3 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
!
