Connect GND signal lines to common ground of the master.
Caution
If the reserved pins are used for any purpose, compatibility with future versions
of the SKB module can be compromised.

Using SK / SP Emulation Mode

The SKB switch can be run in a mode that emulates operation of the SK and SP product line. A
hybrid, parallel connector cable must be constructed. Contact JDS Uniphase for instructions on
cable pinouts.
Simultaneous operation of serial and parallel interface is not supported.

Using the Switch

Voltage Levels

All parallel interface signals are TTL compatible. The active state of each signal is outlined in
Table 8.
data line 7; most significant bit (MSB)
STROBE input, active low:
high-to-low pulse = read data lines and home line
high = ignore state of data lines and home line
This line is internally pulled high via 10 k ohm resistor to 5 V DC
