5 Remote Control via LAN with SCPI Command
Syntax
5.1 Introduction
The EM510 can be remote controlled via LAN by means of SCPI command syntax. The control
commands and the status reporting system are described in this chapter. The socket RJ45 is on the
back side of the EM510.
Within the TCP/IP protocols, the EM510 supports the SCPI command syntax version 1993.0 (Standard
Commands for Programmable Devices). The SCPI standard is based on IEEE 488.2 and is aimed at
standardizing device-specific commands, error handling and status registers (see "Notation" on page
5.13).
This section assumes a basic knowledge of programming and controller operation.
The requirements of the SCPI standard for command syntax, error handling and configuration of the
status registers are explained in the relevant sections. Tables and figures provide a fast overview of the
commands implemented in the device and the bit assignment in the status registers. The tables are
supplemented by a comprehensive description of every command and the status registers. Detailed
programming examples of the main functions are to be found in Annex E: LAN Programming Examples.
5.1.1 Remote Control via LAN interface
The default values of the interface parameters of the EM510 are configured
with the host name or IP-address 89.10.11.23 and port number 5555.
For more information see the Interfaces Description in the annex.
1. Connect the unit with controller via Ethernet cable by RJ45 plugs. In case of a direct connection to a
computer network card a crossed cable must be used. If the EM510 is connected via hub or directly
to a network, a 1-to-1 cable is required.
2. TCP/IP must be installed on the controller. The network card can be set to half duplex or full duplex.
The EM510 determines the respective configuration during the switch-on and reacts
correspondingly.
3. If the EM510 is operated in a network, it must be set to a network-compatible IP address. Consult
your network administrator for further information. See also Annex D: LAN Configuration.
4. The ping command is a simple way to check whether the controller is able to connect to the EM510.
Just enter the command “ping <IP address>“ (e.g..: “ping 89.10.11.23“) “ in the DOS box.
5. Commands can be sent to and messages received from the EM510 by means of a Telnet
application which is started and configured with the interface parameters of the EM510.
6. To test the connection, enter *idn?, for example, to query the EM510's identification. The response
string should then be displayed.
Note:
If the same IP address already exists for a different device, the corresponding entry must be erased
from the ARP table before setting up a new connection. This can be done in the DOS box by entering
the command "ARP -d <IP address>".
