|
|
* Connect the WAN port of the WRT to some "public" port of the FOH module's network switch
|
|
- If the room's public network (uplink) is located near the FOH:
|
|
* Connect the WAN port of the WRT to the public network (uplink)
|
|
- Connect one LAN port of the WRT to some "VOC" port of the FOH module's network switch
|
|
- Power on the WRT router
|
|
|
|
See <https://c3voc.de/wiki/hardware:wrts> how to enable DHCP in the VOC-(V)LAN if needed.
|
|
|
|
### Multi-Room Network Setup
|
|
|
|
Ideally there's a private VLAN between all rooms which can be used to interconnect all room setups and the office.
|
|
In that case, each hall setup just needs to be connected to the venue VLAN with one "VOC" port (either at the lectern or at the FOH module -- whatever is more convenient).
|
|
|
|
When the server case is used, the router VM will provide uplink to the whole VOC network.
|
|
If not, deploy one WRT router in a lecture hall or the VOC office providing a connection between public and VOC network.
|
|
(Remember to enable all hall networks which are reachable via this router so that the remote access VPN works. TODO: Where is this documented?)
|

|
## FOH Module
|
|
|
|
|
|
|
|
See the netbox for detailed port configuration:
|
|
[Case 1](https://netbox.c3voc.de/dcim/devices/19/interfaces/),
|
|
[Case 2](https://netbox.c3voc.de/dcim/devices/25/interfaces/),
|
|
[Case 3](https://netbox.c3voc.de/dcim/devices/26/interfaces/),
|
|
[Case 4](https://netbox.c3voc.de/dcim/devices/27/interfaces/),
|
|
[Case 5](https://netbox.c3voc.de/dcim/devices/28/interfaces/),
|
|
[Case 6](https://netbox.c3voc.de/dcim/devices/29/interfaces/)
|
|
|
|
## Lectern Module
|
|
|
|
|
|
|
|
|
|
Use ethernet connections at the front unless a fiber trunk is needed via the SFP slots.
|
|
|
|
Otherwise see the netbox for detailed port configuration:
|
|
[Case 1](https://netbox.c3voc.de/dcim/devices/30/interfaces/),
|
|
[Case 2](https://netbox.c3voc.de/dcim/devices/31/interfaces/),
|
|
[Case 3](https://netbox.c3voc.de/dcim/devices/32/interfaces/),
|
|
[Case 4](https://netbox.c3voc.de/dcim/devices/33/interfaces/),
|
|
[Case 5](https://netbox.c3voc.de/dcim/devices/34/interfaces/),
|
|
[Case 6](https://netbox.c3voc.de/dcim/devices/35/interfaces/)
