WARNING

NOTE

Input characteristics:
Input signal	: Dry contact, open-collector (TTL or transistor) signal
Control functions and signal types:
	• Recording start/stop	level
	• Chart speed change	level
	• Printout messages	trigger more than 250 msec
Signal characteristics	: ON voltage	0.5 V or less (30 mA DC)
	Leakage current in OFF state	0.25 mA or less
	Signal duration	250 msec or more
Input types	: Photocoupler isolation (one line common)
	Internal isolated power source (5 V±5%)
Dielectric strength	: 500 V DC for one minute between input terminals and
	grounding terminal.

To prevent an electric shock, ensure the main power switch is turned off before wiring.

•Use shielded cables for remote control signals to prevent noise pickup. The shield should be grounded at the recorder’s terminal.

•To prevent an emission of electromagnetic disturbances, separate the remote control wires from the power supply and input wires at least 0.1 m. Over 0.5 m is recommended.
