Item Sub-item Specification
External
control
input
Usage RMTRESET, RMTSHTDN (GENDI), GENDI0,
GENDI1, and GENDI2 (RMTPWRON) (*1) (*2)
Electrical
interface
Interface Non-voltage transistor contact
Contact current 1 mA/point
Applicable load • Relay (gold-plated twin contact)
• Switch
• Isolated open collector
External
control
output
Usage CPUSTOP, WDTTO, PSDOWN, MCALL, GENDO0,
GENDO1, and GENDO2
Electrical
interface
Interface PhotoMOS relay contact
Load voltage Up to 40 VDC (external power supply required)
Load current Steady-state : Up to 0.1 A/point
Inrush : Up to 0.6 A/point, 100 ms
Dielectric strength 250 VAC, one minute
Applicable load • Relay (clamp diode required)
• Buzzer
• Indicator
• Semiconductor device
(*1) RMTSHTDN and GENDI use the same contact (switched by the RAS software setting).
RMTPWRON and GENDI2 use the same contact (switched by the jumper pin setting). For details,
see “6.6 Enabling the Remote Power On Function”.
(*2) When you use an RMTPWRON function, make sure no noise is added to the external contact.
If the contact is closed for 15 ms or more during the soft power off mode due to noise or other
reasons, the power may be turned on unexpectedly. As a side note, while the OS or BIOS is running
after power on, the RMTPWRON function is disabled and the contact can be used as a GENDI2
input.
