1. HDBaseT
it can support Full HD uncompressed video transmit from image device compatible with HDBaseT. Only supports video format
over network cable. Data and sound are not supported.
2. RS232
RS232 input
The communication interface of the RLS W12 projector supports RS232 serial communication.
You can use the RS232 input to connect a local PC to your RLS W12 projector. By this way you can configure and control your
RLS W12 projector from your local PC.
Advantages of using RS232 serial communication:
• Easy adjustment of the projector via PC (or MAC).
• Allow storage of multiple projector configurations and set ups.
• Wide range of control possibilities.
• Sending data to the projector (update).
• Copying data from the projector (backup).

RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of
the commu- nication path between two devices using either D-SUB 9 pins or D-SUB 25 pins connectors.
This standard is used for relatively short-range communications and does not specify balanced control
lines. RS-232 is a serial control standard with a set number of conductors, data rate, word length and type
of connector to be used. The standard specifies com- ponent connection standards with regard to computer
interface. It is also called RS-232-C, which is the third version of the RS-232 standard, and is functionally
identical to the CCITT V.24 standard. Logical ’0’ is > + 3V, Logical ’1’ is < -
3V. The range between -3V an d +3V is the transition zone.
