GPIO Pin [1..4] Mode
The four GPIO pins are configured individually. The state can be retrieved by “xStatus GPIO Pin [1..4]
State”. The default pin state is High (+12V). When activated as output, they are set to 0V. To activate them
as input, they must be pulled down to 0V.
Value space: <InputNoAction/OutputManualState/OutputInCall/OutputMicrophonesMuted/
OutputPresentationOn/OutputAllCallsEncrypted/InputMuteMicrophones>
InputNoAction:
The pin state can be set, but no operation is performed.
OutputManualState:
The pin state can be set by “xCommand GPIO ManualState Set PinX: <High/
Low>” (to +12V or 0V, respectively).
OutputInCall:
The pin is activated when in call, deactivated when not in call.
OutputMicrophonesMuted:
The pin is activated when microphones are muted, deactivated when not
muted.
OutputPresentationOn:
The pin is activated when presentation is active, deactivated when presentation
is not active.
OutputAllCallsEncrypted:
The pin is activated when all calls are encrypted, deactivated when one or
more calls are not encrypted.
InputMuteMicrophones:
When the pin is activated (0V), the microphones will be muted. When
deactivated (+ 12V), the microphones are unmuted.

Pin 1 Mode: InputNoAction
H323 NAT Mode
The TANDBERG firewall traversal technology creates a secure path through the firewall barrier, and
enables proper exchange of audio/video data when connected to an external video conferencing
system (when the IP traffic goes through a NAT router). NOTE! NAT does not work in conjunction with
gatekeepers.
Value space: <Auto/On/Off>
Auto:
The system will try to determine if the “NAT Address” or the real IP-address should be used
within signalling. This is done to make it possible to place calls to endpoints on the LAN as well as
endpoints on the WAN.
On:
The system will signal the configured “NAT Address” in place of its own IP-address within Q.931
and H.245. The NAT Server Address will be shown in the startup-menu as: “My IP Address: 10.0.2.1”.
Off:
The system will signal the real IP Address.
Example:
H323
NAT Mode: Off
H323 NAT Address
Enter the external/global IP-address to the router with NAT support. Packets sent to the router will then be
routed to the system.
In the router, the following ports must be routed to the system’s IP-address:
* Port 1720
* Port 5555-5574
* Port 2326-2485
Value space: <S: 0, 64>
Format:
String with a maximum of 64 characters.
Example:
H323
NAT Address: “”
H323 Profile [1..1] Authentication Mode
Set the authenticatin mode for the H.323 profile.
Value space: <On/Off>
On:
If the H.323 Gatekeeper Authentication Mode is set to On and a H.323 Gatekeeper indicates that
it requires authentication, the system will try to authenticate itself to the gatekeeper. NOTE! Requires
the Authentication LoginName and Authentication Password to be defined on both the codec and the
Gatekeeper.
Off:
If the H.323 Gatekeeper Authentication Mode is set to Off the system will not try to authenticate
itself to a H.323 Gatekeeper, but will still try a normal registration.
Example:
H323
Profile 1 Authentication Mode: Off
