Ethernet Interface (optional)
The AM-4 Digital Audio Machine can be ordered with an optional Ethernet Module
which adds control and file transfer capabilities to the AM-4 over a standard Ethernet
connection. The Ethernet interface is provided on a standard RJ-45 jack.
Two LED indicate Ethernet status as shown below. The Green LED should be on
whenever an active Ethernet connection is detected, and the Yellow LED flashes
whenever Ethernet activity occurs.
Please refer to the sections in this manual explaining FTP and UDP operation for
more details on Ethernet functionality.
Power
The power input is a 2.5x5.5x10mm barrel connector with center pin (+) and the
outer rim (-). The AM-4 Digital Audio Machine requires 12.0 VDC to 25.0 VDC at 2
Amp. This is useful for mobile applications where an automotive battery is used to
power a Compact Flash Card or Compact Flash Card hard drive. DO NOT EXCEED
THE SPECIFIED INPUT VOLTAGE RANGE. An external 100-250 VAC 50/60Hz
input universal switching power supply is provided with the unit.
A plastic strain relief can be threaded through slots near the power input jack to
secure the barrel connector if the AM-4 is installed in a high-vibration environment.
Serial Port: DB-9 Connector
A serial cable is
provided with each AM-
4 Digital Audio
Machine.
This input is a standard DB-9 male RS-232C connector, intended to be connected to
a PC using a straight-through (
not null-modem
) 9-pin cable. The pinout appears
below.
