TempScan / MultiScan User's Manual Chapter 2: TempScan/1100 & MultiScan/1200 13
Rear Panel Switches & Connectors
Two (2) switches, seven (7) connectors, one (1) grounding nut, and one (1) input card slot on the rear
panel of either the TempScan/1100 or MultiScan/1200 provide power, IEEE 488 addressing,
triggering, a single point grounding node, and I/O connections.
• Power Switch: Used to turn power to the unit ON and OFF. When the switch is in the depressed
position the power is ON. When in the extended position, the power is OFF.
• DIP Switch: For IEEE 488: Used for selecting IEEE 488 communication and bus address. For
RS-232/RS-422: Used for selecting RS-232/RS-422 serial communication, handshaking, parity and
baud rate. Microswitch 9 is used to enable/disable the hardware protected portion of NV-RAM.
• Power Connector: Provides power for the unit. Internally configurable for either 105-125 or 210-
250 VAC, 50/60Hz, plus fuse circuit breaker.
• IEEE 488 Connector: Port for the IEEE 488 interface.
• RS-232C/RS-422 Connector: DB9 serial port for operation at remote distances from controlling
computer supports 300 to 9,600 baud using RTS/CTS or XON/XOFF handshaking (XON/XOFF
for ASCII transmissions only).
• TTL Output Connector: BNC TTL scan output signal occurs for each channel scan; used for
synchronizing other equipment with TempScan/1100 or MultiScan/1200 acquisition.
• Trigger Input Connector: BNC trigger input for starting and/or stopping acquisition of the TTL
output signal.
• Alarms & Digital I/O Connector: DB50 port offers easy access to Alarms and Digital I/O (32
digital outputs and 8 digital inputs)
• Master/Slave Connector: DB25 master/slave port connects to Exp/10A and/or Exp/11A expansion
slave units to support applications of up to 992 channels with the TempScan/1100 master unit, or
up to 744 channels with the MultiScan/1200 master unit.
• Grounding Screw: An external single-point grounding node has been supplied for (but not limited
to) thermocouple shield termination.
