Overview
The unique
VP-14xl
RS-232 Port Extender
distributes an incoming RS-232,
RS-485 or USB command as transmitted by a touch screen control system,
personal computer or other type of control system, to up to three RS-232 ports.
This lets you control up to three compatible devices with only one serial port or
RS-232 card.
The
VP-14xl
is specifically designed for use with Kramer switchers and routers,
but can be used with any other equipment which employs RS-232.
In particular, the
VP-14xl
features:
•
One RS-232 input port
•
One RS-485 input port
•
One USB input port
•
Three RS-232 output ports
•
Operation in either Hardware or Software mode
•
DIP-switches to determine the source of the reply command when the
VP-14xl
is in hardware mode
•
DIP-switches to determine the machine number when operating in Software
mode and there are multiple
VP-14xl
units on the RS-485 bus
•
DIP-switches to determine the serial port baud rate (see
Section 6.3
)
In
Hardware
mode, the:
•
VP-14xl
routes the reply from the output port defined by the DIP-switches 2,
3 and 4 (see
Section 6.2
)
•
RS-232 data is passed from any input to all outputs
In
Software
mode, the
VP-14xl
routes the data and reply based on the Protocol
2000 commands received from the PC or other device connected to any of the
inputs (RS-232, RS-485 or USB), see
Section 8
.
To achieve the best performance, we recommend:
•
Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
•
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your
VP-14xl
in a location
free from moisture and away from excessive sunlight and dust
!
Caution:
No operator serviceable parts inside the unit
Warning:
Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Warning:
Disconnect the power and unplug the unit from the wall
before installing
