Kev sib txuas lus USB
The Spartan 3 comes with a USB converter for communication with a computer. The USB converter uses the FTDI chipset, which is typically preinstalled on most operating systems.

Windows 10 Serial Terminal Teeb
To communicate with the Spartan 3 via serial commands on Windows 10:

1. Ensure Electronics Ground (Black), Heater Ground (White), and Power (Red) are connected and the Spartan 3 is powered.
2. Download tau thiab nruab Termite software los ntawm https://www.compuphase.com/software_termite.htm.
3. In the Windows search bar, type “Device Manager” and open it.
4. Locate the Spartan 3 USB converter listed as “USB Serial Port” (e.g., COM3).
5. In Termite, click on Settings, verify the Port is correct (e.g., COM3) and set the Baud rate to 9600.

Serial Commands

Nkag mus rau serial commands:

• Connect Electronics Ground (Black), Heater Ground (White), and Power (Red).
• Use commands like GETHW, GETFW, SETTYPE, etc., followed by specific values as per the usage note below.

Daim ntawv siv
Xa mus rau qhov muab examples to understand how to format and use the serial commands effectively based on the desired settings.

Ceeb toom

• Tsis txhob txuas lossis txiav lub Lambda Sensor thaum lub zog Spartan 3.
• Lub Lambda Sensor yuav kub heev thaum lub sijhawm ua haujlwm ib txwm, thov ceev faj thaum tuav nws.
• Tsis txhob nruab Lambda Sensor nyob rau hauv xws li ib tug yam ntxwv uas lub tsev yog powered ua ntej koj lub cav khiav. Lub cav pib tuaj yeem txav cov condensation nyob rau hauv koj lub tso pa tawm mus rau lub sensor, yog tias lub sensor twb tau rhuab, qhov no tuaj yeem ua rau thermal shock thiab ua rau cov ceramics hauv lub sensor tawg thiab deform.
• Thaum lub Lambda Sensor nyob rau hauv lub active tso kwj, nws yuav tsum tau tswj los ntawm Spartan 3. Carbon los ntawm ib tug nquag tso pa yuav yooj yim tsim nyob rau hauv ib tug unpowered sensor thiab foul nws.
• Lambda sensor lub neej thaum siv nrog cov roj lead yog nyob nruab nrab ntawm 100-500 teev.

Ntim Cov Ntsiab Lus

1 x Spartan 3 v2, 1 x USB Converter, 1 x Waterproof hniav fuse yas dhos, 2 x 5 Amp hniav fuse

Tso Txhim Kho

Lub Lambda sensor yuav tsum tau nruab nruab nrab ntawm 10 teev thiab 2 teev tsaus ntuj txoj hauj lwm, tsawg dua 60 degrees los ntawm ntsug, qhov no yuav tso cai rau lub ntiajteb txawj nqus tshem tawm cov dej condensation ntawm lub sensor.
Rau tag nrho Oxygen sensor installation, lub sensor yuav tsum tau ntsia ua ntej lub catalytic converter.

Rau ib txwm aspirated engine lub sensor yuav tsum tau ntsia li 2ft ntawm lub cav tso qhov chaw nres nkoj. Rau cov cav turbocharged lub sensor yuav tsum tau ntsia tom qab lub turbocharger. Rau cov tshuab supercharged lub sensor yuav tsum tau nruab 3ft ntawm lub cav tso qhov chaw nres nkoj.

Fuse

Sib 5 amp fuse rau hauv lub fuse tuav, txiav hlau ntawm nruab nrab, thiab ruaj ntseg hau. Ib qho kawg ntawm lub fuse tuav txuas mus rau Spartan 3 liab xaim rau lwm qhov kawg ntawm lub fuse tuav txuas mus rau qhov hloov pauv 12 [v] qhov chaw, roj twj tso kua mis relay feem ntau pom zoo.

CAN Bus Protocol Default Format (Lambda)

Rau %O2 CAN Format thov saib "Spartan 3 thiab Spartan 3 Lite rau Lean Burn thiab Oxygen Metering Applications.pdf" Spartan 3's CAN Bus ua haujlwm nrog 11 me ntsis chaw nyob.

• Default CAN Baud tus nqi yog 500kbit / s
• Default CAN Termination resistor yog qhib, qhov no tuaj yeem hloov pauv los ntawm kev xa "SETCANRx" serial command.
• Default CAN Id yog 1024, qhov no tuaj yeem hloov pauv los ntawm kev xa "SETCANIDx" serial command.
• Data Length (DLC) yog 4.
• Default Data Rate is 50 hz, data is sent every 20[ms], this can be changed by sending “SETCANDRx” serial command. Big-endian for all data
• Data[0] = Lambda x1000 High Byte
• Data[1] = Lambda x1000 Low Byte
• Data[2] = LSU_Temp/10

CAN Termination Resistor:
Piv txwv tias peb hu rau ECU; Master, thiab cov khoom siv uas xa / tau txais cov ntaub ntawv rau / los ntawm ECU peb hu; qhev (Spartan 3, digital dashboard, EGT maub los, thiab lwm yam ...). Hauv cov ntawv thov feem ntau muaj ib tus Xib Hwb (ECU) thiab ib lossis ntau tus qhev uas txhua tus sib koom tib lub tsheb npav. Yog tias Spartan 3 yog tib tug qhev ntawm CAN Bus ces CAN Termination Resistor ntawm Spartan 3 yuav tsum-tau qhib siv cov lus txib "SETCANR1". Los ntawm lub neej ntawd CAN Termination Resistor ntawm Spartan 3 tau qhib. Yog tias muaj ntau tus qhev, tus qhev uas nyob deb tshaj ntawm tus Xib Hwb (raws li qhov ntev ntawm txoj hlua) yuav tsum muaj CAN Termination Resistor enabled, tag nrho lwm cov qhev yuav tsum muaj lawv CAN Termination Resistor
disabled/disconnected. Hauv kev xyaum; Nws feem ntau tsis muaj teeb meem yog tias CAN Termination Resistors raug teeb tsa kom raug, tab sis rau kev ntseeg siab tshaj plaws CAN Termination Resistors yuav tsum tau teeb tsa kom raug.

Bootloader
Thaum Spartan 3 powered tsis muaj LSU Heater Ground, dawb xaim, txuas nws yuav nkag mus rau bootloader hom. Fais fab mus rau Spartan 3 nrog lub rhaub hauv av txuas nrog yuav tsis ua rau lub bootloader thiab Spartan 3 yuav ua haujlwm li qub.

Warranty

14Point7 lav Spartan 3 kom tsis txhob muaj qhov tsis xws luag rau 2 xyoos.

Tsis lees paub
14Point7 yog lav rau kev puas tsuaj tsuas yog mus txog tus nqi yuav khoom ntawm nws cov khoom. 14Point7 cov khoom yuav tsum tsis txhob siv rau hauv txoj kev pej xeem.

FAQ

Dab tsi yog suav nrog hauv pob Spartan 3 v2?
