6.5.2 Connecting the ETHERNET Port via a Network Hub (Straight-Through
Cable)
You can connect the Ethernet port of the
VP-23N
to the Ethernet port on a
network hub or network router, via a straight-through cable with RJ-45
connectors, as Table 7 defines:

6.5.3 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 6.5).
6.6 Controlling via RS-232 and RS-485
You can cascade up to eight VP-23N units with control from a PC or serial
controller.
To cascade up to eight individual
VP-23N
units, via RS-232 and RS-485, as
illustrated in Figure 11, 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-23N
unit to the PC using the
Null-modem adapter provided with the machine (recommended), as section
6.3 describes.
3. Connect the RS-485 terminal block port on the first
VP-23N
unit to the
RS-485 port on the second
VP-23N
unit and so on, connecting all the RS-485
ports.
4. Set the dipswitches, as section 6.7.1 describes. In particular:
Set the first VP-23N 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-23N
units (terminating the
RS-485 line at 120 ). On the other units, set DIP 4 OFF
