6 Timer 1 and Timer 2 Binary

Commands

The Timer 1 and Timer 2 parameters are used to set several aspects of exposure timing on A202k

cameras. On A202k High Gain cameras, the usage of the binary commands for setting Timer 1

and Timer 2 has changed.

On standard A202k cameras, when you use the Timer 1 binary command to set the value of Timer

1, the setting represents a value in microseconds. For example, if Timer 1 is set to a value of 10,

this represents 10 µs. The same is true for Timer 2 on a standard camera.

On A202k High Gain cameras, the setting for Timer 1 represents a multiple of 0.88889 µs. For

example, if you use the Timer 1 binary command to set the value of Timer 1 to 10, the setting

would represent a value of 10 x 0.88889 µs or 8.8889 µs. The same is true for Timer 2 on a high

gain camera.

Sections 6.1 and 6.2 show the details of the Timer 1 and Timer 2 commands on A202k High Gain

cameras.

6.1 Timer 1 Binary Command

Purpose: To set Timer 1 or to read the current Timer 1 setting. Timer 1 is used when the camera is

operating in ExSync programmable mode or in free-run mode. See Section 3.2 for details.

Type: This is a read or write command.

Read Command: Cmd-ID R/W-Flag Data Length Data

0xA6 1 3 -

Response: Cmd-ID R/W-Flag Data Length Data

0xA6 0 3 3 Bytes

Write Command: Cmd-ID R/W-Flag Data Length Data

0xA6 0 3 3 Bytes

Response: None

Data Format: Byte 1 Low byte of the Timer 1 setting

Byte 2 Mid byte of the Timer 1 setting

Byte 3 High byte of the Timer 1 setting

Data Range: Timer 1 setting can range from 13 (0x00000D) to 16777215 (0xFFFFFF).

The Timer 1 setting represents a multiple of 0.88889 µs. For example, if the

Timer 1 setting is 100, then the value of Timer 1 would be:

100 x 0.88889 µs = 88.889 µs
