COBRARTP R7 USB Port Module

COBRARTP-R7-USB-Port-Module-IMAGE

OVERVIEW

Connection and installation in ECU
Installation in the ECU is done using the pin contacts in the chip socket, as shown below, using the example of USDM OBD1.

COBRARTP-R7-USB-Port-Module-FIG 1

To ensure access to the CobraRTP USB port, it is necessary to make a cutout in the ECU case.

Warning: It is worth paying special attention when installing (removing) the board in ECU, as well as during storage, since the type of pin contacts (round) shown in the photo above have low strength and can be prone to kinking under light load or when the board falls without protection.

The Datalog is connected to the ECU (connector CN2) using a cable from the kit, as shown below:

COBRARTP-R7-USB-Port-Module-FIG 2

Note: the colors of the wires are illustrative, the colors of the wires in your case may vary, but the order should match as in the photo above.
The photo on the right shows the pin numbers of the CN2 connector.

As you can see, two data lines are used for the connection – RX and TX, respectively 2 and 4 pin of connector CN2 in the ECU. This is true for both USDM and the JDM region.

Connection to PС

Connect v3.0 Honda Edition to a PC using a standard USB type-B cable. CobraRTP can only connect to a PC, i.e. There is no need to install (connect) the emulator to the ECU, or connect a separate power source.

Connection setup:

After connecting, you should have a new device in the device manager. After that, you need to install USB drivers.
Drivers is necessary downloaded on our website: https://cobrartp.com/en/downloads

Setup USB-Drivers:

Installing USB drivers is standard. To do this, you must run the file “Setup v3.0 USB Driver.exe” and follow the instructions(3). After successful installation of the driver, in the device manager, if there is a connected emulator, two virtual COM ports should appear:

View of the device in the device manager upon successful installation of the driver (port numbers may differ from yours).

Notes:

one of the COM ports is used for RTP (emulation), the second, respectively, for Datalog. It is possible to determine on which port the emulator (RTP) is used, using the CobraRTP Utility (see below).
If for some reason the standard drivers were installed (auto-update), then for stable operation of the system it is necessary to specify the following parameters in the port properties:

COBRARTP-R7-USB-Port-Module-FIG 4

Or reinstall the driver using the official drivers from our website (described above).

For successful installation of drivers it is strongly recommended to disable anti-virus software.

Warning: because the device does not have a protective case, and implies installation in the ECU case, when turned on outside the ECU case, it is not recommended to touch the unprotected current-carrying sections of the device board!

Check connection:

To test the CobraRTP device, you can use CobraRTP Utility. You can download the latest version on our website in the “Downloads” section. The number of the required COM-port for emulation (RTP) will be selected automatically and displayed in the status bar of the program:

COBRARTP-R7-USB-Port-Module-FIG 5

emulator software version.
the number of the active (used) COM-port (for emulation).

Accordingly, the second added COM-port number when connecting the device will be used for Datalog.

AUX Settings
The analog inputs in the device are used as an option (AUX) to expand the capabilities of the limited analog inputs in the ECU. This feature currently works in HTS 2.03 or later & Honda Edition R5.0+

Settings for HTS:

This function is included with datalog.

Also analog inputs (AUX) can be checked and configured in the CobraRTP utility Service – Analog in:

COBRARTP-R7-USB-Port-Module-FIG 9

The voltage will correspond to that specified for one or more channels (1-2-3) between GND.

Select datalog channel mode (USB-BT)
This function is available for versions with Bluetooth module (R6.0B +). To select the dataog mode (channel), use the Service-Settings tab (v2.5+ required):

To switch the mode, you must select the appropriate item and save (the selected mode is saved in permanent memory).

Pssword for BT mode: 1234

Note:

Wireless way of working datalog (BT) is designed primarily to work with the mobile application (TunerView, Linszter Datalog v2), as well as with the Honda Tuning Suite. Performance with other programs is not guaranteed, but possible!
To test the Datalog channel in the “Test” tab, use the USB mode.
Make sure that the correct COM port for BT datalog is selected, there may be several of them and it does not correspond to the COM port for USB mode!

