MoTeC Introduction 1 Introduction This manual describes the functions and specifications of the E888/E816 expander modules and their configuration for use with a MoTeC ADL. These devices offer additional inputs and outputs into the ADL via a CAN connection. ECU Manager software is currently being developed that will allow the M800 family of ECUs to read information from the E888/816. This manual includes information on connecting a single expander unit to an ADL or ADL2.

2 Overview Overview The E888 has the following inputs and outputs: • 8 Analog voltage inputs (AV 1-8) • 8 Thermocouple inputs (TC 1-8) • 2 Cold junction compensation thermistor inputs (CJC 1-2) • 4 Digital inputs (DIG 1-4) • 2 Switch inputs (DIG 5-6) • 8 PWM outputs (Aux 1-8) The E816 has the following inputs and outputs: • 16 Analog voltage inputs (AV 1-16) • 2 Thermistor inputs (CJC1-2) • 4 Digital inputs (DIG 1-4) • 2 Switch inputs (DIG 5-6) • 8 PWM outputs (Aux 1-8) The E888 uses the two part 60 pin c

MoTeC Inputs 3 Inputs E888 Thermocouple Inputs (TC1 – TC8) The E888 has eight calibrated and compensated type K (-200 to 1250ºC) thermocouple inputs. Thermocouple inputs are calibrated during production. Note that the thermocouples numbered TC1 – TC8 correspond to pins AV9 – AV16 in the Dash Manager Input pins setup.
PAGE 6
4 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 – 4 can only be calibrated to measure frequency.

MoTeC Inputs 5
PAGE 8
6 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
MoTeC Outputs 7 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. Frequency for PWM1/3/5/7is adjustable from 8Hz to 5kHz. Duty cycle for PWM2/4/6/8 is adjustable from 0 to 100% in 20 steps.

MoTeC Outputs The tab for Expander Output configuration can be found under the Dash Manager menu item ‘Functions – Auxiliary Outputs’.
PAGE 12
10 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. Note that appropriate control channels will need to be generated for these functions. See the ADL Manual for more details on configuring outputs.
PAGE 13
MoTeC E8xx Diagnostic Information 11 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. Go to ‘Inputs – Communications’ and click on a blank CAN tab. Then ‘Select’ the template “Expander Diagnostics”.
PAGE 14
12 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’. This is very useful for testing wiring and sensors, and even determining which sensors are connected to which inputs.
PAGE 15
MoTeC E8xx Diagnostic Information 13 100% 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.

14 Communications Communications CAN The CAN bus is used for PC communications during testing, calibration and firmware upgrades, and for communicating to the ADL or M800.

MoTeC Appendices 19 Appendix D: CAN Wiring – Multiple Device The CAN bus should consist of a twisted pair trunk with 100R (0.25Watt) terminating resistors at each end of the trunk. 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.
