USB Connector
The Enclosure Series comes with a familiar USB
Connector to fulfill both communication and power
needs. The standard A-style connector can be
mated to any device with a USB-A header. Most
commonly used with a PC, this connection creates a
virtual com port that offers a simple power solution
with a familiar communication scheme.

LED Indicators
The Enclosure Series has 6 General Purpose
Outputs which control 3 bi-colour LEDs. Red,
green, and orange-yellow colours can be
created using these software controlled GPOs.
Odd numbered GPOs control red while even
numbers switch the green aspects of the LEDs,
as shown in the table to the right.

Keypad Input
The Enclosure Series includes a 7
key, matrix style, embedded keypad
and may be configured to allow key
presses to be automatically
transmitted or polled. The keypad
can also be configured for typematic
or auto-repeating key presses. The
keypad is scanned only when
pressed to reduce electrical noise
and decrease latency to ensure key
input is received quickly and
correctly every time.
