h3. A. Cards and connectors ----
You can use 3 different capture cards to record your multistream material on your Galicaster Mobile unit. Depending on the scheme you are about to use, you have to combine different inputs.
The Galicaster Mobile Unit comes equipped with different inputs to fulfil your needs on recording multistream material. Depending on the devices you are about to use you should combine those inputs properly.
* VGA grabber: Epiphan VGA2USB LR
* SDI capturer: Blackmagic Decklink SDI
* NTSC capturer: Hauppauge PVR-350
* SDI capturer: Blackmagic Decklink SDI
* NTSC capturer: Hauppauge PVR-350
There are two main combinations, depending on the type of camera (NTSC or SDI) you use to record the presenter. In both cases you have to use a VGA grabber to record the slides. Those combinations will be explained briefly on the next two sections.

Once you have chosen which devices to use, you need to connect your camera to the Blackmagic Card (SDI) or to the Hauppauge card (NTSC / PAL ). Apart from that, remember to connect the monitor to the graphic card output, not to the motherboard.

If you have a OC-Matterhorn running you have to ask your Matterhorn system administrator for some information. First of all, you need a *digest user* - a regular one won't work-. There is a default digest account that should be replaced with your own values.
First of all, You need the admin host address, including the port. For example:
{code:none}
username: matterhorn_system_account
password: CHANGE_ME
password: CHANGE_ME
host = http://fakeadmin.matterhorn.com:80
{code}
You need the admin host address, including the port. For example:
You also need a *digest user* - a regular one won't work. There is a default digest account that should be replaced with your own values.
{code:none}
host = http://fakeadmin.matterhorn.com:80
username= matterhorn_system_account
password= CHANGE_ME
password= CHANGE_ME
{code}
You also need to set up a default workflow and its parameters. Scheduled recordings will have his own workflow and parameters, defined in the scheduling operation, but the recordings started manually won't. The usual parameters you have to set up are *captions* and *trimHold*, which default to *False*. The normal configuration is:
...workflow-parameters = trimHold:true
{code}
{code}
This piece of code must be written on one of the configurations file. Be aware that values in _conf.ini_ will overrule its equivalent in _conf-dist.ini_.
