Cable Name: CBL*_HDC_COM_IMU
Part #: 201083
Cable Name: CBL*_HDC_COM_IMU_XL
Part #: 201101
AsteRx2i_HDC only. These cables connect the AsteRx2i_HDC with an MTi IMU sensor. The “_XL”
version of the cable is longer than the other (5m vs. 1.8m).
Plugging this cable into I/O I connects the IMU with the receiver’s COM1 port. You will need to issue
the command
setDataInOut,COM1,MTi
to tell the receiver to use COM1 to communicate with
the IMU (see the “How To…” section of the Firmware User Manual for details).
Plugging this cable into I/O II connects the IMU with the receiver’s COM2 port. You will need to
issue the command
setDataInOut,COM2,MTi
to tell the receiver to use COM2 to communicate
with the IMU.
Cable Name: CBL*_HDC_COM2_COM3_GPIZ
Part #: 201236
AsteRx2i_HDC only. Dual COM cable with GPIZ. This cable must be connected to I/O II and gives
access to COM2 and COM3. Only the GND, Tx and Rx pins of the DSUB9 connectors are wired.
RTS/CTS handshaking is not supported.
Next to the two DSUB9 connectors, this cable features the following open-ended wires (check section
1.1 for the I/O II ODU pinout):

The yellow wire is typically used as ZUPT indicator when the COM3CTS line is configured as ZUPT
source with the command
setZUPTSource
.
Do not leave the red, purple and green wires floating. Tie them to ground if not used. This is to avoid
crosstalk effects that could lead to spurious level transitions on the EventA and EventB inputs.
1.3
Stand-By Mode
The receiver can be put in stand-by mode by entering the command “
exePowerMode, standby
”
(see Command Line Interface Reference Guide).
After having requested to enter stand-by mode, it takes up to 0.5 seconds for the receiver to actually
enter low-power state. This time is required to unmount the SD memory card and stop all software
activities.
Putting the receiver in stand-by mode is mandatory before shutting down the power supply if internal
logging is active.
