Spectronix 100529A Manual

Software Programming Guide Rev 2022-02-16

USB Driver:

In order for Windows to recognize the device the USB driver must first be installed, after which it
appears as an additional COM port on the computer.
1. Copy the file "cdc_NTXPV764.inf" from the supplied CD to the hard drive.
2. Plug the unit into a free USB port. When the hardware installation wizard asks for the driver
location, browse to the "cdc_NTXPVista.inf" file on the hard drive.
3. After the driver has been installed right click "my computer" and select "properties". In the
properties window select the "hardware" tab. Click on "device manager" and expand the
"Ports (COM & LPT)" item. Locate the "Spectronix, Inc." entry and note the assigned COM
number, (ie "COM4"). This is the COM port that the software will use to communicate with the
Quad Cell Viewer.
Note, on some operating systems such as Window 7, manual USB driver installation may be
necessary. If the hardware installation wizard fails, go to "My Computer" > "Properties" > "Hardware"
> "Device Manager", and find the "Spectronix" or "SERIAL DEMO" entry under "Other Devices" and
select "Update Driver". At this point you will be able to browse to the location of the driver.

Ethernet:

Some devices allow communication over an Ethernet port. The default IP address is 192.168.1.160,
port 2101. The commands below can be used over USB or Ethernet.

Commands:

The device uses ASCII data to communicate with a host computer; the tables below list the individual
commands, parameters, and responses from the unit.

Notes:

1. All communication is initiated by the host.
2. Text is not case sensitive.
3. A space should be inserted between the command and any parameters.
4. All commands should be terminated with <CR>, <LF>, or both.
5. Responses from the OSTS are framed using a binary 0x00 character (start) and terminated
with 0x0D0AFF (<CR><LF>0xFF). These framing bytes are not shown in the tables below.
6. Response parameters are variable width, may contain white spaces, and are separated by
commas.
7. For the descriptions below, values inside quotations ("") are literal ASCII values, text inside
brackets ([]) are variable ASCII values, and values inside <> are binary values.
