5.0.1 Input/Output ports
Referring to the different models, the video signal input/output jacks are formed by the 4th
row and 8th row BNC female connectors. The BX-3088 video signal input/output jack channels
are numbered from left to right as NO.1 to NO.8 (in two rows). The connectors are indicated
from upper to lower as R, G, B, H, and V signal terminals. Refer to the drawing on the housing
for other types of connectors.
Different models of BX matrix systems provide a different number of input/output
connectors where users can connect to different video equipment including CD/DVD players,
graphics workstations, and number display. The output connectors can be connected to projectors,
video recorders and displays.
5.0.1.1 Video Connecting Cable
The BX matrix supports various types of AV video frequencies and VGA signal sources.
The AV signal source equipment must have RGBHV signal output terminals; the VGA signal
source must have RGBHV signal output terminals.
The BX matrix BNC connector connection is shown in Figure 5-2 below:
Figure 5-2 BNC Connection
If the VGA signal source equipment has no RGBHV output terminal, you are recommended
to use a VGA-RGB converter to get high quality RGB output signals.
Pleas use a 5-wire RGB signal cable for connection to input/output equipment. Connect the
R (Red), G (Green), B (Blue), H (Horizontal sync) and V (Vertical sync) BNC connectors of the
signal source equipment output terminal separatedly to the same channel RGBHV connectors of
the BX matrix inputs. Also, connect the RGBHV connectors of the BX matrix outputs to the
RGBHV input connectors of the output equipment through a 5-wire RGB signal cable.
NOTE: The RGBHV connectors at both ends of the signal cable must correspond to each
other, otherwise loss of color reproduction and even no signal output could happen.
5.0.2 BX Matrix System and Control Computer Connection
Use the RS-232 connecting cable to connect the computer serial port (COM1 or COM2) to
the RS-232 communication port of the BX matrix host. The computer can then be used to control
the BX matrix after installation of application software.
