Using the Outputs with RS-644 LVDS
You cannot directly use the RS-422 signal from a camera output line as an input to an RS-644 low
voltage differential signal (LVDS) receiver. However, if a resistor network is placed on the camera’s
output as shown in Fig. 21, you can use the signal from the camera’s output line as an input to an
RS-644 device.
For the camera’s I/O circuitry to operate properly, you must supply a ground as shown in Fig. 21.
Fig. 21: RS-422 Output Signal Modified for Use with an RS-644 Input
Although the RS-644 standard allows several devices to be connected together in
a "multidrop" configuration, we strongly recommend that you do not include any
camera output in an RS-644 multidrop. Instead, we strongly recommend that you
use a direct, point-to-point connection between the camera and your RS-644
LVDS receiver as shown Fig. 21.
