There are many ways to control your XAP 800 and other networked units.This

chapter explains how to set up control for Control/Status A port using GPIO Builder,

XAP IR Remote and ClearOne Control Panel using Remote Builder and RS-232 port.

Control/Status A

GPIO stands for general-purpose input/output. The GPIO Builder is used to establish

the pin assignments for the 16 user definable pins on Control/Status Port A. These

pins provide control via contact closure and status via open collector functions in the

unit. Note that the pins numbered in blue are command pins; the pins numbered in

green are status pins. The default pin assignments are listed on page 88. You can

open GPIO Builder from the Flow Screen or the G-Ware toolbar.

To program control/status pins

Select the

Control/Status A

pin you want to configure.

The current (default) pin assignment is displayed in the Active

(Low)/Inactive (High) Command box.

Select the

Device Type

and

from their respective lists.

Select the

Command

from the Command list. When you select a command,

a description of it appears in the Command Description box.

Select the command parameters from the argument lists. The parameters

that are available depend on the command selected. When you select an

argument, a description of it appears in the Argument Description box.

Click

Apply

to apply the changes you have made to the selected pin. Or, click

Clear

to clear any programming for the pin.

CHAPTER 6: Control

GPIO Builder

If you want to create pin

assignments specific to a

preset, you will need to

open the GPIO Builder from the

Preset Configuration pane (see

page 57) and select Use in Preset.

✍ ✍

Figure 6.1. GPIO Builder Window

GPIO commands can be

configured only for the

local XAP 800 unit.
