RJ45 wiring details for the GX 3016:
7.6
Connecting an RS232 serial control device to the Data Link
An RS 232 control device should be connected to pins 3 and 4 of the Console 2 socket. Where both a control device
and a bus console need to be connected to the same socket, a BOUYER EL 720 type adapter should be plugged into
the RJ45 to enable the bus console and the control device to be connected together.
7.7
RS232 socket on the front panel
The DN 3816 matrix is fitted with an RS232 port so it can be connected up to a PC. Use the 9-pin SUB-D male-
female connector supplied to connect the PC to the DN 3816 matrix
Female connector RS232 pinout (DN3816 side)
7.8
Logic GPI (General Purpose Input) wiring
The DN 3816 matrix has 8 opto-coupled logic general purpose inputs (or logic GPIs). Switches or relay contacts of
external equipment may be connected directly to the GPIs to achieve the operation required.
The GPI connector block
The DN 3816 can power up to eight GX 3016 consoles via the RJ45. If the installation consists of more
than eight consoles, then an external power supply should be added, to be connected to the Jack socket
on the consoles.
Using GX 3016 consoles on bus 1 and/or 2 means that audio inputs 5 and/or 6 cannot be connected to
any other sources, otherwise the system will not work correctly.
