Chapter 5 -- Panel Indicators and Connectors--Rear Panel
5 - 4
By default, the label in this area shows the instrument's Serial Number written in white text on a blue
background. Interface 1000 users can chose a different label. A sheet of alternate labels is provided with each
instrument and a user editable Excel file can be found on the Gamry website.
Full instructions describing the process of changing a label can be found near the end of the Installation chapter
(Chapter 3).
Rear Panel
The rear panel contains several connectors. Figure 3 - 2 shows a picture of the Interface 1000 rear panel.
Power In Jack
The Power In jack is a 4-pin Power DIN connector. The Interface 1000 derives all its power from +48 volts DC
input through the Power In jack. The input current is less than 1.5 amps.
We recommend that you always use the external power supply supplied with your Interface 1000 to supply DC
power to the instrument. This supply is rated for operation from 100 to 240 volts AC, at frequencies from 47 to
63 Hz. It should therefore be useable worldwide. While an Interface 1000 may work with other power
sources, we cannot guarantee it will work to its full specifications.
If you have to use the Interface 1000 with a different supply, make sure that the supply is regulated, has an
output between 46 and 50 volts, and supplies 1.5 amps of load current.
Caution
Power input voltages less than 40 volts or greater than 52 volts can damage the Interface
1000’s power supply.
Chassis Ground
The rear panel Chassis Ground banana jack is intended for one use only. When the Interface 1000 is used with
cells isolated from earth ground, connecting the chassis ground to earth ground may lower the noise measured
in the system. Note that the chassis of the Interface 1000 is connected to Floating Ground. Safety information
concerning this is in Chapter 1.
A banana plug is the only way you can connect to the Chassis Ground jack. A wire is then used to connect the
banana plug to earth ground.
A black banana-plug to banana-plug lead has been provided with your Interface 1000. You may find it useful
when making this earth ground connection.
USB Port
The USB port on the rear panel of the Interface 1000 is a Type B connector as defined in Revision 1.1 and 2.0
of the USB Specification. You use a standard, shielded, Type A/B cable to connect this port to a computer’s
USB port or a USB hub (preferably an externally powered hub). The two ends of a Type A/B cable are
different. The more-rectangular end plugs into the computer and the more-square end plugs into the Interface
1000.
A suitable USB cable was included with your Interface 1000 shipment. If this cable is lost, you can replace it
with a cable from your local computer retailer.
The Interface 1000 is a High Speed USB 2.0 peripheral, capable of data transfer at 480 Mbits/second. If it is
plugged into a computer port incapable of High Speed operation it will downgrade to USB 1.1 full speed
operation (12 Mbits/second) causing slower data transfer.
The Interface 1000 USB port is compatible with Revision 1.1 and 2.0 of the USB specification. It supports the
Windows Plug-n-Play mechanism, including dynamic connect/reconnect.
The front panel USB LED should be green whenever a valid computer to Interface 1000 connection has been
made and both the computer and Interface 1000 are fully powered.
