OPERATION
With the Receiver and Transmitter Units connected, the Extender System is ready for operation. The Transmitter can
be powered up at any time. It does not have to be coordinated with the power up of the PC.
If the Transmitter is powered up after the PC is powered up, or if it is powered down while the PC remains powered
up, it is possible that the keyboard status indicators, Caps, Num, and Scroll Lock, are "out of step". This can be corrected by
operating any one of the respective keys. This will cause a "refresh" of these indicators.
THEORY OF OPERATION
The VIP-380 Extender System uses a proprietary RS-232 protocol to communicate between the Transmitter Unit and
the Receiver Unit. The RS-232 protocol permits essentially unlimited distance between the two units by use of standard RS-
232 techniques to extend distance. Keyboard and mouse data are multiplexed onto one data stream for transmission.
Transmission data rate is 9600 baud. The Transmitter will assert RTS (DB9 pin 7) when either the remote keyboard and/or
mouse are active. The Transmitter will also send data only when incoming CTS (which is checked at DB9 pin 8) is asserted.
SPECIFICATIONS
Power
: The Transmitter is powered from an external power supply, supplying 5 volts regulated, rated at 2 A. The Receiver
Unit is powered from the PC.
