Pcb-40Ead Board - Canon CXDI-40G COMPACT Service Manual

(4) Temperature detection
The ambient temperature is detected by thermal sensors on the PWB, and if the prescribed
temperature has been reached, a warning, etc. is displayed.
A warning appears when the thermal sensor detects 48 °C (exposure remains enabled), and
an error occurs when it detects a temperature of 49 °C or more (exposure is disabled).
(5) Serial communication
Communication with an externally connected general-purpose terminal is enabled under the
RS-232C standards. (Debugging applications)
(6) Ready lamp control
(7) Log recording
The power-on time, number of exposures, exposure sequence and other data are recorded in
the flash ROM. Logs can be read out by serial communication via Ethernet.
(8) Sensor information storage
The data unique to the sensor is stored in the flash ROM. It can be read out to an external
device using commands via Ethernet.
(9) Remote updating
The firmware and HUB41 PLD codes are updated from the control PC via Ethernet.
