Module 3000-44 Option 1, (2x128) Module, also known as Option “M”, has two
additional inputs on DB
This User Guide provides a basic description of the 3000-44 2 x 128 Coaxial Switch Matrix module. Also
included are installation and input connection procedures, programming information, service and
maintenance information.
3.2 General Description
This module is a dual wire 2 x 128 matrix switch. Each relay in the module is individually controlled. Any
and all relays can be closed. The module is designed to support precision testing designs such as ATE.
This module is ideal for high quality multi-channel measurement or stimulus switching. Each relay is
coaxially shielded to a separate analog ground plane. The Interface and mechanical construction meets
the specification of the VXIbus System Specification, rev 1.2 through 1.4. This module also has a factory
option for two independent 64 x 2 matricies.

Chapter 5 Controls and Indicators
The following controls and indicators are provided to select and display the functions of the ASCOR
3000-44 Module’s operating environment.
5.1 VXI Logical Address
The Logical Address Switch is dual circular switches, D1 and D2 which are located at the rear of the
module. The address can be set to any value between 1 and 255 (decimal) or 1 and FF (hexadecimal),
(address 0 is reserved for the resource manager). However, the Module fully supports Dynamic
Configuration as defined in Section F of the VXI specification, address 255 (FF) should be selected only if
the Resource Manager also supports Dynamic Configuration.
5.2 LEDs
The following LEDs are visible at the Module’s front panel to indicate the
status of the module’s operation:
5.2.1 “BUS” LED
This green color LED is normally off and will flash on when the module is addressed by the system.
5.2.2 “PWR” LED
This red color LED is normally on when the Module is Powered up.

Chapter 6 Internal Settings
The following items are inside the module and can be reached by removing the side cover.
6.1 Fuse
The ASCOR VXI 3000-44 uses a 10 Amp fuse in the +5 Volt line and is located on
the Mother Board (MB) assembly.
6.2 VXI
The VXIbus interrupt level is set with three bits in the “3Eh” register.
See the section on “A16 ADDRESS SPACE REGISTER DESCRIPTION”.
The interrupt level is factory set to “no interrupt”.
This module is a universal input/output multi-wire matrix switch. It contains eight 2x16 dual wire
matrices connected together through isolation relays. Isolation circuits are provided to maintain signal
performance by disconnecting unused sections of the matrices.
9.2 Programming
The Model 3000-44 a VXI register based module. The switch paths are controlled via VXIMAX™ which is
the 16/32 bit data controller. The Model 3000-44 can be programmed in 16 bit or 32 bit wide data.
Through your VXI controller, write the data to the appropriate register as shown on the register map for
the relay or relays in the register that is being closed. When the data bit is true, the relay chosen will be
closed. The state of the relays in a register can be determined by reading the desired register. The data
read back represents the value at the coil of the relay. This allows verification that the program register
has correctly controlled the relay coil.
The following register maps are shown in two configurations: 16 bit mode and 32 bit mode. In each
section,16 bit and 32 bit, the register map is organized to show the relay designation in each register. It
is followed by the register’s functionality and the path connections to the front panel.
Programming of the Model 3000-44 is very simple. The module is organized into 4 pins per register in16
bit mode or 8 pins per register in 32 bit mode. A pin is controlled by a group of 4 bits within the
program registers. These bits select one or more the the two available channels. Typically, only one
channel is assigned to a pin for optimum performance. Whenever a pin is selected in a group, the
appropriate channel isolation relay must be closed to complete the path. The isolation relays is the last
register in the mother board and daughter board.
For example:
To close pin 1 to channel A and to close pin 2 to channel B would set the following register:
Register 8000h: Control pins 1- 4
Register 8010h: Controls the isolation relays
