USB-ADP Serial Adapters

USB-ADP serial adapters allow you to connect your USB2000 Spectrometer,
HR2000 Spectrometer, USB-BP Battery Pack, or USB-LS-450 Light Source to
external equipment (such as handheld PCs, Light Sources, and computers) via
a custom connection block. The USB-ADP serial adapters connect to the
accessory connector on the spectrometer, light source, or USB-BP and provide
the various interfaces required by different types of hardware in your sampling
system. Each type of USB-ADP adapter has a built-in 5V power input, enabling
you to power the USB spectrometer without using the USB port on the PC.

There are three types of USB-ADP adapters currently available from Ocean
Optics:

• USB-ADP-PC

• USB-ADP-H

• USB-ADP-PX2

The following sections detail each serial adapter and provide information on compatible equipment, connection
tips, and required connection accessories.

The USB-ADP-PC features a 9-pin female serial connector that connects the spectrometer to the serial port of a
PC via a standard DB9 cable.

Items in Shipment

The USB-ADP-PC shipment includes the USB-ADP-PC adapter block, a male­to-female DB9 serial cable, a USB-CBL-PS 5V power supply, and a fastening
screw.

Note: The USB-ADP-PC-E (European version) of the USB-ADP-PC does not

include a power supply due to differences in household voltage.

Installation

Follow the steps below to install the USB-ADP-PC:

1. Plug the 10-pin interface on the backside of the USB-ADP-PC into the
10-pin accessory connector on the USB2000. If using an HR2000
Spectrometer, plug the 10-pin interface on the backside of the USB-ADP-PC into the right half of the 20­pin accessory connector on the HR2000.

Note: If you are using other equipment (such as the USB-BP or the USB-LS-450, connect those items

to the spectrometer in a “daisy chain” style before connecting the USB-ADP-H.

2. Secure the USB-ADP-PC in place on the spectrometer with the fastening screw.
