Page 3: Introduction
It is possible to connect a second expander unit to an ADL and a third or even fourth unit to an ADL2 – please contact your MoTeC dealer for details in these situations. -
Page 4: Overview
2 Switch inputs (DIG 5-6) • 8 PWM outputs (Aux 1-8) The E888 uses the two part 60 pin connector also used by the M400, M600 and M800 ECUs. The E816 uses a 66 pin Autosport connector, the same as that used by the... -
Page 5: Inputs
130 023/026 sensors to read from -30ºC to 150ºC. Analog Voltage Inputs (AV1 – AV8 or AV1 – AV16) The E888 has eight 0-5V analog voltage inputs (AV1 to AV8), while the E816 has sixteen inputs (AV1 to AV16). These are suitable for Potentiometers, voltage output sensors and variable resistance (temperature) sensors (these require an external pull-up resistor to 5V). -
Page 6: Input Pin Configuration (Adl)
Inputs Digital Inputs (DIG1 – DIG 4) DIG1 to DIG4 may be used to measure frequency. The frequency measurement range is approximately 1Hz to 5000Hz. Digital inputs should be pulled to ground as the inputs have an internal 2K7 to 12V pull-up resistor. Note: Digital Inputs 1 –... - Page 7 MoTeC Inputs...
- Page 8 Inputs E888 Thermocouples Thermocouple inputs 1 – 8 correspond to Expander Analog inputs ExTC1 to ExTC8. The calibration used for these inputs is “E888 Expander Thermocouple” and can be found in the ‘Select Calibration’ list.

Page 9: Outputs
MoTeC Outputs Outputs Both the E888 and E816 include 8 Auxiliary Outputs that are individually controllable for frequency and duty cycle. They are known as PWM – Pulse Width Modulated – outputs. The outputs are in two groups (odd and even) with different characteristics as follows: Duty cycle for PWM1/3/5/7 is adjustable from 0 to 100% in 255 steps. - Page 10 Outputs...
- Page 11 MoTeC Outputs The tab for Expander Output configuration can be found under the Dash Manager menu item ‘Functions – Auxiliary Outputs’.
- Page 12 Outputs The E8xx outputs can now be configured the same way as the ADL Auxiliary outputs by selecting an output and then setting the control channels and parameters. Ie: Outputs can be on/off, controlled by frequency, duty cycle or a combination of frequency and duty cycle.

Page 13: E8Xx Diagnostic Information
MoTeC E8xx Diagnostic Information E8xx Diagnostic Information Additional status information is available from the E8xx along with the state of the 2 Switch Inputs and the temperatures measured on the 2 thermistor inputs. This information can be accessed by selecting an additional CAN template in the Dash Manager communications setup. -
Page 14: Test Analogue Inputs
E8xx Diagnostic Information Test Analogue Inputs It is possible to view the current ‘live’ voltages on the expander’s analogue inputs using a PC connected to the E8xx via an ADL. In Dash Manager select the menu item ‘Online – Test – Analogue Inputs’. Then click on the tab ‘Expander Analog’. - Page 15 MoTeC E8xx Diagnostic Information 100% duty cycle corresponds to the output fully On (Low Voltage), 0% duty cycle corresponds to the output fully Off (High Voltage). The frequency should be chosen to suit the device.

Page 16: Communications
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. See the item under ‘Start – Programs – MoTeC – E888 and E816 Expander... -

Page 21: Appendix D: Can Wiring - Multiple Device
The preferred cable for the trunk is 100R Data Cable but twisted 22# Tefzel is usually OK. The maximum length of the bus is 16m (50ft) including the MoTeC CAN Cable (PC to CAN Bus Communications Cable) CAN Devices (such as MoTeC ADL, BR2 etc) may be connected to the trunk with up to 500mm (20in) of twisted wire. -
