Appendix B-2230 Operators
APPENDIX B
This appendix supplies some additional information about connecting and using the RS-232-C Communications Option.
Printer/Plotter switch settings for some tested formats and plotter types are shown for both RS-232 and GPIB (Option 10).
Some common questions and answers about the Communications Options are included. Most of the questions are about
Option 12.
RS-232-C DEVICE INTERCONNECTION
INTRODUCTION
This information will aid you in determining the cabling
needed to hook your 2200 Family oscilloscope to other
RS-232-C devices. The majority of interconnection situa-
tions that you may see are covered.
The RS-232-C standard defines the interconnection
between two types of devices. They are Data Terminal
Equipment (DTE} and Data Communications Equipment
(DCE). A DTE device that conforms to the standard has a
male RC-232-C connector. Examples are terminals, com-
puters, and printers. Generally, the DTE device is the
source of the data, but this is not always the case. A DCE
device that conforms to the standard has a female
RS-232-C connector. An example of a DCE device is
a modem.
DETERMINING DEVICE TYPE
When interconnecting your 2200 Family oscilloscope to
other RS-232-C devices you must determine the device
type and the connector type. From that information, the
interconnection cable you need can be determined.
NOTE
You cannot reliably determine if a device is DTE or
DCE by simply looking at the RS-232-C connector.
You must verify the device type from its operator or
service manual.
1. To which "logical" type of device are you connecting?
From the equipment manual, find out if the device is
DTE or DCE.
2. Which "physical" type of connector does the device
have?
Male is standard for a DTE connector.
Female is standard for a DCE connector.
If you have a DTE device with a male connector or a
DCE device with a female connector, you may use a stan-
dard RS-232-C "straight through" interconnection cable. If
the connections are not standard, read the Interconnection
Rules. Then read the Interconnection Cable-Type
Identification information to find the interconnection cable
type you will need for your application.
