||
| 8 | # Communication Interfaces |
||
| 9 | |||
| 10 | IOcan provides multiple communication interfaces for configuration and vehicle integration. |
||
| 11 | |||
| 12 | ## USB |
||
| 13 | * USB-C connector |
||
| 14 | * used for: |
||
| 15 | * device configuration |
||
| 16 | * firmware updates |
||
| 17 | * diagnostics |
||
| 18 | * datalogging |
||
| 19 | |||
| 20 | USB power can also power the device logic for configuration without vehicle power. |
||
| 21 | |||
| 22 | ## CAN Interfaces |
||
| 23 | * 4 independent CAN-FD interfaces |
||
| 24 | * fully compatible with CAN 2.0B networks |
||
| 25 | |||
| 26 | Typical uses include: |
||
| 27 | |||
| 28 | * ECU communication |
||
| 29 | * transmission communication |
||
| 30 | * additional vehicle networks |
||
| 31 | * diagnostic networks |
||
| 32 | |||
| 33 | CAN termination can be enabled or disabled depending on network topology. |
||
| 34 | |||
| 35 | # Analog Inputs |
||
| 36 | |||
| 37 | IOcan provides multiple analog inputs that can be used to read vehicle signals or sensors. |
||
| 38 | |||
| 39 | Total inputs: 11 |
||
| 40 | |||
| 41 | ## 0–12 V Inputs |
||
| 42 | * 7 channels |
||
| 43 | * intended for direct connection to automotive signals such as: |
||
| 44 | * ignition signals |
||
| 45 | * switches |
||
| 46 | * sensor outputs |
||
| 47 | ## 0–5 V Inputs |
||
| 48 | * 4 channels |
||
| 49 | * intended for sensors requiring tighter voltage ranges such as: |
||
| 50 | * pressure sensors |
||
| 51 | * throttle sensors |
||
| 52 | ## Shared Functionality |
||
| 53 | Some analog inputs can also operate in other modes: |
||
| 54 | * digital input mode |
||
| 55 | * resistor ladder input for multiple buttons |
||
| 56 | * frequency input mode |
||
| 57 | |||
| 58 | See [[Configuration Concepts]] for input configuration. |
||
| 59 | |||
| 60 | # Frequency Inputs |
||
| 61 | IOcan supports 4 frequency inputs for pulse-based signals. |
||
| 62 | These inputs share hardware with selected analog inputs. |
||
| 63 | Typical applications include: |
||
| 64 | * engine speed signals |
||
| 65 | * wheel speed signals |
||
| 66 | * vehicle speed sensors |
||
| 67 | * other pulse-based signals |
||
| 68 | |||
| 69 | Signal processing is configurable in software. |
||
| 70 | |||
| 71 | # Digital Outputs |
||
| 72 | IOcan provides 5 digital outputs for controlling external devices. |
||
| 73 | Specifications: |
||
| 74 | * maximum current: 0.9 A per output |
||
| 75 | * outputs share hardware with selected analog inputs |
||
| 76 | Typical uses include: |
||
| 77 | * indicator outputs |
||
| 78 | * relay control |
||
| 79 | * actuator control |
||
| 80 | Output behavior is fully configurable. |
||
| 81 | |||
| 82 | # Transmission Control Outputs |
||
| 83 | IOcan includes dedicated outputs for transmission control. |
||
| 84 | |||
| 85 | # Wake-up Output |
||
| 86 | A dedicated output is provided for the transmission wake-up signal. |
||
| 87 | This output activates the transmission electronics during startup. |
||
| 88 | |||
| 89 | # Integrated Transmission Power Relay |
||
| 90 | IOcan includes an internal semiconductor relay used to power the transmission. |
||
| 91 | |||
| 92 | ## Specifications: |
||
| 93 | * switching type: semiconductor relay |
||
| 94 | * maximum current: 15 A |
||
| 95 | * switched supply: KL30B |
||
| 96 | |||
| 97 | The relay allows IOcan to control transmission power sequencing without requiring external relays. |
||
| 98 | |||
| 99 | Power management logic ensures correct startup and shutdown behavior. |
