Setting up AMP remote control
You can use Advanced Media Protocol (AMP) to control a Profile XP system channel.
This protocol is an extension of the Odetics protocol and is supported through the
Profile XP AMP application. External control devices can be connected via rear panel
RS-422 serial connectors, or an Ethernet network connection.
The AMP application acquires a single channel (Play, Record, or Play-Record) at a time.
The AMP application interface runs in the following modes:
• Local control mode — The Profile XP channel can be controlled by either the local
AMP application or by third party applications such as a hardware controller or a
software application.
• Status mode — The Profile XP channel is controlled by a remote third party
application and the local AMP application only monitors activities on the channel.
When you are using a remote third party application, AMP protocol supports the use of
a two-head model in that two clips are loaded simultaneously, as follows:
• Active clip — The AMP “preset id” is considered the active clip that controls
channel resources.
• Preview clip — The AMP “preview preset id” is considered the preview clip.
Generally the preview clip begins playing after the active clip completes, at
which point the preview clip becomes the active clip.
Configuring AMP protocol control
To configure a Profile XP channel for control by the AMP protocol, do the following:
1. Make sure that the channel you intend to control by the AMP protocol is not
currently allocated to an application.
2. Open C:/profile/ampclient.exe. The AMP application opens.
