6.6.2 Connecting the ETHERNET Port via a Network Hub (Straight-Through
Cable)
You can connect the Ethernet port of the
VP-26
to the Ethernet port on a
network hub or network router, via a straight-through cable with RJ-45
connectors.
6.6.3 Control Configuration via the Ethernet Port
To control several units via the Ethernet, connect the Master unit
(Machine # 1) via the Ethernet port to the LAN port of your PC. Use your
PC initially to configure the settings (see section
6.6
).

Controlling via RS-232 and RS-485
You can cascade up to eight
VP-26
units with control from a PC or serial
controller.
To cascade up to eight individual
VP-26
units, via RS-232 and RS-485, as
illustrated in
Figure 13
, do the following:
1. Connect the video sources and acceptors, as well as the appropriate audio
sources and acceptors, as described in section
6.1
.
2. Connect the RS-232 port on the first
VP-26
unit to the PC using the null-
modem adapter provided with the machine (recommended), as section
6.4
describes.
3. Connect the RS-485 terminal block port on the first
VP-26
unit to the
RS-485 port on the second
VP-26
unit and so on, connecting all the RS-485
ports.
4. Set the DIP-switches, as section
6.8.1
describes. In particular:
Set the first
VP-26
unit as Machine # 1, the second unit to
Machine # 2, and so on - up to Machine # 8 for the eighth
unit
Set Dip 4 ON on the first and last
VP-26
units (terminating
the RS-485 line at 120
Ω
). On the other units, set DIP 4 OFF
