CAN
The CAN bus is used for PC communications during testing, calibration and
firmware upgrades, and for communicating to the ADL or M800.
The following data is transmitted by the E888/E816 at 200Hz:
• Thermocouple temperatures
• Analog input voltages
• Digital input frequencies
The following data is transmitted by the E888/E816 at 50Hz:
• Cold junction compensation temperatures
• Digital input states
• Output driver faults
• Internal temperature
• Internal voltages (-5v, 8vAux, 5vAux, Vbat, 4.5v)
• E888 status flags
• E888 firmware version
The following data is received by the E888/E816 from the ADL:
• PWM outputs frequency and duty cycle
• PWM outputs disable
Firmware Upgrades
At times MoTeC may release Firmware upgrades for the E8xx Expander units.
Upgrades are performed over the CAN bus using the Dashsend utility with a
MoTeC CAN cable.
The Dash Manager installation adds an icon to the Start menu to perform the
E888 firmware upgrade.
