- The protocol adapter of the invention includes a special pass-through mode that allows users to continue utilizing yesterday's in-house software, while communicating with today's hardware. Older software packages such as RP1202 and RP1210 can still be employed. This feature allows users to replace aging hardware with an interface that can support existing software.

- The protocol adapter of the invention expands functionality and usage of the earlier protocol adapter and can be used with a half-slot ISA card or in a PC-104 card version.
- The protocol adapter of the invention employs LED's to indicate status of the device, which mode of operation, and whether the adapter is in communication. By way of explanation and not limitation, dual color LED's are used to indicate which program is being executed by the protocol adapter. The pass-through ability to emulate other protocol adapters is indicated by a dual color LED to indicate the pass-through is functioning to emulate other protocol adapters.

Alternating red/green indicates reflash (reprogramming) is in progress.
- The status of the LEDs indicate to the user the mode of operation for the device and which of the various protocols is currently active. The meaning of the LED indicator status will be described below.
- It should be noted that earlier protocol adapters support communications with “older” protocols, but earlier protocol adapters do not provide an indication to the user as to which mode is being used (normal or pass-through).
- Earlier protocol adapters used a single color LED that could only notify the user that there is RS232 bus activity between the device and the PC. The protocol adapter of the invention uses an LED in the same physical location, but a dual-color LED allows indication of which mode is being used. A red LED is used to indicate when power is applied to the unit.

- The protocol adapter provides rapid access to any supported network by allowing the user to easily switch between protocols. This rapid access affords the user with the ability to monitor and translate messages between different protocols at the same time.
- An ISA, half-card version and a PC-104 version of the protocol adapter provide most of the functionality as described herein except for two functions. The two functions not supported by the ISA half-card version and the PC-104 version of the protocol adapter are the pass-through mode of operation and the Dearborn Programmable Bridge (DPB) software compatibility.
- The protocol adapter of the invention includes reflashing that allows the protocol adapter to be updated with new firmware in the field. This is accomplished by U5, U1, U8 and U4, which are shown in the figures. U5 (micro) processes a command sent to the protocol adapter by the host. It then copies the reflash instructions set (loader program) into RAM (U1) and then transfers control to that program (loader). The loader program responds to the commands from the host which allows the host computer to then clear and reprogram the Flash (U4). Once the reprogramming is complete, control is passed back to the flash program.
- The protocol adapter of the invention has status lights that allow the operator to determine what program is being executed by a protocol adapter embedded micro. U5 and U10 will flash the LEDs on the I/O board in a predefined manner at power up to indicate what version of firmware is being executed.
- The protocol adapter of the invention has a pass-through feature (voltage translator)/smart mode that allows the protocol adapter to emulate older boxes. In this mode of operation, the U5 (micro) delivers data directly form the J1708 Transceiver (U11 of I/O board) to the RS232 transceiver (U7 of I/O board) and monitors the data to provide J1708 defined timing signals on any or all of the RS232 hardware handshake lines.
- The expanded protocol adapter can be used wirelessly to perform ECU fault code interrogation, communication with a remote network, vehicle maintenance status checks or trip performance data downloads, and improved asset control, logistics and inventory management, diagnostic support, and maintenance/scheduling.
- An ISA version of the protocol adapter of the invention is a half slot card that supports CAN (J1939 and DeviceNet), SAE J1850, and GM UART protocols.
- The protocol adapter has additional unique features including bank switching, file upgrade capability, LED status, multiple datalinks, embedded versions, programmable manufacture's name, software locks, asynchronous transmit and receive, programmable timer, and a scratch pad.
- For bank switching, memory is swapped in and out of the processor's memory map to allow multiple programs to be run. For field upgrade capability, non-volatile memory can be programmed in the field to allow new software features to be added in the field. For LED status, LEDs are flashed in a unique sequence at power-up to indicated what version of firmware is being executed. Multiple data links may be supported at the same time. Firmware and hardware version numbers are available to the host to allow the host to determine current capabilities. The manufacturer's name is embedded in FLASH to allow VAR's to put in the name of the VAR's company.
- Proprietary software lock/key may be burned into FLASH to allow use of the VAR's software. The protocol adapter is capable of receiving and transmitting asynchronously of host processor and can broadcast on transmit and filter on receive.
- The protocol adapter has a programmable multi-function timer to support datalink communications. The scratch pad is a built-in remote access memory to allow the host to consolidate message data.
- Features of the protocol adapter of the invention are supported for RP1202 and RP1210, J1708 and J1939, and J1939 transport Layer. The protocol adapter has a Real Time Clock, Standard COMM port connection, 7-32 Volt Supply and is CE compliant.
- Now turning to the drawings, the circuits of the protocol adapter of the invention are shown in
FIGS. 1 through 20 . - The pass through/smart mode is U11 (shown on
FIG. 8 ) and is controlled by U5 (shown onFIG. 3 ) to determine if the host PC is listening to the J1708 link, or if the host PC is wanting to have a slave session with the DPA (diagnostic tool). - The U5 micro (
FIG. 3 ) at power up will flashLEDs FIG. 26 ) to allow the operator to know what version of software is running inside the protocol adapter or diagnostic tool (DPA). - Now turning to
FIGS. 21 through 25 , the LED descriptions are thereshown with the LED diagram shown inFIG. 26 . - In reference to
FIGS. 27-29 , the protocol adapter for transferring diagnostic signals is generally shown at 10. Theprotocol adapter 10 transfers the diagnostic signals between avehicle network 12 and ahost computer 14. A vehicle connector assembly generally indicated at 16 is interfaced with thevehicle network 12. Thevehicle connector assembly 16 includes avehicle connector 18 that is interfaced with thevehicle network 12. Thevehicle connector assembly 16 also includes acommon connector plate 20 that is interfaced with thevehicle connector 18. Thus, thevehicle connector assembly 16 mates or connects aspecific vehicle connector 18 with thecommon connector plate 20. A common electronics package generally indicated at 22 is interfaced with thecommon connector plate 20, and thecommon electronics package 22 wirelessly transmits the diagnostic signals from thevehicle network 12 to thehost computer 14. Typically, thecommon electronics package 22 has a plurality ofpads 23 which connect to the common connector plate in order for thecommon connector plate 20 to communicate with thecommon electronics package 22. - As stated above, the
protocol adapter 10 is capable of monitoring and translating multiple protocols that are used in thevehicle network 12. Thus, thecommon electronics package 22 determines a protocol of thevehicle network 12 that is being used. By way of explanation and not limitation, thecommon electronics package 22 determines the protocol by using a control logic which identifies the protocol or based upon the type ofvehicle connector 18 that is being used since specific types ofvehicle connectors 18 are typically used with a limited number of protocols. Additionally, thecommon electronics package 22 receives multiple protocols from thevehicle network 12 simultaneously. Further, theprotocol adapter 10 is capable of monitoring and translating multiple protocols from thevehicle network 12 simultaneously. - The
common connector plate 20 typically includes a plurality of pins which are accepted by thevehicle connector 18. Thus, when thecommon electronics package 22 determines what type ofvehicle network 12 it is interfaced with and the type ofvehicle connector 18 that is being used, thecommon electronics package 22 commands thecommon connector plate 20 to interface with thevehicle connector 18 using selected pins from the plurality of pins of thecommon connector plate 20. - The
common electronics package 22 transmits the diagnostic signals to thehost computer 14 using a selected wireless protocol. Typically, thecommon electronics package 22 is capable of transmitting signals in a plurality of wireless protocols, but a single wireless protocol is selected for transmitting the diagnostic signal based upon, among other things, thehost computer 14 and the type of signal desired by the user. Thus, thehost computer 14 can directly receive the wireless signal from thecommon electronics package 22 or can include a separate receiver that is interfaced with thehost computer 14 by, but not limited to, a serial port, a USB port, or the like. By way of explanation and not limitation, the wireless protocol can be IEEE 802.15.1, Bluetooth, IEEE 802.15.4, Zigbee, IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, or the like. - Alternatively, the

