Telos Zephyr Xstream - Manual (Page 163)

Section 8: LIVEWIRE TM – IP Audio 151
System Settings (GPIO)
This page of the Xstream configuration has the GPIO input mode setting.
Since Livewire has the capability of “embedded” GPIO, there is often no need for connections to
switches as a means of controlling various external functions. You can use Livewire or the
traditional parallel port to manage GPIO at your studio location.
GPO (output) control is available simultaneously at both rear panel parallel port and Livewire.
GPO is sent to both the back panel and Livewire, and is triggered by the events specified on the
System menu.
GPI (input) mode must be specified as either Livewire or rear panel since we can take inputs
from the rear panel OR Livewire, not both at the same time. GPI comes from either Livewire or
the back panel, and triggers the event specified on the front panel Sys menu (or System web‐
page). This can be either a dial setup or sent through ancillary data to the remote end.
GPIO implementation can be tricky. Please check our web site for new application notes on this
topic and other topics that may involve complex configurations.
