KRAMER: SIMPLE CREATIVE TECHNOLOGY
Connecting a Control Interface
20
To connect an RS-485 connector on one unit to an RS-485 connector on one
or more other switchers (from the series of 16x16 matrix switchers), as
Figure 11 illustrates:
1. Connect the “+” PIN on the first unit to the “+” PIN on the second unit or
other unit
2. Connect the “-” PIN on the first unit to the “-” PIN on the second unit or
other unit
3. If shielded cable is used for an RS-485 connection, connect the shield to the
Ground PIN.
For details about how to configure the vertical sync (if required), refer to
section
9.3 and Figure 17 in section 11.3.1.

Figure 12 illustrates the RS-485 line that connects:
• To the PC via a Kramer Tools VP-43xl Interface Converter
(connect the PC’s 9-pin D-sub COM port to the “RS-232 in” 9-pin
D-sub (F) port on the VP-43xl. Next, connect the RS-485 port on
the VP-43xl to the RS-485 ports on the unit by connecting the
“A” terminal of the VP-43xl to the “+” terminals of the switchers,
and “B” to “-” terminals)
