Description

Truth tables

When using a COMMAND module with the SELECT, Wavelength or profile

selection is based on truth table results from a combination of the input signals.

The result determines the wavelength of a channel or entire profile as configured

in CONTROL. Examples of this are described in section

“Signaling and CONTROL

configuration” on page 71

Connect to a

SuperK SELECT

system

40-pin cable

The COMMAND module includes a straight through 40-pin cable which must be

connected from the COMMAND module to the ERD’s Modulation connector (see

“Modulation connector” on page 25

Figure 47

shows the cable connected from the COMMAND module to the ERD.

Caution:

Ensure all SuperK system modules are powered OFF before connecting

the COMMAND module
