GPIs testing.
NETBOX 4 MH features 4 optically-coupled GPIs on the "GPIO - IN 1-4 / OUT 1-4" DB15
connector and another 7 GPIs (also optically-coupled) at the "SCR-03 - GPI" RJ45 connector.
When a GPI is activated in the unit (the circuit between the corresponding pin and the ground
pin gets closed), the corresponding button in “GPI’s” section will light in red. This GPI will be
also transmitted as a Virtual GPO through the network to all the IP addresses configured in
“Remote IP” submenu (see section 3.2.2.3 of this manual). In order to activate a GPI with
internal voltage, you have to connect the floating ground to the connector chassis.
All 7 GPI in the "SCR-03 - GPI" connector can be activated from the corresponding push-
buttons in the STUDIOBOX or SCR-03 control box. Those labeled as USER KEYS 1 to 5 are
latching, while the ones labeled as MUTE and TECH T. BACK (or CUT and CUE in the case of
SCR-03) operate only when they are pressed down.
"Virtual GPI/O in AEQ systems" application note, available at
www.aeq.es
, explains how to
configure these GPI in order to produce the remote cut and pre-listen control actions on
different control consoles from a radio booth.

3.2.2.3. "Remote IP" submenu.
"Remote IP" submenu, accessed from the drop-down menu “Administration” by clicking on the
corresponding icon, allows you to manage the virtual GPIs and GPOs.
The connection port (2001) is a fixed parameter and it's shown for informative purposes only.
"Virtual GPI to Physical GPO association":
Allows for the control of the status of every GPO in NETBOX 4 MH as a response to remote
commands sent from another Netbox or AEQ IP devices such as Forum, Capitol, Phoenix
audiocodecs, Systel IP and Audio+. The parameters of a virtual GPI are the IP address of the
unit we want to receive the Virtual GPI from, and the “Id”, an identifier from 0 to 255 that must
match with the “Id” number configured in the device that transmits the corresponding virtual
GPO.
