Functional Description
2.1 Introduction
This manual provides the necessary information for the operation and maintenance of the Model 3000-
524, quad 1x12 coaxial switch tree VXI Module.
2.2 General Description
This module contains four very high frequency 1x12 coaxial relay trees. The shields to the 12 inputs are
switched to allow isolation of the coaxial shield from the common shield plane of the switch tree. The
3000-524 is a register based VXI module. The register map is carefully laid out for easy software control.
The interface and mechanical construction meets the specification of the VXIbus System Specification,
rev. 1.2 and 1.3.

Operation Manual
Controls and Indicators
The following controls and indicators are provided to select and display the functions of the ASCOR
3000-524 Module’s operating environment.
3.1 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.
3.2 LEDs
The following LEDs are visible at the Module’s front panel to indicate the
status of the module’s operation:
3.2.1 “BUS” LED
This green color LED is normally off and will flash on when the module is addressed by the system.
3.2.2 “PWR” LED
This red color LED is normally on when the Module is Powered up.

Chapter 4 Internal Settings
The following items are inside the module and can be reached by removing the side cover.
4.1 Fuse
The ASCOR VXI 3000-524 uses a 10 Amp fuse in the +5 Volt line and is located on
the Mother Board (MB) assembly.
4.2 VXIbus Interrupt Level Selection
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”.

Programming
The Model 3000-524 is a VXI register based module. The switch paths are controlled via
VXIMAXTM which is the 16/32 bit data controller. The Model 3000-524 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.
For example:
To close relay K1 set the register bit 0 to a "1."
