TempScan / MultiScan User's Manual

Two (2) switches, three (3) connectors, one (1) grounding nut, and ten (10) input card slots on the rear
panel of the Exp/11A provide power, slave addressing, master/slave connections, a single point grounding
node, and scanning card expansion.

Power Switch: Used to turn power to the Exp/11A 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: Used for selecting the Exp/11A slave address ID.
Power Connector: Provides power for the unit. Internally configurable for either 105-125 or 210-250

VAC, 50/60Hz, plus fuse circuit breaker.

Master/Slave Connector: Two DB25 master/slave ports provide one connection to a TempScan/1100,

MultiScan/1200, Exp/10A or Exp/11A unit, and one connection to another Exp/10A or Exp/11A
expansion unit.

Grounding Screw: An external single-point grounding node has been supplied for (but not limited to)

thermocouple shield termination.

Shielded Enclosure: For the TempScan/1100: Accepts any combination of TempTC/32B,

TempV/32B, and/or TempRTD/16B scanning cards. For the MultiScan/1200: Accepts any
combination of MTC/24 and/or MHV/24 scanning cards. Note that the TempScan/1100 and
MultiScan/1200 scanning cards must not be mixed within the same system.
