2.7 Input Signals
The camera’s input signals include a SerTC signal and an ExSync signal as described below.
2.7.1 Serial to Camera
The Serial To Camera (SerTC) input signal is an RS-644 LVDS signal as specified in the Camera
Link standard. The signal is input to the camera on pins 7 and 20 of MDR connector one as specified
in the standard and as shown in Table 5 on
page 25 and in Figure 14 on page 32 .
Signals applied to the SerTC input are used to configure the camera. For more detailed information
about the serial connection, see Section 2.9 on
page 37 and Section 7.3 on page 196 .
2.7.2 External Sync (ExSync)
An external sync (ExSync) signal can be input into the camera and can be used to control line
acquisition and exposure time. The ExSync signal is an RS-644 LVDS signal as specified in the
Camera Link standard and is usually supplied to the camera by your frame grabber. The signal is
input to the camera on pins 9 and 22 of MDR connector one as shown in Table 5 on
page 25 and
in Figure 14 on page 32 .
When the camera is operating under the control of an ExSync signal, three exposure time control
modes are available: edge controlled, level controlled, and programmable. For more detailed
information about exposure control modes, see Section 4.1 on
page 67 .
When the camera is operating under the control of an ExSync signal, the period of the ExSync
signal determines the camera’s line rate:
Note that the ExSync signal is edge sensitive and therefore must toggle.
In order for the camera to detect a transition from low to high, the ExSync signal must be held high
for at least 1.3 µs when the camera is set for the level controlled exposure mode and for 100 ns
when the camera is set for programmable or edge controlled exposure mode.
