2019 Kina Hoʻolālā Hou 16e1 i 4ethernet mea hoʻololi - Co-Directional 64K-RS232/422/485 mea hoʻololi JHA-CE1tD1/R1/Q1 – JHA

Hoʻololi Kūkākūkā 64K-RS232/422/485 JHA-CE1tD1/R1/Q1

Nānā nui  

Hoʻokaʻawale ka G.703 (Co-Directional G.703) i ka pōʻaiapuni 64Kbps i 4 mau kikowaena, hoʻohana ʻo ia i ka "0101" e hōʻike ana i ka "0", "1100" e hōʻike ana i ka "1". Ma ka hoʻololi ʻana i ka polarity o ka poloka pili, hoʻololi nā hōʻailona binary i nā hōʻailona pae ʻekolu. I kēlā me kēia hui 8 i luku ʻia ka poloka o ka polarity ʻokoʻa, no laila e hoʻouna i ka hōʻailona manawa 8KHz. Ma ka coding i luna, hiki i ka G.703 co-directional 64Kbps hōʻailona ke hoʻokō i ka hoʻouna ʻana i ka hōʻailona manawa o 64KHz a me 8KHz a me 64KHz a me ka hōʻailona ʻikepili o 64Kbit/s ma ka ʻaoʻao like me kahi laina kaulike pālua.
64k-RS232/422 / 485 mea hoʻololi hoʻololi i hāʻawi iā ITU-T co-64K G.703 maʻamau E1 interface a me RS232 / 422/485 maʻamau hoʻololi ma waena o ka papa kino. Pūnaewele e hāʻawi i nā kamaʻilio paʻa ma waena o nā polokalamu o nā ʻokoʻa like ʻole, ka pilina paʻa ʻole. He kūpono no ka hoʻouna ʻana i nā ʻāpana ʻāpana E1 i loaʻa, a me nā mea pono e hoʻololi i ka ʻikepili a me nā manawa puka RS232 / 422/485 wale nō.

Nā hiʻohiʻona

• Ma muli o ka IC pono'ī
• Hāʻawi i 2 ʻano uaki: Co-Directional G.703 master clock a me G.703 line clock;
• Hāʻawi i ʻelua hana loopback, ʻo ia hoʻi G.703 o ka loop local, RS232 / 422/485 mai ka loop local.
• Pseudo-random code test function, lawe mai i ka ʻoluʻolu nui i ka hoʻonohonoho ʻana a me ka hoʻokō ʻana i nā mea hana
• Kākoʻo ka co-directional 64K G.703 i ka 120Ω impedance kaulike;
• AC 220V, DC -48V, DC + 24V mana Koho, DC mana lako ʻaʻohe wahi maikaʻi a maikaʻi ʻole;
