Nga tuhinga:
1. Ka nui, ko tenei putanga e tohu ana i te he o te laser. He iti te tohu o te mahi noa. A kia kumea atu me te kaiwhakamaori 4.7 - 10kω i runga i te poari whakahaere.
2.. Tuhinga o mua. Ka toia ake i roto i te waahanga me te 4.7 - 10kω te pehi. Ona whenua ko:
Iti (0 - 0.8v): Whakawhiti i runga (> 0.8, <2.0v): Kaore i riro
High (2.0v ~ vcc + 0.3v): Whakawhitiwhiti Whakawhitiwhiti: Kua monokia te Whakawhiti
3. Mod-def 0,1,2. Koinei nga titi whakamāramatanga kōwae. Me kumea mai ratau ki te kaiwhakamaori 4.7k - 10kω i te poari whakahaere. Ko te huringa totoka-i waenga i te 2.0v ~ vcc + 0.3v.
Mod-de def 0 kua whakatauhia e te waahanga hei tohu kei reira te kōwae
Mod-def 1 Ko te raina karaka o te atanga waea rangatū waea e rua mo te ID Serial
Mod-def 2 ko te raina raraunga o te rua waea waea waea waea mo te ID Serial
4. Ka nui, ka tohu tenei putanga ki te ngaro o te tohu (Los). He iti te tohu o te mahi noa.
5. RD +/-: Ko nga putanga rerekee tenei. Kei te hono ratou ki te 100ω nga raina rereke e tika ana kia mutu me te 100ω (rereketanga) i nga waahanga kaiwhakamahi. Ka mahia te hononga ac i roto i te waahanga, kaore e hiahiatia ana i runga i te poari whakahaere.
6. Td +/-: Ko enei nga whakaurunga whakawhiti rereke. He mahi a raatau, he raina rereke me te 100ω te whakamutu rereketanga i roto i te waahanga. Ka mahia te hononga ac i roto i te waahanga, kaore e hiahiatia ana i runga i te poari whakahaere.
