Crimp type terminals
Falling off of connections is one of communications failures. Terminate the communications cable with
crimp type ring or spade terminals with an insulation sleeve. (The terminal screws of KR2S series
graphic recorders are M4mm and the terminal screws of the line converter are M3.5mm.)
6-1-5
Attach a termination resistor
For using the RS-485 communications, mount a 100 Ω resistor to the KR2S series graphic recorder
connected at the final end. (For details, see Section 4-3)
[A general metal film resistor can be used. The resistor (sold separately) is available at CHINO.]
However, there are also environments where a communication error cannot take place easily without the
termination resistor attached

Number of this unit connectable
Up to 31 sets
Caution
The distance and the number that can be communicated in the high quality
according to the kind of the communications cable used or the connected
equipment are different though communication IC in accordance with each
communication standard is used about connected the number.
Especially, please note that the number that can be connected becomes ten
or less when the equipment using communication IC that conforms only to
RS-422A standard is connected with the same communication line as KR2S.
