USB 2.0 ki te RS422 RS485 Waea Whakaurutau
Whakaahuatanga Hua
Ko te DT-5019 he kaitahuri mo te USB 2.0 ki te RS485/RS422, kaore he taapiri hiko, he hototahi ki nga paerewa USB, RS422, RS485.Ka taea e ia te huri i nga tohu USB ki te tohu rereke rereke RS422, RS485 ranei.Kei ia raina te whakamarumaru ngaru, me nga momo whakamarumaru ngaohiko ngaohiko.Ko te iti o te tawhiti o te punga e whakamana ana i te atanga RS422 / RS485 o te tuku tere tere.RS422, RS485 hono ma te RJ45 me te atanga DB9.
Kaitahuri me te kore whakaroa te whakawhiti aunoa i roto, te arahiko I/O ahurei ka whakahaere aunoa i te ahunga rerenga raraunga, kaore he tohu ruru (penei i te RTS, DTR, me etahi atu) me nga huinga peke ka mohio ki te huri-rua, haurua-rua te huringa aratau, mono me te purei. .Whakaritea te whakatikanga o nga hua mo nga rorohiko whakawhitiwhiti korero me te atanga taputapu.
DT-5019 kaitahuri mo te tohu-ki-ira, te tohu-ki-maha nga korero pono.Ka whakarato i te tohu ki te nui ake o ia kaitahuri ka taea te hono atu i nga taputapu 32 RS422, RS485 ranei, te tere raraunga o te 300 ki te 921600bps.Ko te rama tohu hiko me te rerenga raraunga ka whakaatu he he mena ka pakaru.Ko te tautoko o te whakawhitiwhiti korero he USB ki RS422, USB ki RS485.
Ngā āhuatanga
1. Ira-ki-ira / 4-raina-taarua-katoa.
2. Ira-ki-maha-ira / 4-raina-taarua-katoa.
3. Ira-ki-ira / 2-raina haurua-rua.
4. Ira-ki-maha-ira / 2-raina haurua-rua.
I te wa e mahi ana te kaitahuri ki te taapiri-katoa, ki te haurua-rua ranei, me taapiri he parenga rite ki te karo i nga whakaata me te raruraru o te tohu.( 120Ω, 1/4W).
