Scan Channel

Configuration

Register

These bits set the <channel_list> for a scan list, set the type of measurement and enable/disable the tree isolation switches. Note that the DIR in the Status/Control Register must be set false to enable this register.

Read								Undefined

D3 - D0 These bits set the channel number, with a range of 0 - 15. Bit D0 is the least significant bit, and bit D3 is the most significant.

Configuration Bit These bits determine the measurement mode as listed below:

(C1 - C0)

C1	C0
0	0	Volts
0	1	2-wire ohms
1	1	4-wire ohms
1	0	Thermistor

B and A Tree Isolation

Switch Disable

(B-D, A-D)

Valid Channel (VLD*)

Note that to obtain the Thermistor reference temperature for Thermocouple measurements, you must set the configuration bits for Thermistor. After you have obtained the reference temperature, set the bits for Volts.

A zero in either one disables the respective Tree Isolation Switch. Generally, both disabled together equal the [ROUTe:]SCAN:PORT NONE command.

A zero indicates that the specified channel is valid. When entering a scan list the entire list must be loaded into each module. For the channels that are not on that module, the VLD* must be set false. See [ROUTe:]SCAN in the “ Executing Commands” section in this Appendix.

Direct Channel

Configuration

Register

The Direct Channel Register allows you to specify channels to be closed individually. Note that the DIR bit in the Status/Control Register must be set true for this register to be enabled.

base + 0C16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0

Read								Undefined

D3 - D0 These data bits set the channel number with a range of 0 - 15. Bit D0 is the least significant bit, and bit D3 is the most significant.
