2.Press Dto scroll to "IEEE"; then press Eto enable the IEEE-488 interface and disable the RS-232 interface. "IEEE" will not appear in the left display if the IEEE- 488 interface is not installed.

3.The instrument must now be assigned an address ("0" to "30", inclusive). If you want to make a change, scroll to the desired address with the Gand Dbuttons. Then press Eto select the displayed address. The address remains selected until it is changed.

Note

Pressing Cat any point returns the instrument to the Inactive Mode, leaving the original interface selection unchanged. If RS-232 was active, the instrument returns to RS-232, with all parameters unchanged.

Installation Test

The procedure below demonstrates how the instrument processes a computer interface command and, at the same time, confirms that the instrument has been properly set up and cabled for IEEE-488 operations:

Note

This is a program as entered from a Fluke 1722A Instrument Controller using Fluke BASIC commands. Syntax may vary with the host computer and language.

Enter the following at the host:

INIT PORT 0 <CR>

CLEAR PORT 0 <CR>

PRINT @ <address of instrument>, "*IDN?" <CR>

INPUT LINE @ <address of instrument>, A$ <CR>

PRINT A$ <CR>

1.Verify that the instrument sends the following identification response: FLUKE,2620A,0,Mn.n An.n Dn.n

Mn.n identifies the main software version.

An.n identifies the A/D software version.

Dn.n identifies the display software version.

If the instrument does not respond to the test procedure as indicated, make the following checks:

1.Check all cable connections.

2.Check that the interface has been properly enabled and addressed.

How the Instrument Processes Input

The following paragraphs summarize how the instrument processes input that is received from a host (or stand-alone terminal).

Note

In this manual "input" means a string sent to the instrument from a host. "Output" means a string sent from the instrument to the host.
