Chapter 3 Functional Description
3.1 Introduction
This manual provides the necessary information for the operation and maintenance of the Model 4506
General Purpose VXI Switch Module.
3.2 General Description
This card assembly contains twelve 1x4 single wire high power switch multiplexers (trees). These 1x4
multiplexers is capable of carrying 10 amps of load. In each of the 1x4, there is a default position which
is normally closed. During initial turn on or after a reset to the card, the switch trees will be set to the
default position. This will be pole 1 of each tree to the common will be closed. This card assembly fits in
an ASCOR’s series 4000 VXI host modules which can be a 3 wide to 8 wide VXI module with the capacity
for six to 17 card assemblies. This card occupies two 0.5 inch slots or 1 inch width. This allows of ease in
design of complex switch systems. The Series 4000 host VXI module contains sixteen 2-wire analog back
plane to allow connections between card assemblies without the need of external cabling. This
architecture produces a high performance switch system without the usual custom designs or external
wiring and integration efforts. The interface and mechanical construction of the Series 4000 VXI module
and card assemblies meets the specification of the VXIbus System Specification, rev. 1.2 and 1.3.

Contact Power Rating (Resistive): 280 W or 5000 VA
The Model 4506 is a VXI register based card assembly design to be used with the ASCOR Series 4000
host VXI module. The switch paths are controlled by a high speed interface called VXImax™ is a 16/32
bit data controller. The Model 4506 can be programmed in 16 bit or 32 bit wide data format. 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.
