• 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.
