3Introduction to the Plug-In Modules for the 34980A

Slot and Channel Addressing Scheme

The eight module slots in the 34980A are arranged as shown below.

Slot number designations

The slot and channel addressing scheme for the 34980A follows the form sccc where s is the mainframe slot number (1 through 8) and ccc is the three- digit channel number. Note that MUX channels numbers are derived differently from matrix modules, and channel numbers for matrix modules are derived differently between 1- wire and 2- wire configuration modes.

Displayed Number... Means This... Determined by...

1014	A MUX module is in slot 1, channel
	of interest is 14. This channel is
	labeled on the simplified
	schematics as 014 on Bank 1 of
	each MUX module.
3921	A MUX or matrix module is in slot
	3, channel of interest is 921
	(Analog Bus relay on ABus1)
5304	A 34931A, 34932A, 34933A (2-wire
	mode) matrix module is in slot 5,
	crosspoint is row 3, column 4.
2437	A 34933A matrix module in 1-wire
	mode is in slot 2, matrix of interest
	is 4, crosspoint is row 3, column 7.

MUX module channel numbers are determined by the numbers assigned to the switches on each bank. Channel numbers contain three digits.

MUX and matrix channel numbers for the Analog Bus relays are determined by the number assigned to the relays.

Matrix module (in 2-wire mode) channel numbers are derived from the crosspoint or intersection of rows and columns, columns having two digits).

34933A matrix module (in 1-wire mode) channel numbers are derived from a specific matrix number and the crosspoint or intersection of rows and columns on that matrix.
