Figure 14.0-3 T7 Analog Inputs
 |
The LabJack T7 has 14 built-in analog inputs, readable as AIN0-13:
- AIN0-AIN3 are available on the screw terminals and on the DB37 connector. See "Duplicated Terminals" below.
- AIN4-AIN13 are available only on the DB37 connector.

AIN#(0:13)_BINARY
Returns the 24-bit binary representation of the specified analog input. If you prefer 16-bit representation, simply divide this by 256. This is for command-response only. Stream always returns binary and LJM applies cal constants, so the LJM config flag LJM_STREAM_AIN_BINARY is used to get binary values.

In addition to the 14 built-in analog inputs, the T7 has special and extended channels.
-
- AIN14 is internally connected to an internal temperature sensor.
- AIN15 is internally connected to GND. Useful for measuring noise or looking at offset error.
- AIN16-AIN47 are optional extended channels that can be created with custom analog input muxing circuitry. See Section 14.2 Extended Channels for more information.
- AIN48-AIN127 are extended channels that are available when using a Mux80.
