Power Supply Cable
The power cable has eight pins and goes into connector 4
in the upside view. This is the smallest
connector of the bottom board.
Be sure to connect a power supply between 7 and 9 Volts
(e.g. 7.2 V for rechargeable batteries with 6 cells).
CPU and servos to be connected may eitheruse the same or a
different power source.

Serial Download Cable
The serial download cable is used to set up RS-232 connections
between EyeBot and your PC, Mac or Unix Workstation, in order
to download software form the host system to EyeBot.
The serial download cable has 8 pins and goes into connector 2
in the upside view. If you look from the
up side it is the right one, if you look from the
top it is the left one. Do not confuse
the serial download connector with the background debugger
connector next to it.
The colored cable is connected to Pin 1, while Pin 10 on the EyeBot side is not used.

Line Out Speaker Cable
An active speaker may be connected to this line-out port (2 pins).
Like the camera cable it has to be inserted into the
bottom board. Do not connect speakers or
headphones directly, for this may destroy the circuit!
Servo Connector Cable
You may provide your own servo connector cable, in order to control
up to 12 servos (motors controlled by PWM, like in model airplanes)
directly from the microcontroller's TPU (timing processor unit).
For details on the servo connector, refer to the
hardware description of board IO1.
Background Debugger Cable
The Motorola 68332 allows debugging from a PC under DOS or linux
via the background debugger.
This is not a simple cable, but an electronic circuit,
which connects to connector 1 in the
in the upside view.
You will only need this cable+circuit, if you want to change
the EyeBot's on-board flash-ROM, containing the
RoBIOS operating system.
For details on software see the
background debugger,
for details on hardware see the
hardware description of board Core.
Servo port connector is used to interface the robot's servos (PWM motors).
