16-Channel Relay Multiplexer Registers 77Appendix B

Appendix B

16-Channel Relay Multiplexer Registers

Addressing

of VXI A16 address space. Every VXI device (up to 256 devices) is

allocated a 64 byte (32 word) block of addresses. The Multiplexer uses six

of the 64 addresses allocated.

Figure B-1 shows the register address location within A16. Figure B-2

shows the location of A16 address space in the E1300/01 Mainframe and

E1405/06 Command Module.
