Command No. Command Descriptions
14H:
UART[7 0]
[Communication mode] Initial Data: 01H
This sets the communication modes.
D[7 0]
D7 D6 D5 D4 D3 D2 D1 D0
D7~D2: No Function Set always “000000”
D1~D0: Communication Mode 00: 38,400 bps 01: 9,600 bps
10 to 11: No function (Prohibited setting. Do not set these
values)
20H:
SVR[7 0]
21H:
SVR[15 8]
[Exposure time (H) of the electronic shutter]
Initial Data: SVR[15 0] = 0, Data Range: 0 to 4095
Sets the preset shutter speed (or CCD exposure time) for electronic shutter.
The preset shutter speed is defined by the following formula.
Exposure time (shutter speed) = SVR[15 0] x (1H cycle time) + SHR[15 0] x (1CLK cycle time)
Notes:
1. The camera works with the shutter off position (maximum frame exposure time) when both SVR and
SHR are set at “0”.
2. The camera works with the minimum shutter speed when this value is set to 0 and the value of SHR is
set between 1 and 600.
3. The value is replaced with 4095 automatically when the value set greater than 4095.
22H:
SHR[7 0]
23H:
SHR[15 8]
[Exposure time (CLK) of the electronic shutter]
Initial Data: SHR[15 0] = 0, Data Range: 0 to 1923
Sets the preset shutter speed (or CCD exposure time) for electronic shutter.
The previous section, the preset shutter speed is defined by the following formula:
Preset shutter speed = SVR[15 0] x (1H cycle time) + SHR[15 0] x (1CLK cycle time)
Notes:
1. The camera works with the shutter off position (maximum frame exposure time) when both SVR and
SHR are set at “0”.
2. The camera works with the minimum shutter speed when SVR is set to 0 and this value is set
between 1 and 600.
3. The value replaces by 1923 automatically when the value set greater than 1923.
24H:
PSR[7..0]
25H:
PSR[15 8]
[Start line of the variable partial scanning]
Initial Data: PSR[15 0] = 0, Data Range: 0 to 2057
This sets the start line number of the variable partial scanning area.
Actual start line of the partial scanning = this value + 1
Notes:
1. The value replaces by 2057 automatically when the value set greater than 2057.
2. The camera works with full scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 2058.
