Connecting a VP-214DS 4 Channel Automatic XGA Switcher

6.6 Connecting Several VP-214DS Machines
For certain applications, you may need more than just 4 channels for
switching. Cascading
VP-214DS
units enables you to expand the number of
2x1 switchers to be used.
You can cascade up to 8 individual
VP-214DS
units. For example, 3
VP-214DS
units, connected via RS-232 and RS-485, will operate separately,
forming 12 separate 2x1 XGA switchers.
To cascade up to 8 individual
VP-214DS
units (see Figure 9), do the following:
1. Connect the XGA sources and acceptors as section 6.1 describes.
2. Turn ON the power.
3. Connect the RS-232 port on the first
VP-214DS
unit to the PC using the
Null-modem adapter provided with the machine (recommended), as
section 6.2 describes
1
.
4. Connect the RS-485 terminal block port on the first
VP-214DS
unit to
the RS-485 port on the second
VP-214DS
unit and so on, connecting all
the RS-485 ports.
5. Set the Machine dipswitches as follows:
Set the first
VP-214DS
unit MACH. NO. dipswitches to Machine # 1
and the following units to Machine # 2, Machine # 3, and so on – up
to the last connected
VP-214DS
unit (according to Table 8)
Set the RS-485 TERM dipswitch ON on the first (Master) and last
VP-214DS
unit (terminating the RS-485 line) and set it OFF on the
remaining units
1 Or connect via the Ethernet port as section 6.7 describes