Installing Bluetooth (BT) module

If you have a revision of the R6.0B + board without a preinstalled BT module for datalog, then you can install the BT module yourself. To do this, you need any BT module with the ability to provide the following settings:

speed must be set to: 38400 bps/s (baud)
power supply voltage (Vcc-GND): 5V

The connection diagram is shown below:

Note: the direction of the TX / RX lines is shown inverse, i.e. the way the pins of the bluetooth module should be located. For example HC-05 is fully compatible.

Dual-Mode:

CobraRTP Honda Edition starting with revision R7 allows the upload and use of two different base maps (Bin). For this, a “Dual-mod” jumper is provided on the board, with the help of which the firmware is selected (memory block):

Upload two ROMs (basemap):

The firmware download is performed in the following order:

Upload ROM1 (jumper installed – contact closed)
Upload ROM2 (jumper removed – contact open)
Thus, by closing and opening the contact of the “Dual-Mod” jumper, we select a memory block and upload different firmware into different areas of the emulator’s memory.

Using:
For use, you can select the desired memory area, i.e. ROMx using the jumper state (closed/open), in accordance with the order of the uploaded. For the convenience of switching, you can use a toggle switch brought out at a short distance (no more than 1m is recommended) using a cable.

It is allowed to switch firmwares with the engine running.

Also, you can see the video instruction: https://youtu.be/CiyAftnVTD0

Status indicator
On the CobraRTP v3.0 board of all variants, LED indicators of the current state of the device are provided:

Status – emulator status indicator has 2 modes:

Battery life:
At the first power supply, the indicator lights up and is constantly lit during operation..
Tuning:
When the emulator is connected to the software, the indicator will go out,\ and it will only light up again during identification, read, write, and verification operations.

Settings In tuning software

Before running the emulator in eCtune, HTS, Crome, BRE or TurboEDIT, you must make sure that the current target software ID corresponds to the program you intend to use (see CobraRTP Utility):

COBRARTP-R7-USB-Port-Module-FIG 15

To change, you must select the appropriate software in the list and “Apply” (at a time).
Always download the latest software.

eCtune:

Download the prepared version on our website in the “Downloads” section.

Open the program (eCtune.EXE).
Go: Settings – Emulator Comm, and set the following settings:

Notes:
you must select the COM port number (see Connecting to a PC) for emulation (RTP)! Or set the “Auto-Scan” checkbox to automatically select the COM port number (not recommended).

Settings for Datalog

Crome:

Notes:

You must select the COM-port number (see Connecting to PC) for Datalog (do not confuse with the COM-port number for emulation!).
The protocol should choose QD2, or if you use Crome Gold – QD3, respectively.
This value affects the speed of Datalog.
The rest of the software settings are similar.

General remarks!

In the battery version of CobraRTP (up to R4.0 version) battery is designed to store the downloaded ROM in the device’s memory, and when it is removed (after about 30 seconds), the memory will lose data. This can also occur with a short circuit or a complete discharge of the element (less than 2V).
Always be careful when installing (connecting) the device to the ECU, improper connection can lead to damage to the device.
Use always high-quality and as short as possible USB cable for reliable system operation.
Avoid installing the circuit board together with metal objects, which can lead to short circuits or voltage supply to unprotected parts of the device. Otherwise, securely isolate the device from the environment.

Frequent issues and their solutions:

CobraRTP connection error in the software during the first connection (or when switching to another software)

Decision:

check if the software ID is selected correctly in CobraRTP Utility
check if the COM port number is selected correctly.
check if the device is connected in other software at the moment (COM port can be connected in only one software).
If the problem persists, check CobraRTP hardware in the CobraRTP Utility in the Service->“Test” option.

Datalog connection issue:

Decision:

Check if the datalog wires are connected correctly
Check if the COM port for the datalog is correctly selected (differs from the emulation COM port number).
If you have a version with bluetooth – make sure that the used datalog channel is selected in the settings (CobraRTP Utility) (see above)
If the problem persists, check the compatibility of your computer with the datalog. (Jumper j12 is removed, J1 is installed, is the base ROM loaded, etc.), and check CobraRTP hardware in the CobraRTP Utility in the Service->“Test” option.
