Physical InterfaceBasler sprint Mono Cameras 332.7 Input SignalsThe camera’s input signals include a SerTC signal and an ExSync signal as described below.2.7.1 Serial to CameraThe Serial To Camera (SerTC) input signal is an RS-644 LVDS signal as specified in the CameraLink standard. The signal is input to the camera on pins 7 and 20 of MDR connector one as specifiedin 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 informationabout 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 lineacquisition and exposure time. The ExSync signal is an RS-644 LVDS signal as specified in theCamera Link standard and is usually supplied to the camera by your frame grabber. The signal isinput to the camera on pins 9 and 22 of MDR connector one as shown in Table 5 on page 25 andin Figure 14 on page 32.When the camera is operating under the control of an ExSync signal, three exposure time controlmodes are available: edge controlled, level controlled, and programmable. For more detailedinformation 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 ExSyncsignal 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 highfor at least 1.3 μs when the camera is set for the level controlled exposure mode and for 100 nswhen the camera is set for programmable or edge controlled exposure mode.Line Rate 1ExSync Signal Period---------------------------------------------------------=
