Analogue Input |
8 differential Analogue inputs
with a range of +-5Volts simultaineously sampled with 16 bits at up to
250K samples per second. Uses main connector for signal lines. |
2 |
Digital I/O |
8 bits of bi-directional digital
I/O on main connector. Untested |
4 |
Counter/Timers |
2 Counter timers. Untested. |
5 |
Calibration |
Calibration devices. Sets up
calibration source including PWM signal. PWM signal setting is untested. |
6 |
Memory |
EEPROM containing configuration
parameters. Untested. |
7 |
Digital I/O |
PFI trigger lines on main
connector. These lines can be set for input or output and can be used
as triggers for capture events. |
9 |
Serial |
Serial device interface.
Calibration DAC's have not been tested. Untested. |
10 |
Digital I/O |
RTSI bus on secondary connector.
This bus provides bi-directional digital lines for synchronsing boards
together. |

API Command |
Description |
---|---|
INSN_CONFIG_SET_RTSI_CLOCK_MODE |
This sets the boards main clock
mode. The argument defines the setting as one of: COMEDI_RTSI_CLOCK_MODE_INTERNAL - Internal Clock COMEDI_RTSI_CLOCK_MODE_OUTPUT - Run from internal clock and output this on the RTSI bus bit as RTSI_7 COMEDI_RTSI_CLOCK_MODE_SLAVE - Run from the clock on the RTSI bus bit RTSI_7 COMEDI_RTSI_CLOCK_MODE_MASTER - Output the clock on the RTSI bus bit as RTSI_7 and run from this external clock |
INSN_CONFIG_DIO_OUTPUT |
Configure the "channel" bit as
an output. Channel is one of NI_RTSI_[0-6] |
INSN_CONFIG_DIO_INPUT |
Configure the "channel" bit as an input. Channel is one of NI_RTSI_[0-6]. |
INSN_CONFIG_DIO_QUERY |
Find the direction of one of the RTSI "channels". Channel is one of NI_RTSI_[0-6]. |
