Txheej txheem cej luam:
Hima F 8621 Ib tus coprocessor module nta nws tus kheej microprocessor, HD 64180, thiab ua haujlwm ntawm lub moos zaus ntawm 10 MHz. Nws feem ntau suav nrog cov haujlwm hauv qab no:
384 KByte zoo li qub nco, CMOS-RAM, thiab Eprom ntawm 2 ICS. Tus RAM yog roj teeb-buffered los ntawm lub hwj huam muab tshuaj xyuas module f 7131.
2 Rs 485 Interfaces (ib nrab-duplex), nrog cov galvanic rho tawm thiab nws tus kheej kev sib txuas lus processor. Tus nqi sib kis (teeb tsa ntawm software): 300, 600, 2400, 2400, 500, 500, 5,200, 500600BPS, lossis saib xyuas qhov tseem ceeb teem rau ntawm CU ntawm DIP Hloov.
Dual Port RAM rau kev nco nrawm rau lub chaw nruab nrab thib ob.
Qhov chaw yuav tsum tau: 4 Te.
Kev lag luam hluav taws xob: 5 V DC, kev siv tam sim no: 360 ma.
Cov yam ntxwv ntawm Hima F {0}} A:
- Processor: tus nws f 8621 ib tug coprocessor module yog nruab nrog HD 64180 ntawm lub moos zaus ntawm 10 MHz.
- Lub cim xeeb loj heev: kev suav ntawm 384 KB ntawm cov cim xeeb zoo li qub (CMOS-RAM thiab EPROM), khaws cia ceev ceev ntawm cov ntaub ntawv hauv kev ua haujlwm tiag tiag.
- Roj teeb-Buffered RAM: RAM yog roj teeb-Buffered los ntawm lub zog saib xyuas kev hloov kho (F 7131), kom ntseeg tau tias cov ntaub ntawv uas tau khaws cia txawm tias lub zog lossis kaw hluav taws xob.
- Dual RS 485 Interfaces: Tus Qauv Tshaj Tawm Ob RS 485 Interfaces (ib nrab-duplex) nrog cov galvanic kev rho tawm thiab nws tus kheej kev sib txuas lus processor.
- Cov chaw nres nkoj dual-Port rau cov cim xeeb ceev: Cov ntaub ntawv loj uas tso cai rau cov ntaub ntawv ceev ceev ntawm coprocessor ntawm coprocessor thiab lwm qhov chaw nruab nrab.
Chaw S1 ... S4 rau Rs 485 Interfaces:
Interface 1:
Interface 2:
Lwm qhov chaw raws li tau muab nyob rau hauv lub rooj tsis pom zoo.
Pin faib cov RS 485 interface raws:
| Rab koob | Rs 485 Kos Npe | Kev piav txog |
|---|---|---|
| 1 | - | Tsis siv |
| 2 | Kheej | 5 v, decoupled los ntawm diodes |
| 3 | A/A | Rxd / TXD-APE txais / xa cov ntaub ntawv-A |
| 4 | - | CNTR-ib tug tswj teeb liab a |
| 5 | C/C | Dgnd cov ntaub ntawv hauv av |
| 6 | Vp | 5 v, tus ncej ntawm lub zog fais fab |
| 7 | - | Tsis siv |
| 8 | B/B | Rxd / TXD-B tau txais / Kis-cov ntaub ntawv-B |
| 9 | - | CNTR-B tswj teeb liab B |
Qhov no yog cov haujlwm tseem ceeb ntawm lub Hima F {0}} ib tug coprocess module thiab tus lej PIN kev teeb tsa ntawm Rs 485 interface.
