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.
