4.2 Connection of H-LNK-A Module With Master Station
Always connect a terminating resistor between the DA and DB terminals of the module
to be located at the far end. Use the terminating resistor attached to the Control &
Communication Link master station.
Never use a T-type branch or star connection.
Use a twisted pair cable dedicated to Control & Communication Link Ver. 1.10.
Ground both ends of the shield wire on the twisted pair cable (so that the grounding
resistance is 100
Ω
or less) via the SLD or FG terminal of each module. In addition, the
SLD terminal is internally connected with the FG terminal.
Do not ground the instrument together with other equipment.
Use grounding wires with a cross section of 2.0 mm
2
or more.
CAUTION
To prevent electric shock or instrument failure, turn off the power before
connecting or disconnecting the instrument and peripheral equipment.
