The SM8000 can alternatively drive up to 4 optical multi switch or

 

 

attenuator modules. Module one is addressed by writing a 16-bit

 

 

word to address LA+0x002; module two is controlled by writing

 

 

to address LA+0x004 and so on.

 

 

When controlling the multi switch modules, data bits D4 (MSB)-

 

 

D0 (LSB) are used to pass the channel selection data directly to

 

 

the optical module. See the configuration information for the
