TRIGGER
Flashes when ARMed (waiting for a trigger), is ON continuous when triggered; is OFF when
data collection is finished. Trigger is also turned OFF by IEEE DCL or SDC.
SCAN
ON when NetScan is storing a channel scan in its internal buffer.
SEND
ON when transmitting data to the serial interface (for RS-232 operation only).
RECEIVE
ON when receiving data from the controlling computer (for RS-232 operation only).
ERROR
ON when an error has occurred, OFF when no error condition exists. See the Error Query (E?)
command for more information.
POWER

Description
Power
Connector
Provides a means for connecting NetScan to one of two voltage supplies:
105 - 125V, or 210 - 250V. The connected power supply must agree with that selected by
NetScan’s internal slide switch (described later in this chapter).
Power Switch
Turns power ON or OFF.
Chassis Ground
A single point grounding node for, but not limited to, thermocouple shield termination.
Calibration
Enable/Disable
Pushbutton used to enable/disable the hardware protected portion of NVRAM during NetScan
main unit calibration. Refer to Chapter 6 for detailed information.
Trigger In
BNC Trigger input for initiating and/or stopping acquisition with TTL input signal
TTL Output
BNC TTL Scan output signal occurs for each channel scan; used for synchronizing other
equipment with NetScan acquisition.
Alarms & Digital I/O
(DB50) Connector
DB50 connector offers easy access to Alarms and Digital I/O (32 digital outputs and 8 digital
inputs)
RS-232/422 (DB9)
Connector
Serial port for operation at remote distances from controlling computer supports 300 to 9,600
baud using RTS/CTS or XON/XOFF handshaking.
DIP Switch
Used for selecting RS-232 or RS-422 and respective communication parameters, i.e.,
handshaking, parity and Baud Rate.
Interface Card Slot
For installing the optional IEEE 488 interface card. Note that RS-232 serial interface is the
default and is possible with or without an interface card.
