5.3 Controlling via RS-485
You can control a VS-66FWunit via any RS-485 remote controller or a PC (equipped with an RS-485 interface).
To connect an RS-485 remote controller to a VS-66FW:
1.Connect the RS-485 port on the RS-485 remote controller to the RS-485 ports on the VS-66FWunit, as follows:
Connect the “A” (+) PIN on the RS-485 remote controller to the “+” (A) PIN on the RS-485 port of the VS-66FWunit
Connect the “B” (-) PIN on the RS-485 remote controller to the “B” (-) PIN on the RS-485 port of the VS-66FWunit
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 RS-485 remote controller)
2.Set the SETUP dipswitches on the VS-66FWunit as follows:
Set the first VS-66FWunit to MACHINE # 11
Set the second VS-66FWunit to MACHINE # 21 and set DIP 8 to ON, terminating the RS-485 line2

Function | DIPS | Description |
Machine # | 1, 2, 3, 4 | Determines the position of a unit in the sequence (see section 5 .4.1) |
Reserved | 5 | OFF |
Reserved | 6 | OFF |
Reserved | 7 | OFF |
RS-485 Termination | 8 | ON for RS-485 Line Termination with 120; |
| | OFF for no RS-485 Line Termination |
1 See Table 3
2 The RS-485 line must also be terminated at the remote controller. Refer to the remote controller’s user manual for details of how to terminate the RS-485 line on the remote controller
