Simple Setup

The GPIO xNode has a simple setup page which provides access to the node ID (a node ID was likely already

assigned from the front panel at install) and conguration of the 6 GPIO ports. Included also in the page is a Java

script which provides status on each of the inputs and outputs.

Figure 7-8

Each port is represent by a row. The name column is used to assist with documenting the function of the port (or

the device which is connected to the port). The Channel column is used to congured the port. The input and output

columns show a grouping of boxes that represent each of the 5 GPIs and 5 GPOs. A high state (not active) is repre-

sented by a black box. A low state (active) is represented by a green state.

Conguration of a port can be accomplished in three different ways.

1. Port routing – The GPI activity on a port will trigger the GPO of the port you are conguring. (you are

routing the GPIs of a port to another port’s GPOs). This is done by entering in the IP address of the device

with a GPIO port followed by a forward slash and the port number. 10.216.0.121/5 – equates to port 5 at

address 10.216.0.121 new line 127.0.0.1/1 assigned to port 1 would be a loopback; GPI activity on the port

would trigger the GPO of the same port (used for testing)

2. Channel assignment – The GPIO port will follow the logic as dened by a control surface. Axia control

surfaces have predened logic for a source loaded to a fader. The logic is shared on the network through the

use of the unique channel number for a source. Refer to appendix A for common predened functions. To

assign a port to a channel, either manually type in the channel number in the eld OR use the browse button

to search the network for advertised sources.

3. Pathnder control – The Pathnder series of products has the ability to observe GPIO activity as well as

trigger GPO activity. Nothing is required to congure in the GPIO xNode, all the conguration is done in

Pathnder. Please refer to Pathnder documentation for detailed information.
