ESP-00 II Indicators and Features (cont.)
Front Panel LED Indicators
POWER - Power on or fault-state indication
• Green: Power on, normal operation
• Red: Fatal Error.
STATUS - Operating condition of the unit.
• Green: Config loaded, operating normally
• Yellow: DSP resource shortage
• Red: Config error • Off: No config loaded
ETHERNET - Connection status indication
of the Ethernet control network
• Green: Link established
• Yellow: Tx activity
• Red: Rx activity
SERIAL - RS-232 or CC-16 serial command
status indication. (Does not indicate Serial
over Ethernet activity)
• Green: CC-16 command transmitted
• Yellow: CC-16 command received
• Red: RS-232 Rx/Tx activity
Rear Panel Controls and Connections
Mic/Line Inputs
One 4x4 Mic/Line card will be required to
perform the test procedures in this service
manual.
Each 4x4 Mic/Line card occupies two slots.
The input connectors (green) and the input
LEDs appear in the first slot. The output
connectors (orange) and LEDs appear in the
second slot. A microphone or line level audio
source can be connected to the Mic/Line
inputs using one of the following cable types.
Refer to the diagram below.

General Purpose Inputs/Outputs
The ESP-00 II includes one GPIO card in
slot 1 providing eight control inputs and eight
control outputs. A second card can be added
to GPIO slot 2.
Inputs
Switches and potentiometers can be con-
nected to the control inputs to control var-
ious functions in the system. For example,
simple ON/OFF switches can be connected
and then programmed to invoke presets,
select scenes, or invoke a snapshot of a
control. Likewise, 10k linear potentiometers
can be connected to control gains in the
system.
Inputs contain a 5k ohm pull-up resistor
allowing SPST switches to be wired from
input to ground. Potentiometers can be wired
in series from the control input to ground.
Outputs
LEDs and relays can be connected to
general purpose outputs to indicate state

changes in the system (e.g. preset or scene
