Misc. I/O Connector
The
Misc.
(Miscellaneous)
I/O
connector is a
multipurpose connector. It contains both digital and
analog signals used to connect external devices to
the Reference 600+.
All of its signals are isolated from both earth ground
and the Reference 600+
’s
Floating Ground. The
device connected to this connector establishes a
ground reference. This isolation allows the
Misc. I/O
connector to be connected to earth-grounded
apparatus, without compromising the Reference
600+
’s ground isolation.
A full description of this connector can be found in
Appendix C of this manual. This appendix includes
details such as connector pin-out, output and input
voltage levels, and full signal descriptions.
The following list is a short description of the signals
in the
Misc. I/O
Connector and their uses:
•
Sync Out and Sync In signal allow two or more
Reference 600+ potentiostats to use one data-
acquisition clock.
•
Four digital outputs can be used to turn on
external devices under control of an Explain
experimental control script.
•
Some of Gamry applications assign three of the
digital outputs to control stirring, flow of de-
aeration gas, and formation of mercury drops on
a mercury-drop electrode.
•
Four digital inputs that can be read in an Explain
experimental control script.
•
A 12-
bit D/A converter used to set “continuously variable” settings, such as
electrode-rotation rate on a
rotating-disk electrode.
•
A 5 V isolated power supply that can provide up to 50 mA of current for external circuitry.
I Monitor BNC
The
I Monitor
BNC connector is the output of the Reference 600+
’s current measurement circuit
. With
the exception of the filtering described below, it is the raw signal. It is high bandwidth on the less-sensitive
Caution:
Floating operation of Reference 600+ can be compromised by improper
connections to the
Misc. I/O
Connector. We do not recommend use of standard 15-pin shielded cables
with this connector. Custom cables with the shield connected to pin 6 of the D-connector are preferred.
