Controlling the AM-4
17
Simple Serial Control
For serial communications
with a PC or an Alcorn
McBride Show Controller, use
the supplied straight-thru (not
Null) serial cable supplied
with the AM-4.
UDP communications take
place on Port 2639.
The AM-4 Digital Audio Machine may be controlled using serial RS-232C
messages via the rear DB-9 Programming Connector, or with UDP (User Datagram
Protocol) messages via the optional Ethernet interface. The serial data format is
9600,N,8,1: 9600 baud, 8 bits/byte, no parity, with one stop bit.
For UDP operation you must first set the IP address, Subnet Mask, and Gateway
address (if applicable) by issuing the corresponding serial commands. Please refer
to the Advanced Serial Protocol section in this manual for specific details on what
commands are used to set up the Ethernet interface.
AMI Terminal is a Windows application that can be used to control the AM-4 (as
well as other Alcorn McBride equipment). It is available on the Alcorn McBride
Website at
http://www.alcorn.com/support/software.html/amiterm.zip
.
The control protocol is ASCII-based, and many commands are identical to Pioneer
Laser Disc protocol. Upper or lower case characters can be used interchangeably.
The most commonly used serial commands for playback are:
Command
Function
Select File
Select a file
Play
Play the selected file
Loop Play

Pause

Command resumes playback.
Stop

The details of these commands are listed in this section. Many other commands are
also possible, and are summarized in the section entitled Advanced Serial Protocol.
Unless otherwise noted, all of these commands operate on any type of file, whether
audio track or Play List. Throughout this manual <CR> means carriage return, a byte
with the hexadecimal value 0D.
