You can cascade up to 16 VP-4x8 units with control from a PC or serial controller
(see Figure 10 ).
To cascade up to 16 individual VP-4x8 units via RS-485, do the following:
1. Connect the VGA/UXGA sources and acceptors, as Section 5.1 describes.
2. Connect the RS-232 (or RS-485) port on the first VP-4x8 unit to the PC
using the null-modem adapter provided with the machine (recommended),
as Section 5.2 describes.
3. Connect the RS-485 terminal block port on the first unit to the RS-485 port
on the second VP-4x8 unit and so on, connecting all the RS-485 ports.
4. Set the DIP-switches, as shown in Section 5.5 :
 Set the first VP-4x8 unit as Machine # 1 and the following 15 VP-4x8
units as Machine # 2 to Machine # 16, according to Section 5.5.2

Set DIP 8 ON on the first and last VP-4x8 units (terminating the
RS-485 line at 120
Ω). Set DIP 8 OFF on the other VP-4x8 units

Set DIP 5, DIP 6 and DIP 7 OFF on all VP-4x8 units
