Operating instructions
4 30H - 38H
bit0 (lsb) Auto Iris; 0 = auto, 1 = manual
bit1 Camera power; 0 = o, 1 = on
bit2 Lens speed; 0 = slow; 1 = fast
bit3 Comm. error; 0 = no, 1 = yes
bit4 - bit7 = 0011.
5 “A” Upper case “A”
6 30H - 31H bit0 (lsb) aux output; 0 = o, 1 = on
7
Terminator and
Checksum
80H - 8FH Most signicant nibble is always 8. Least signicant (LS) nibble is the XOR of all
previous bytes (LS nibble only) except for leading autobaud character F8H.
