MTS400 Series MPEG Test System Programmer Manual 1−1
Getting Started
This manual contains information on the Standard Commands for Programmable
Instruments (SCPI) and IEEE 488.2 Common Commands you can use to
program your MTS400 Series Player application. This manual also describes the
optional commands that control the optional interface cards.
Connecting to a Network
The MTS400 Series System has a 100/10 BASE-T port on the rear panel that
allows you to upload and download stream files.
This section provides instructions for connecting the MTS400 Series System to a
single PC or a network and setting the network parameters for the
100/10 BASE-T port.
The MTS400 Series System uses the rear-panel 100/10 BASE-T port to
communicate with a PC. Use one of the following two methods to connect the
instrument to your PC(s).
HIf you are connecting the instrument directly to a single PC, use a crossover
Ethernet cable to connect between the 100/10 BASE-T port on the MTS400
Series System and the Ethernet port on the PC. If you need to construct your
own crossover cable, Figure 1−1 shows the pin connections to change on a
straight cable to produce a crossover cable.
HIf you are connecting the instrument to your local Ethernet network, use a
straight Ethernet cable to connect between the 100/10 BASE-T port on the
MTS400 Series System and the Ethernet hub port of your local network. By
connecting to an Ethernet network, you can access the instrument using any
PC on the network.

The settings in the dialog box depend on whether a DHCP (Dynamic Host
Configuration Protocol) server is in the network connected to the MTS400.
When the DHCP Server is in the Network.
9. In the dialog box, select the Obtain an IP address automatically and
Obtain DNS server address automatically check boxes.
10. Click the OK button.
The MTS400 accesses the DHCP server and obtains the addresses automatically
when connected to the network.
Refer to the user documentation supplied with your server OS for detailed
information about DHCP server functions.
NOTE. Under some network environments, the MTS400 may not be able to obtain
the IP address automatically from a DHCP server. In this case, you need to enter
the appropriate address value in each submenu item.

Getting Started

When the DHCP Server is not in the Network. When the DHCP server is not in the
network, perform the following procedure to set the network parameters.
1. If you connect the MTS400 directory to a single PC:
a. In the dialog box, select the Use the following IP address check box.
b. Set the IP address parameter to be the same IP address as the PC’s
address except for the last number. The last number must be different
than the last number in the PC’s IP address.
c. Set the Subnet mask parameter to be the same net mask (subnet mask)
used by the PC. Do not enter a number if the PC does not have a net
mask.
d. You do not need to enter a Default gateway if you are directly connected
to a single PC.
2. If you connect the MTS400 to your local Ethernet network:
a. In the dialog box, select the Use the following IP address check box.
b. Ask your local network administrator and set the appropriate addresses.
CAUTION. To prevent communication conflicts on your Ethernet network, ask
your local network administrator for the correct numbers to enter in the dialog
box if you connect the MTS400 to your local Ethernet network.
3. Verify the Ethernet connection by using a ping command from the PC.
Network Interface Specifications
The MTS400 Series System supports remote control using the Ethernet interface.
This section describes the network interface specifications for the instrument.
The TCP/IP is used as the network protocol. The commands can be sent from the
application program through the socket interface of the TCP/IP. Also, the query
can be received through the interface.
Keep the following in mind while controlling the instrument remotely with the
Ethernet interface.
HThe LF (linefeed) or CR (carriage return) code is needed at the end of a
message as a terminator. Use the Communication dialog box or the
:SYSTem:COMMunicate:SOCKet:RXTERM command to set which
terminator is used.

HThe IEEE 488.1 standard (for instance Device Clear, Service Request, etc.) is
not supported.
HThe Message Exchange Control Protocol in the IEEE 488.2 is not supported.
However, the common commands such as *ESE and the event handling
features are supported.
HThe Indefinite format (the block start at #0) in the <ARBITRARY BLOCK
PROGRAM DATA> of the IEEE 488.2 is not supported.
Checking Remote Command Operation
To check remote command operation of the MTS400 Series System, perform the
following procedure:
1. Connect the instrument to your PC using an Ethernet cable (refer to
Connecting to a Network on page 1−1).
2. Click Windows Start button and select Run from the start menu.
3. In the dialog box, type telnet and then click OK.

The Connect dialog box appears.
7. In the Host Name field, enter the IP address of the MTS400 Series System.
8. In the Port field, enter the port number set by the Communication dialog
box or the :SYSTem:COMMunicate:SOCKet:PORT command (the default
value is 49152).
9. Click Connection.
10. Type *IDN? in the command line and press the Enter key.
11. Check that the ID information of the MTS400 Series System appears on the
PC.

Syntax and Commands
This section contains information on the Standard Commands for Programmable
Instruments (SCPI) and IEEE 488.2 Common Commands you can use to
program your MTS400 Series Player application. The information is organized
in the following subsections: Syntax, Functional Command Groups, and Remote
Commands.
SCPI Commands and Queries
SCPI is a standard created by a consortium that provides guidelines for remote
programming of instruments. These guidelines provide a consistent program-
ming environment for instrument control and data transfer. This environment
uses defined programming messages, instrument responses, and data format
across all SCPI instruments, regardless of manufacturer. The MTS400 Series
Player application uses a command language based on the SCPI standard.
The SCPI language is based on a hierarchical or tree structure (see Figure 2−1)
that represents a subsystem. The top level of the tree is the root node; it is
followed by one or more lower-level nodes.
SIZE
RECord
TARGet
TIMETYPE
Root node
Lower-level
nodes
Figure 2−1: Example of SCPI subsystem hierarchy tree
You can create commands and queries from these subsystem hierarchy trees.
Commands specify actions for the instrument to perform. Queries return
measurement data and information about parameter settings.
SCPI commands are created by stringing together the nodes of a subsystem
hierarchy and separating each node by a colon.
In Figure 2−1, RECord is the root node and TARGet, TYPE, SIZE, and TIME
are lower-level nodes. To create a SCPI command, start with the root node
RECord and move down the tree structure adding nodes until you reach the end
of a branch. Most commands and some queries have parameters; you must
Creating Commands

Syntax and Commands
2−2 MTS400 Series MPEG Test System Programmer Manual
include a value for these parameters. If you specify a parameter value that is out
of range, the parameter will be set to a default value.
For example, RECord:TARGet:TYPE DISK is a valid SCPI command created
from the hierarchy tree in Figure 2−1.
To create a query, start at the root node of a tree structure, move down to the end
of a branch, and add a question mark. RECord:TARGet:TYPE? is an example of
a valid SCPI query using the hierarchy tree in Figure 2−1.
Every parameter in the command and query descriptions is of a specified type.
The parameters are enclosed in brackets, such as <pattern>. The parameter type
is listed after the parameter and is enclosed in parentheses, for example,
(discrete). Some parameter types are defined specifically for the MTS400 Series
Player application command set and some are defined by
ANSI IEEE 488.2-1987 (see Table 2−1).
