3. Connect the included interface cable between port P1 (the MSTR port) on the master unit
and port P2 (the SLV port) on the first slave unit.

4. Use the grounding strap provided to connect an equi-potential ground stud on the master
unit to an equi-potential ground stud on the first slave unit.

1. Set the Master / Slave switch in the "up" (MSTR) position.
2. Remove all Master / Slave interface cables from the master unit.
