Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1

Mwachidule  

Mawonekedwe a G.703 (Co-Directional G.703) amagawaniza kuzungulira kwa 64Kbps mu magawo anayi a mayunitsi, amagwiritsa ntchito "0101" kuyimira "0", "1100" kuyimira "1". Mwa kusintha kusintha kwa polarity ya block yoyandikana, ma signature a binary amasintha ma sign atatu. Pagulu lililonse lachisanu ndi chitatu linawononga chipika cha polarity alternating, motero kufalitsa chizindikiro cha 8KHz. Potengera zomwe zili pamwambapa, chizindikiro cha G.703 chogwirizana ndi 64Kbps chitha kutumiza chizindikiro chanthawi ya 64KHz ndi 8KHz ndi 64KHz ndi chizindikiro cha data cha 64Kbit/s mbali imodzi yokhala ndi mzere wokhazikika.
64k-RS232/422 / 485 mawonekedwe Converter amapereka ITU-T co-64K G.703 muyezo E1 mawonekedwe ndi muyezo RS232 / 422/485 kutembenuka mawonekedwe pakati wosanjikiza thupi. Network kuti apereke kulumikizana kotetezeka pakati pa zida zamitundu yosiyanasiyana, kulumikizana kopanda msoko. Zoyenera zida zotumizira E1 mipata yagawo yomwe ilipo, ndi zida zofunika kusamutsa deta ndi ma RS232/422/485 okha.

Chithunzi cha malonda

Mtundu wa Mini

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Perekani mitundu ya wotchi ya 2: Co-Directional G.703 master clock ndi G.703 line clock;
• Perekani ntchito ziwiri za loopback, zomwe ndi G.703 za kuzungulira kwanuko, RS232 / 422/485 kuchokera ku lupu lapafupi.
• Pseudo-random code test ntchito, imabweretsa mwayi waukulu pakuyika ndi kutumiza zida
• Ma co-directional 64K G.703 amathandizira 120Ω kusakhazikika bwino;
• AC 220V, DC -48V, DC + 24V mphamvu Optional, DC magetsi palibe mfundo zabwino ndi zoipa;
