Configuration Aspects for Programmers
CSN14/TC/P Configuring Thermocouple Channels
Begin configuring input channels by first specifying the channel type. When the CSN14/TC/P signal
conditioning module is used, 16 differential thermocouple inputs are provided. In configuring thermocouple
(T/C) channels, all that is required is to assign each channel to a particular T/C type. Support for B, E, J, K, R,
S, T and N (14 and 28 gauge) thermocouple types are standard. The 100 mV, ±1 V, ±5 V, ±10 V, volts types
with and without range-error detection are also supported. Channel type can be defined using the Configure
Channel (
) command for a single channel or a range of channels. Channels not included in the channel scan do
C
not have to be configured. The following table highlights channel types for normal use of the CSN14/TC/P
signal conditioning card.
The
parameter is what distinguishes the channel as a thermocouple channel. The channel configuration
type
cannot be changed while the trigger is armed or an acquisition is taking place.
In addition to channel type, each channel in the scan channel can optionally have a high and low alarm level and
hysteresis associated with it. NetScan alarms allow the unit to produce an internal event when the value of a
channel is outside of desired limits. These alarm events can be used as trigger or stop events, or as a stimulus
for TTL-level signals on NetScan back panel.
The following example demonstrates how to assign a J type thermocouple to channels on a CSN14/TC/P signal
conditioning module plugged into NetScan.

CSN14/LV/ (T, B, or S) Configuring Low Volts Channels
When the CSN14/LV/ (T, B, or S) signal conditioning module is used, NetScan measures voltages providing a
programmable range per channel. To configure the channels on a CSN14/LV/ (T, B, or S), use the Configure
Channel (
) command to assign a range to each channel on the signal conditioning module. Channels not
C
included in the channel scan do not have to be configured.
The following table highlights channel types for the CSN14/LV/ (T, B, and S) signal conditioning card.
