5. Descriptions of GPIB Interface
(Commands Same as RS232 Interface)
5.1 Overview
The meter 16502 can be controlled remotely and is able to perform data transfer function via
the IEEE-488.2/RS232 interface.
5.2 Specification of IEEE-488 Interface
1. For IEEE-488 interface, it is able to use the commands of 488.1 (compatible with
KEITHIEY 5802) and 488.2 interfaces (including common and general commands.) It
must be set in 16502 SYSTEM SETUP prior uses.
2. This chapter mainly explains the commands of GPIB interface bus to facilitate users in
writing programs to control the 16502 for handling the tested data.

5.2.2 Code Used for Data Transfer
The code used for data transfer is the ISO ASCII code.
5.2.3 TALK/LISTEN Function
"TALK/LISTEN" denotes full programmability and is suitable for the controller or computer
system with data processing.
