The Z/IP ONE and Livewire GPIO explained

Updated 1 month ago by Bryan Jones

Scope

This document covers Livewire GPIO in the Telos Z/IP ONE Broadcast IP Codec. Z/IP ONE also has physical GPIO via a parallel port on the back of the unit. Only Livewire GPIO is discussed in this article.


Description

The Telos Z/IP ONE Broadcast IP Codec (we'll just call it a Z/IP from here on) is a Livewire device. In addition to Livewire audio in and out, it also includes Livewire GPIO for interfacing with the Z/IP's built-in GPIO capabilities.

The Z/IP's GPIO is configured on the GPIO page of the Web UI shown here.

The functions of each of the eight "Bits" are controlled by the pull-down options and are explained in the Z/IP manual.


Axia GPIO

The Z/IP has two Axia GPIO ports that mirror the configuration set on the configuration page, with one exception. While the Z/IP has only EIGHT bits, each Livewire GPIO port has 5 pins (or 10 total). Only the first FOUR pins on each GPIO port get used. The 5th Pin is not used.

  • GPIO Port 1, Pin 1 - Z/IP Bit 1
  • GPIO Port 1, Pin 2 - Z/IP Bit 2
  • GPIO Port 1, Pin 3 - Z/IP Bit 3
  • GPIO Port 1, Pin 4 - Z/IP Bit 4
  • GPIO Port 1, Pin 5 - Not used
  • GPIO Port 2, Pin 1 - Z/IP Bit 5
  • GPIO Port 2, Pin 2 - Z/IP Bit 6
  • GPIO Port 2, Pin 3 - Z/IP Bit 7
  • GPIO Port 2, Pin 4 - Z/IP Bit 8
  • GPIO Port 2, Pin 5 - Not used
The "Not used" ports can not be assigned to other functions. They are not available to the Z/IP.

For those that understand the Livewire GPIO vernacular a bit better, the GPIO can be restated like this.

***** GPI are "receive from remote" or defined OUTPUT function *****
GPI 1 hhhhh
1234
^^^^^
||||\_ Unused
|||\__ Z/IP Bit 4
||\___ Z/IP Bit 3
|\____ Z/IP Bit 2
\_____ Z/IP Bit 1

GPI 2 hhhhh
5678
^^^^^
||||\_ Unused
|||\__ Z/IP Bit 8
||\___ Z/IP Bit 7
|\____ Z/IP Bit 6
\_____ Z/IP Bit 5

**** GPO are "send to remote" or defined INPUT function *****
GPO 1 hhhhh
1234
^^^^^
||||\_ Unused
|||\__ Z/IP Bit 4
||\___ Z/IP Bit 3
|\____ Z/IP Bit 2
\_____ Z/IP Bit 1

GPO 2 hhhhh

\_____ Z/IP Bit 5


Remember

The Outputs you configure in the Z/IP, shown here, will arrive as a Livewire GPI.

Inputs you configure in the Z/IP, shown here, will arrive as Livewire GPO.
