PORT #

Specifications

PIN #

T0 Output: LVCMOS FPGA output with limited ESD

protection, goes high at T0. Indicates a trigger has been

received.

Pre-Trigger Input: LVCMOS ESD-protected input. Pre-

Trigger is an optional signal that may be used to terminate the

continuous cleans instruction operation. In ordinary operation

there is a one clean cycle jitter between the trigger and the

finish of cleaning (i.e., the clean cycle in process must be

completed). A rising edge will cause a pre-trigger.

Note: The camera must already be in Acquire mode before the

pre-trigger is sent to the input.

GND: System chassis ground. Any external circuitry intended

to interface with the trigger control signals must reference this

ground connection.

Lockout Output: LOW indicates I.I.T. is locked off.

(NOT USED)

GND: System chassis ground. Any external circuitry intended

to interface with the trigger control signals must reference this

ground connection.

SyncMASTER1 Output: LVCMOS Active high. User-

configurable output. SyncMASTER1 can be user-configured to

provide a user-specified continuous frequency output (not just

when the camera is taking data) until halted by the user. In this

configuration, the output could be used to synchronize a laser,

shutter, AOTF... with the camera.

General Purpose Input 0: Reserved for future use as general

LVCMOS input limited ESD protection.

L_Shutter (via 1kOhm): Do Not Use.

Source Comp: Future Use. Analog Input.

Logic GND: Do Not Use.
