BD CARV II Installation and User’s Guide
Touch Pad Controller Connections
Except for the BNC connection for the optional external shutter trigger, all input/
output is connected to the back of the touch pad controller.
There are three connections that need to be established:
•
The DB-9 connector on the far right is the RS-232 serial connector for
communications with a PC host. A standard, straight-through DB-9
extension cable is provided to establish this connection with a PC COM
port.
•
The next connector to the left is a DB-25 that provides all the power and
signals to the main unit. The interconnect cable between the touch pad
controller and the main unit is NOT a standard DB-25 extension cable.
Because both power and clock signals are transmitted through the cable, it
uses a larger wire gauge and more robust shielding. Replacing this cable
with a standard DB-25 cable may cause the instrument to malfunction.
•
The circular, five-pin DIN connector accepts the plug from the provided
power supply. This power supply provides the necessary 5 and 12 V DC for
the CARV II. To make sure the polarity and power capacity is correct, this
supply should only be replaced with one of the same type. The power
switch at the rear of the touch pad controller switches power for both the
touch pad and the main unit simultaneously.
