This Address Byte is sent to the optical module being addressed.

 

 

 

 

See the Optical Attenuator Operation section of the manual for the

 

 

 

 

operation of the Address register.

 

 

 

 

To operate the modules correctly, the SM8000 must be loaded

 

 

 

 

with a valid Address in the Address Register. The SM8000 is hard

 

 

 

 

coded with the optical modules default address of 73 => 49h and

 

 

 

 

may be used to generate the address required in the command

 

 

 

 

string. This is the address of all attenuators as shipped from the

 

 

 

 

factory. During the programming of the optical module, the

 

 

 

 

programmer may wish to omit sending the module’s address over

 

D6-D0

Address Byte to

 

the VXI Bus, letting the SM8000 generate the default address that

 

 

is used in the command string. This could possibly increase

 

Optical Module

 

 

 

 

throughput, by decreasing VXI Bus traffic, if the modules are

 

 

 

 

 

 

 

 

receiving many commands. Although, this is only true if the

 

 

 

 

optical module’s address is not changed by the user. It is

 

 

 

 

recommended that the optical module’s address be left at 49h. If

 

 

 

 

the address is to be changed, IT IS IMPERATIVE THAT THE

 

 

 

 

NEW ADDRESS BE WRITTEN DOWN. Failure to do so will

 

 

 

 

result in an inability to control the module. All 4 possible modules

 

 

 

 

may have the same address. The SM8000 controls them on

 

 

 

 

separate internal busses.

 

 

 

 

If setting the module’s address, the address byte must be set prior

 

 

 

 

to writing to the optical module’s data (attenuation level) register.
