02 - MIM Inputs / Outputs

Thermocouple inputs

The MIM01 has 2 K-type thermocouple inputs, each input is capable of measuring temperatures from 0 - 1000°C.

Each socket is the standard thermocouple socket format; the Green colour on a thermocouple plug indicates a K-type

thermocouple, +ve (green wire) on the thin spade terminal.

See the Specification table for full thermocouple specifications

Status lights:

• Green light indicates a functioning thermocouple is connected.

• Red light indicates no thermocouple connected or a problem with the thermocouple.

Analogue Inputs

All of the analogue inputs are non-opto isolated 14 bit 0 - 14 V inputs, and they are all non-differential inputs that share the same ground.

An example of how to connect an isolated individual potentiometer is shown below.

Connecting to a potentiometer already installed on a car, such as a throttle potentiometer, would only require the output signal from the pot and the earth to be connected to the MIM01 as the pot gets its power from the car.

Digital Inputs

The digital inputs are optimised to suit certain applications.

• Digital Input channel 1 Optimised for event marking due to its internal 100 Kohm pull up resistor, with a simple switch that connects the input pin to ground. The low state is below 4 V so it can also be used as a TTL pulse input, such as fuel flow sensor inputs.

https://racelogic.support/

01VBOX_Automotive/

04Modules_and_accessories/

Mini_Input_Module/

• Digital Input channel 2

Optimised for a zero crossing AC input signal such as a Wheel speed signal or engine crankcase signal.

• RPM input, Digital input 3 Optimised for low-tension ignition coil signals.

See the Specification table for full digital input specifications

The Name and Units for each Digital input channel can be configured. There are also other modes and options configurable depending on the Digital Input channel.

03 - MIM Connecting to VBOX Mini

To connect the MIM01 to a VBOXMini, an RLCAB045 cable must only connect to the DATA2 socket, because this data connection is an RS232 serial data link that is only present in the DATA2 socket. The SC light under the connector will indicate when there is serial communications present between the MIM01 and the VBOXMini.

On the VBOX Mini, the AUX connector must be used.

After each power up, the Input Module Screen on the VBOX Mini must be accessed in order for the VBOX Mini

to recognise the presence of the MIM01. After this has been done, then any of the VBOX Mini screens can be

used, but this must be done or the MIM01 channels will not be logged.

Configuring the MIM01 when connected to a VBOX Mini

When a MIM01 is connected to a VBOX Mini, the VBOX Mini will automatically log all of the input channels.

1. Connection - Selected com port, refresh and disconnect buttons.

2. Module Information – Serial number and installed firmware version of connected unit.

3. Load/Save - Load/Save settings from/into a Racelogic setting file (.RSF). This allows setups to be kept for future

use.

4. Language - Select an operating language.

5. Write to unit - After making changes to setup, the write to unit button must be selected to upload settings.

Settings

1. Baud Rate - Baud Rate sets the bit rate of the CAN message transmission.

Selectable baud rate options are: 1000 kbit/s 500 kbit/s (default) 250 kbit/s 125 kbit/s

https://racelogic.support/

01VBOX_Automotive/

04Modules_and_accessories/

Mini_Input_Module/

Page 24

2. Data Format - This option allows you to change the format in which data is transmitted in stand-alone mode.

The available Format options are: IEEE 32 bit float

32 bit unsigned integer 16 bit signed integer 16 bit unsigned integer Racelogic float 32 bit signed integer

3. Modes - In the settings tab, the user has the option to configure the MIM into one of three CAN modes to suit

different applications.

Racelogic Polled - This mode should be set if the module is to be used with a Racelogic VBOX. All the CAN parameters are set to work with the Racelogic VBOX CAN protocol. In this mode no other parameters need be set or indeed will have any effect.

User Polled - This mode allows a customer’s own data logging system to poll the module for data using the CAN bus. In this way, the output timing of the sensor can be synchronised with other CAN information. The following parameters are all used and so must be set: Baud rate (Selectable from 125 kbit/s, 250 kbit/s, 500 kbit/s or 1 Mbit/s) Extended Identifiers (OFF or ON) Request Identifiers (Identifiers used to request data from the sensor) Response Identifiers (Identifiers used to transmit data from the sensor)

Timed - In this mode the module will send CAN data at intervals determined by the Timer value. The following parameters are all used and so must be set: Timer (Time interval in milliseconds between output data) Baud rate (Selectable from 125 kbit/s, 250 kbit/s, 500 kbit/s or 1 Mbit/s) Extended Identifiers (OFF or ON) Response Identifiers (Identifiers used to transmit data from the sensor)

4. Extended Identifiers - Extended Identifiers can be set either ON or OFF. If they are off the CAN identifier type

will be standard (11 bit). If they are on the CAN identifier type will be extended (29 bit). The Standard Identifier type allows 2048 different CAN message identifiers or message “names”. The Extended Identifier type allows 436207616 different CAN message identifiers. The identifier type should be set to match the CAN data logging equipment that the module is connected to.

