DMX
DMX-512 Lighting protocol over RS-485 interface. Carries information of 512 channels from a
lighting controller to lighting devices. Standardized by USITT.
RS232/RS422 input
The communication interface of the NJORD series projector supports RS232 and RS422 serial
communication on two different types of input connectors, a Sub-D connector and an USB connector acting as
RS input when connected to an USB input of a PC.
You can use the RS232/RS422 input to connect a local PC to your NJORD series projector. By this way you
can configure and control your projector from your local PC.
Advantages of using RS232/RS422 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.
•
address range from 0 to 255.
•
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 communication 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
component 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 and +3V is the transition
zone.
