VIS-CAM System
6.3 X2: J-panel connection to Camera 1
Figure 67. Board and camera J-panel connection to camera 1.
6.3.1 Functionality
Power and data connection to the EN camera. The 24V power supply for all camera functions
(Camera, I/O Board, light and heaters), Ethernet and RS485 data communication is connected by
means of this connector.
6.3.2 Connector specification
Connector type: 16 pole WAGO pluggable terminal block
Connector on board: WAGO 734-246
Cable part: WAGO 734-216
6.3.3 Connector signal specifications
6.3.3 (a) Lane Controller interface
Description
RS485 two wire half-duplex multi-drop communication network. The I/O Board has connections for
daisy chain configuration. The two signal pairs (RS485D+ and RS485D-) can be reversed.
Signal levels:
Standard RS485 communication levels.
Electrical interface on the J-Panel:
The signals are connected to J-Panel X15 pin 4 and 5. There are termination resistors on the board.
See Figure 49 on page 53 for a description of the signal path.
6.3.3 (b) Trigger output
Description
The trigger output is balanced and the driver is a RS485 transmitter (LTC1480).
Signal levels
The signals are standard RS485 levels. The specification below is taken from Linear Technologies
datasheet for LTC1480:
