Input transistor chuahmi thlennak A dang tein chiahmi himnak dawnkhantu hna nih a dang tein a ummi himnak khamnak hna hmangin ttihnung hmun ah thlennak pehtlaihnak asiloah naih tein thlennak hna in luhternak signal kha transistor chuahnak he a himmi hmun ah an kuat. Input nih cun a tthawngmi transistor chuahmi kha a uk. A chuakmi nih a fiantermi dirhmun pali a ngei: short-circuit ralrin peknak doh khawhnak ≤ 240 Ω, 1-signal 1.4KΩ ≤ doh khawhnak man ≤ 1.6KΩ, 0-signal 13KΩ ≤ doh khawhnak man ≤ 14KΩ, le a rawkmi ralrin peknak doh khawhnak > 1.6KΩ. Hi chuahmi sining nih hin signal line cung i line dirhmun kha a lehrulh. Module i dip switch pawl cu luhchuah le chuahnak kha lam khatlei ah asiloah a hnulei uknak ah chiah awk le line palhnak ralrin peknak riantuannak chiah awkah hman a si. Hi thilri nih hin a dang tein mei a herh, a dang tein mei a herh, luhternak le chuahnak terminal hna he.
