CIO-EXP16 User's Guide Installing the CIO-EXP16
Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections (available at www.mccdaq.com/signals/signals.pdf ).
Configuring the CIO-EXP16
Before using the CIO-EXP16, there are switches and jumpers to set, and one or more cables to install. Please
turn the PC power OFF before proceeding. The CIO-EXP16 is shipped with the factory-default settings listed in
the following table.
Factory-configured default settings
Jumper/switch Description Default setting
Power source select switch
S3
+5V power switch that sets the power source to
internal or external
INT (in5V PC power)
A/D BOARD TYPE jumper Selects DAS08 or DAS16 compatibility DAS08
EXP OUTPUT TO DAS
jumper Selects the A/D board channel to connect the
multiplexed analog output to. 0
(EXP multiplexed output connects to
channel 0 on the A/D board)
CJC OUTPUT TO DAS
jumper Selects the A/D board channel to connect the
CJC output to. 7
(CJC circuit connects to channel 7 on
the A/D board)
GAIN switches
S1 Four DIP switches that set the gain of the
differential amplifier. Gain = 1 (all gain switches OFF)
V, C and G solder bridge
switches (one for each input
channel) Three 'connect pads' per channel on the etch
side (under side) of the CIO-EXP16 board.
Bridge each pad to configures its associated
input channel as follows:
ƒ
Bridge the
V
pads to enable open
thermocouple detection for the associated
input channel.
ƒ
Bridge the C pads to connect a 1 µF
capacitor across the signal high and low
inputs, forming a low-pass filter having a 7
Hz cutoff.
ƒ
Bridge the G pads to enable a reference to
ground for the associated input channel.
Open pads (all are not bridged)