By having thecommon electronics package 22 enclosed in thehousing 24, thecommon electronics package 22 can be permanently connected to thevehicle network 12 and does not have to be connected and disconnected between uses. Thecommon electronics package 22 can also includeLEDs 26 for indicating the operation mode of thecommon electronics package 22. By way of explanation and not limitation, the LEDs can be used to show that the common electronics package is powered, the type of wireless signal that is being transmitted, and the speed of thecommon electronics package 22 is operating. As stated above, the LEDs can be bi-colored to show different operation modes of theprotocol adapter 10. - The
common electronics package 22 can also include areset switch 28. By way of explanation and not limitation, thereset switch 28 is a coin-switch which has two metal conductors. Thus, by sliding an electrically conducting object, such as but not limited to, a coin or the like, through a slot and connecting the two metal conductors, shorts the two contacts and closes the switch. By closing thereset switch 28, thecommon electronics package 22 is reset. By having such areset switch 28, thehousing 24 continues to be sealed while thecommon electronics package 22 can be reset. - By way of explanation and not limitation, the
vehicle connector 18 is a 9-Pin Deutsch, 6-Pin Deutsch, 4-Pin Haldex, 6-Pin General Motors Universal Asynchronous Receiver Transmitter (“GMUART”), Assembly Line Diagnostic Link (“ALDL”), or the like. By way of explanation and not limitation, thecommon electronics package 22 supports a plurality of protocols, such as Allision Transmission Electronic Control (“ATEC”), GMUART, Haldex Traction Systems (“HALDEX”), made by Haldex Traction AB Box 505, SE-261 Landskrona, Sweden, J1708, J1939, SAEJ1850 GM Class 2, SAE J1850 Chrysler,GM Class 1 UART (ALDL), ISO 9141-2, ISO 9141-1989, ISO 9141-Special protocol, SAE J2284, Dual Wire CAN protocol, SAE J2411, Single Wire CAN protocol, or the like. - It is beneficial to have a protocol adapter with a
common electronics package 22 andcommon connector plate 20 because there is only a single product that supports all vehicle networks 12. Thus, this reduces the manufacturing costs of the number of spare parts that must be stocked. For example, since thecommon electronics package 22 is separate from thevehicle connector assembly 16, a lesser number ofcommon electronics packages 22 needs to be stocked when compared to thevehicle connector assembly 16 which vary depending upon the vehicle. - The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
