4.6 – INPUT/OUTPUT SELECTION
Selections of input and output signal types are made on the Jumper section of the I/O board, see Figure 5.1. Remove
top cover to gain access to the Jumper board. Figure 4.6 depicts the Jumper board and the pins associated with
specific input and output signal types.
Figure 4.6
Table 4.1 lists the identifier for each row of pins to be jumpered for a specific input or output signal type.
Table 4.1
The necessary jumpers have been installed at the Factory for customer specified inputs and outputs (see Factory
Set-Up Information Sheet).
To change the signal type of an input or output, remove all jumpers from the present signal type pins and install them
on the desired signal type pins.
Inputs have a single jumper covering two pins, and outputs have two jumpers covering four pins.
4.7 – DISPLAY CONTRAST ADJUSTMENT
To compensate for different ambient lighting conditions and viewing angles, the CAMM display's contrast can be
adjusted for optimum visibility.
Contrast is adjusted using potentiometer R1 on CPU board (see Figure 5.1). To gain access to R1:
• Remove the two 10-32 screws on front cover and pull the cover straight and to the right.
• Turn R1 clockwise to increase contrast (darken characters relative to background) and counterclockwise to decrease
contrast.
