Detector System Component Description
41
Power
The power receptacle utilizes a 16-pin circular Lemo connector to provide the required
DC input power to the detector head and interfaces to the power supply unit via the
detection system’s power cable (JY# 400735).
USB 2.0
The USB 2.0 port accepts the standard USB-B end of the USB communications cable,
allowing true USB 2.0 “plug-n-play” communications between the Synapse and the
operating computer.
Shutter
The shutter drive interface is a BNC receptacle that accepts the shutter cable, connecting
the detector to the spectrograph shutter. This interface is intended to drive a single
electro-mechanical shutter having the following characteristics:
Coil
resistance: 12
ohms
Pulsed voltage to open:
+60 V DC
Hold voltage:
+5 V DC
Operating
frequency:
40 Hz maximum rep rate
TTL
Input/Output
Two TTL level Input/Output signals are available for monitoring and/or control of
various user accessories via SMB connectors located on the rear of the detector. To avoid
connection errors, a male gender SMB is utilized for the TTL input signal associated with
the External Trigger Input function, while its female gender counterpart provides for the
detection system’s TTL output signal capability. It should be noted that that the digital
logic associated with Synapse’s TTL output connector provides a multiplexed pathway,
making three signals available to the end-user (selectable via SynerJY software). A brief
description of the functionality associated with each TTL interface follows:
TTL Input (Trigger Input)
The TTL Input connector provides for the Trigger In function. Selection of the “External
Trigger” mode of operation enables Synapse to synchronize data acquisition to external
events. This input provides for either positive or negative edge triggering and is selected
by the user via software.
TTL Output (3 options programmable under SynerJY):
SHUTTER
The digital SHUTTER signal provides status with respect to shutter operation and is
activated during the interval when the CCD is being exposed to light.
START
EXPERIMENT
The START EXPERIMENT signal indicates the start of an experiment. Upon receipt of a
“Start Acquisition” command, this output goes to its active state after completion of its
