TM/ RM-1327GE Series
24 Serial Commands
Inputs I0 through I7 can be either external or internal inputs to the look-up table. The outputs are
used by the imager part of the GE camera.
The HD and VD signals can be passed through, bypassing the GPIO lookup table. Figure 24 on page 20
shows a screen dump of the GPIO configuration page, where HD/VD bypass selection can be made.
The default value 0 (zero) is through the lookup table. Value 1 (one) is bypassing the lookup table.
The SDK and the Cam2Net Camera Interface Application both supply methods to select GPIO bypass
of the external VD and HD (I1 and I2).
You can select which signal source to lead to the GPIO inputs. This is done in the GPIO look-up table
page as shown in Figure 23.

4.3 GPIO Label Tables
Table 2 shows which GPIO inputs carry the different signals. The top line for each label contains the
default signal.
