6.3 Controlling via RS-485
You can control a VS-808YC unit via an RS-485 controller, for example, a
PC (equipped with an RS-485 interface) or a Master Programmable Remote
Control system such as the Kramer RC-3000.
To connect an RC-3000 to a VS-808YC unit (see Figure 5):
1. Connect the RS-485 terminal block port on the RC-3000 to the RS-485
port on the VS-808YC unit, as follows:
 Connect the “ A” (+) PIN on the RS-485 rear panel port of the RC-3000
to the “ A” (+) PIN on the RS-485 rear panel port of the VS-808YC unit
 Connect the “ B” (-) PIN on the RS-485 rear panel port of the RC-3000
to the “ B” (-) PIN on the RS-485 rear panel port of the VS-808YC unit
 If shielded twisted pair cable is used, the shield may be connected to
the “ G” (Ground) PIN on one of the units (for example, on the
RC-3000)
2. Set the VS-808YC unit as MACHINE # 2, according to Table 5 (that is,
DIP 1, DIP 2, and DIP 3 OFF, and DIP 4 ON), and set the other
DIP-switches on the VS-808YC unit, as follows:
 Set DIP 5, DIP 6, and DIP 7 OFF
 Set Dip 8 ON (for RS-485 Line Termination with 120)
