GPIO configuration
xConfiguration 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 (+12 V). When activated as output, they are set to 0 V. To
activate them as input, they must be pulled down to 0 V.
Requires user role: ADMIN
Value space: <InputNoAction/OutputManualState/OutputInCall/OutputMicrophonesMuted/
OutputPresentationOn/OutputAllCallsEncrypted/OutputStandbyActive/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 +12 V or 0 V, 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 presen-
tation is not active.
OutputAllCallsEncrypted: The pin is activated when all calls are encrypted, deactivated when one
or more calls are not encrypted.
OutputStandbyActive: The pin is activated when the system is in standby mode, deactivated when
no longer in standby.
InputMuteMicrophones: When the pin is activated (0 V), the microphones will be muted. When
deactivated (+12 V), the microphones are unmuted.
Example:
xConfiguration GPIO Pin 1 Mode: InputNoAction
H323 configuration
xConfiguration H323 NAT Mode
The 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.
Requires user role: ADMIN
Value space: <Auto/Off/On>
Auto: The system will determine if the H323 NAT Address or the real IP address should be used
in signaling. This makes it possible to place calls to endpoints on the LAN as well as endpoints on
the WAN. If the H323 NAT Address is wrong or not set, the real IP address will be used.
Off: The system will signal the real IP address.
On: The system will signal the configured H323 NAT Address instead of its real IP address in
Q.931 and H.245. The NAT Server Address will be shown in the startup-menu as: "My IP Address:
10.0.2.1". If the H323 NAT Address is wrong or not set, H.323 calls cannot be set up.
Example:
xConfiguration H323 NAT Mode: Off
xConfiguration 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. Note that NAT cannot be used when registered to a gatekeeper.
In the router, the following ports must be routed to the system's IP address:
* Port 1720
* Port 5555-6555
* Port 2326-2487
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: A valid IPv4 address or IPv6 address.
Example:
xConfiguration H323 NAT Address: ""
