Chapter 2 Functional Description
2.1 Introduction
This manual provides the necessary information for the Model 4208 card assembly.
2.2 General Description
This card assembly contains six 1x8 dual wire switch multiplexers (trees). 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 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.
note: This card assembly requires a ASCOR Series 4000 host VXI module. It is not a stand alone VXI
module.

Chapter 5 Register Map
5.1 Introduction
The Model 4208 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 4208 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.

ASCOR 4208 VXI Card Assembly Module Programming Guide
The base offset address for the Model 4208 is 8000h. The total offset of the card is dependent
