Outputs

Output features are configured by software. Any signal can be placed on any

output.

The main features of output signals are described below:

Note



• Switching trigger delay to ON also switches external

Trigger_Mode_0 to ON.

• This feature works with external Trigger_Mode_0 only.

Note



For a general description of the outputs and warnings see

the Hardware Installation Guide, Chapter Guppy PRO out-

put description.

Signal Description

IntEna (Integration Enable) signal This signal displays the time in which exposure was made. By

using a register this output can be delayed by up to 1.05 sec-

onds.

Fval (Frame valid) signal This feature signals readout from the sensor. This signal Fval

follows IntEna.

Busy signal This signal appears when:

• the exposure is being made or

• the sensor is being read out or

• data transmission is active.

The camera is busy.

PulseWidthMod (pulse-width modu-

lation) signal

Each output has pulse-width modulation (PWM) capabilities,

which can be used for motorized speed control or autofocus

control. See Chapter Pulse-width modulation on page 85ff.

WaitingForTrigger signal This signal is available and useful for the outputs in Trigger

Edge Mode. (In level mode it is available but useless, because

exposure time is unknown. (Signal always =0))

In edge mode it is useful to know if the camera can accept a

new trigger (without overtriggering).
