3.5.2.1 Balancing Gain Settings When Using Binary Commands

The left side gain is set using the Left Side Gain binary command (see Section 4.2.4.10) and the
right side gain is set using the Right Side Gain binary command (see Section 4.2.4.12). Each gain
setting can be programmed on a decimal scale that ranges from 0 to 1023 (0x0000 to 0x03FF),
however, values lower than 288 (0x0120) should not be used.
The gain reference values can be read using the Read Reference Gain Values binary command
(see Section 4.2.5.9). The sample calculation below shows how to use the reference values.
Sample Calculation Using the Reference Values
Assume that you are working with an A202
want to keep the left side and the right side of the image in balance.
1. Read the reference values that were stored during the camera's calibration procedure using
the "Read Reference Gain Values" binary command (see Section 4.2.5.9). For our example,
we will assume that the camera returned the following reference values:
Byte 1 - Low byte left side reference gain after decimal point
Byte 2 - High byte left side reference gain after decimal point
Byte 3 - Low byte left side reference gain before decimal point
Byte 4 - High byte left side reference gain before decimal point
Byte 5 - Low byte right side reference gain after decimal point
Byte 6 - High byte right side reference gain after decimal point
Byte 7 - Low byte right side reference gain before decimal point
Byte 8 - High byte right side reference gain before decimal point
2. The reference values are hexadecimal. Convert them to decimal:
Byte 1 = 0
Byte 5 = 0
3. Use the decimal values of Byte 4 through Byte 1 to determine the reference gain for the left
side (RG
