5-4 Checking the Lens Resetting
<Generals>
(1) Setting the address according to the table below allows to check whether the lens resetting is ended or not.
(2) The 1st digit of binary number indication (Fig. 3-3 9 ) of data is for zoom, and the 2nd for focus resetting. Resetting is ended if 1
is indicated.
5-5 Functional Check of Control Keys and Switches
<Generals>
(1) In the service mode, the terminals of the MAIN and SUB microcomputer can be checked. Thereby, it is allowed to check key-
related operations and key-microcomputer connections in the product state.
(2) The addresses of the microcomputer terminals for checking are indicated in the “Remarks” column in the I/O port table (p. 2-14 to
p. 2-21). Note that since serial communication data signals are not synchronous with the LANC communication cycle (field) in the
service mode, operations related to these signals are not indicated accurately. So, use indications for these signals just as reference
data.
(3) The following explanations are provided for the data content which seem rather complicated. For other than below, use the
addresses shown in the “Remarks” column of the I/O port table.
(4) When carrying out functional checks, select the RD mode.
5-5-1 Voltage Range for A/D Input Key
(1) On the MAIN and SUB microcomputers, the terminals shown in Fig. 3-8 are A/D input ports. Key and/or mode is detected by
means of the A/D-converted voltage.
