2 Remote System

2.1 Basic Information

Using a GPIB or LAN connection, the CO3000 can be triggered and used to control devices

connected to it. The commands used for this are coded in simple, readable character strings. The

following applies to all connections:

 Character set: ASCII 8Bit

 All incoming and outgoing communications are completed with LineFeed “LF” (0x0A)

◦ for IEEE488, LF and/or EOI can be used

 Maximum length of incoming character string: 64 bytes, including LF

 Maximum length of outgoing character string: 64 bytes, including LF

 All characters must be transmitted in capital letters. The separator is a space (0x20)

 All commands sent to the CO3000 are confirmed with a return value for each

◦ Each command can however also be answered with an error message.

2.2 Connecting via GPIB

2.2.1 Connection

To connect remotely via GPIB, the PC must have a GPIB interface. There are several suppliers for

suitable add-on cards or USB adaptors, e.g. National and Agilent. You will need an IEEE-488 cable to

connect it with.

The CO3000 is delivered with the default GPIB address 7. This can be changed in the controller’s

settings.

2.2.2 Communication

Communication runs on the GPIB standard. To receive commands, the CO3000 must be addressed

as a listener and to send the return value it must be addressed as a talker. Return values can be read

several times.

Return values are available for reading immediately after being received and decoded.
