Introduction
1
This manual details the methods to operate the SS7012 DC Signal Source using
communication functions, as well as all the commands used by the SS7012.
When the communication function is used, the SS7012 can be manually oper-
ated using communication terminal software. Furthermore, application software
to automatically control the SS7012 can be run.
The following symbols in this manual indicate the relative importance of cautions
and warnings.
Introduction
Safety Information
Indicates that incorrect operation presents a possibility of injury to the
user or damage to the instrument.
Indicates advisory items related to performance or correct operation
of the instrument.

SS7012 Remote Interface Overview
2
Figure 1 shows a block diagram of the SS7012 remote interface.
Operating
principle Communication between a personal computer and the SS7012 is virtual RS-232
serial communication. While the USB interface is installed as the transmission
route, actual communication uses RS-232.
It is necessary to issue RS-232 commands via the virtual COM port.
When RS-232 commands are issued to the virtual COM port, commands are
sent to the SS7012 in the following order. (For the receipt of data, the order is
reversed.)

Sending a command Receiving data

Connect a USB cable
3
Before connecting the USB cable, install the USB driver on the personal com-
puter. The USB driver is located on the CD that accompanied the SS9000 Com-
munication Package.
For installation instructions, please refer to the instruction manual of the SS9000
Communication Package.
After installing the USB driver, connect the personal computer and SS7012 as
shown in Figure 2. The virtual RS-232 COM port will be automatically assigned
to the USB port.
In order to send communications, the serial interface parameters of the SS7012
and personal computer must match.
Table 1 shows the settings required for communication. These parameters are
fixed. If any other settings are used, communication is not possible.
While the SS7012 is communicating, key operation of the SS7012 cannot be
used. (On the LCD of the SS7012, is on.)
To enable key operation of the SS7012, push the LOCAL key of the SS7012.

Overview of Command Type and Format
All commands can be entered in upper and lowercase.
Command Format and Query Format
The commands control instrument functions.
The following example shows a command and its associated query:
Example 1:
(Transmission command)
(Response 1)
(Response 2)
CVV 1.0000<CR><LF> (Set the source voltage value to 1 V.)
OK<CR><LF> (When the transmission command was sent
normally)
CMD ERR<CR><LF> (When there is an error in the transmission com-
mand)
Example 2:
(Transmission command)
(Response 1)
(Response 2)
RMV?<CR><LF> (Query the voltage monitor value)
1.0000<CR><LF>
CMD ERR<CR><LF> (When there is an error in the transmission com-
mand)
Query Command
The query command ends with a question mark "?".
Terminator (delimiter)
A terminator is a character, which identifies the end of a command string. A valid
terminator consists of two-byte data:
<CR> (Carriage Return, ASC(&H0D))
<LF> (Line Feed, ASC(&H0A))

(Response 1) OK<CR><LF> (When the setting command was pro-
cessed normally)

Data Types Returned message is the ASCII string from the instrument responding to a
query.
A query is a command followed by a question mark.
The following table 2 is explanation for data types.
Response Messages

ASCII ASCII string XXXXXXXXXXXX (device ID etc.)
When key operation is used with the SS7012 and memory write mode or mem-
ory clear mode is enabled, commands are disabled and “CMD
ERR<CR><LF>” is returned. Before sending a command, always exit memory
write mode or memory clear mode.
