GPIB Bus (option)
IEEE488 (GPIB) is an international bus interface standard used on intelligent instruments. IEEE is the English
abbreviation of Institute of Electrical and Electronics Engineers, and 488 is the standard number. Through this
interface, ST2523 can communicate with PC or others intelligent equipments and meanwhile can make up
automatic test system with the other test equipments. Up to 15 equipments can be connected on a same bus.
ST2523 applies IEEE488.2 and the interface plate can be inserted in any one of the three expansion slots
Control command system is open so that user can use the PC operation interface provided by ST2523 or take
measurements by the control command system. The control command system supports most functions of the
instrument, that is to say, user can execute almost all operations on PC. Thus remote control to the instrument is
realized.
When configuring a GPIB system, the following restrictions must be adhered to.
1
．
The total length of cable in one bus system must be less than or equal to two meters times the number of
devices connected on the bus (the GPIB controller counts as one device) and the total length of cable
must not exceed 20 meters.
2
．
A maximum of 15 devices can be connected on one bus system.
3
．
There are no restrictions on how the cables are connected together. However, it is recommended that
no more than four piggyback connectors be stacked together on any one device.
