AUDIO UNIT RS-485 port, as illustrated in the example in

Figure 7, do the

following:

• Connect the “A” (+) PIN on the AUDIO CONTROL RS-485 rear panel

port of the VP-747 to the A (+) PIN on the RS-485 rear panel port of the

VP-727A unit

• Connect the “B” (-) PIN on the AUDIO CONTROL RS-485 rear panel

port of the VP-747 to the B (-) PIN on the RS-485 rear panel port of the

VP-727A unit

• If shielded twisted pair cable is used, the shield may be connected to the

“G” (Ground) PIN on one of the units
