NOTE THESE REMOTE SHUTDOWN PROPERTIES
:
An open circuit applied to
the REMOTE SHUTDOWN input indicates a warm detector; therefore, the high
voltage is turned off. Drawing a current of
500 µA from the REMOTE SHUTDOWN
input indicates a cool detector; therefore, the high voltage can be turned on.
The REMOTE SHUTDOWN input is clamped at
700 mV by an internal clamp.
CHANGE SAMPLE
Rear-panel BNC provides TTL signal level to control an external device
such as a sample changer. CHANGE SAMPLE can be set for either TTL level via software
command.
SAMPLE READY
Rear-panel BNC accepts TTL signal level from an external device such as
a sample changer. SAMPLE READY can be set to read either TTL level via software control.
PREAMP POWER
Rear-panel, 9-pin D connector; provides ±24 V and ±12 V for
preamplifier power.
5.1.3. Controls
HIGH VOLTAGE BIAS
0–5 kV, rear-panel 10-turn precision potentiometer sets the value of
the bias voltage.
5.1.4. Interface Connectors
DUAL-PORT MEMORY
Interface bus, rear-panel, 37-pin D connector.
RS-232-C
Rear-panel standard RS-23-C, 9-pin D connector, male, wired as DTE to run at
19.2K baud maximum, with modem control.
ETHERNET
Rear-panel BNC connector accepts IEEE 802.3 10BASE2 (thin coax).