Entering a value of “off”, “OFF” or “0” will turn Extended Identifiers off. Any non-zero value, “on” or “ON” will turn Extended Identifiers on.

https://racelogic.support/

01VBOX_Automotive/

04Modules_and_accessories/

Mini_Input_Module/

Page 25

5. Conversion Identifiers - The Conversion Identifier only has an effect in User Polled Mode. When the module

receives this identifier with zero data bits it will sample its inputs. This is set as separate command to a data request identifier so that it gives the module time to make a data conversion before having to send the data on the CAN bus.

6. Timer - The timer value is in milliseconds (ms). A smaller value means data will be sent more frequently, a larger

value means data will be sent less frequently. The range of values that can be entered is 0 to 65535 however the minimum value that should be entered is 10. Below this value data values may be repeated on successive cycles. If a value of 0 is entered the module will change it to 1 on the next power cycle.

Frequency output can be calculated as follows: Freq = (1/Timer) * 1000 The Timer value for a required frequency can be calculated as follows: Timer = (1/Freq) * 1000 Some example Timer values are shown against the frequency output.

Timer Value Frequency

10 100

50 20

100 10

400 2.5

1000 1

7. Pack Data - Byte-packing can be used to reduce the number of CAN messages required to transmit MIM data.

When turned OFF, each of the eight channels will be sent using a separate CAN Identifier message, each with a Data Length Code (DLC) of 4 bytes. When Byte packing is turned ON, channels will be combined into pairs for transmission over CAN, each message with a DLC of 8, as follows:

CAN ID First 4 Data Bytes Last 4 Data Bytes

CAN ID set for Channel 1 Channel 1 Data Channel 2 Data

CAN ID set for Channel 3 Channel 3 Data Channel 4 Data

CAN ID set for Channel 5 Channel 5 Data Channel 6 Data

CAN ID First 4 Data Bytes Last 4 Data Bytes

CAN ID set for Channel 7 Channel 7 Data Channel 8 Data

Channels

Each input channel has a drop down associated for configuring channel specific attributes.

Digital input channels include an 'edge detection' option. This determines whether the frequency is measured from the RISING or FALLING edge of the signal.

The Digital input channels 1 & 2 also include a Mode option. Please see the section ‘Digital inputs’ for more details.

Scale and Offset

For more information on calculating scale and offset, Click Here.

Request and Response Identifiers

The Request Identifiers only have an effect in User Polled CAN Mode. If a CAN message is received by the MIM01 that matches a Request Identifier then the MIM01 will respond by sending the corresponding channel data on the corresponding Response Identifier. Note: All channels can be set to the same Request Identifier, if desired – this means

that on receipt of a single CAN message the MIM01 will respond with all channels of data. The Response Identifiers

https://racelogic.support/

01VBOX_Automotive/

04Modules_and_accessories/

Mini_Input_Module/

Page 27

MUST all be different.

In Timed Mode the channel data will be sent at intervals with the corresponding Response Identifier – the Request Identifiers have no effect.

When using Standard Identifiers the maximum value for the identifiers is $7FF. Entering a value higher than this may result in unexpected results.

08 - MIM Firmware Upgrade

It is recommended to check the web site periodically for updates. To upgrade the MIM firmware, download the following from the RL website.

1. The MIM latest firmware file (.RUF extension file)

2. Racelogic Upgrader software

Connect Data 1 port on the MIM to the PC via the a RLCAB001 serial cable, and apply power to the MIM.

Double click on the .RUF upgrade file, which auto runs the Upgrader software. Ensure the correct COM port is selected in Racelogic Update software, then hit ‘upgrade' to start the procedure.

When this is complete, powering the MIM off and back on will complete the process.

Note: To confirm which COM port is assigned to the MIM, check device manager.

Ensure that other software which may try and use the COM port communications, such as VBOX Tools, is closed.
