Iridium Configuration - Prototype units
Logger Configuration (firmware LOGR53 V3.10)
- Do normal logger setup first - must be LOGR53 V3.10 firmware (with Iridium support) - NTAS-type
firmware used on WHOTS currently
see LOGR53 Command Set for Ver 3.xx Firmware with Iridium Support
- In UOK setup, 3 parameters set for Iridium comms:
- CCD set for 15 minutes ON time at each interval
- CCI set for 4 hour interval
- RE set for 1 minute R-interval (RAM buffer holds max 255 one-minute records)
- A logger STAT command should show:
Logging Interval: 60
- A logger CCSTAT command should show:
or something similar. Significantly, the first digit is the hours interval in EEPROM
and the second digit is the minutes duration in EEPROM.
see LOGR53 Command Set for Ver 3.xx Firmware with Iridium Support for full info.
Comms Controller Configuration
Nothing to configure!
Note that the Iridium console cable pinout is standard ASIMET and LOGR53. Procomm or equivalent should be set for
BEFORE applying power to the Iridium console cable! Applying power at the Iridium console cable will switch power ON to the
comms controller. Procomm will display the startup messages then the Iridium SEND script messages, followed by the Linux system
prompt. This will cause an extra Iridium transmission if the logger currently has the comms controller power OFF. Remember that the
logger ALWAYS turns ON iridium power for the first hour after main logger power up, then for 15 minutes every 4 hours thereafter.
NOTE that removing power from the Iridium comms controller at anytime should be OK - a Linux shutdown is not necessary, as all
software resides in FLASH on the controller CPU board.
- Start logger as usual and confirm AOK
- Connect Iridium Controller box as follows (don't connect power control cable!):
- Connect Antenna
- Connect Comms Power (6-pin cable)
- Connect LOGGER console to Comms Controller input
- Connect a standard ASIMET/LOGR53 console test cable to the Comms Controller console connector.
- Connect this console test cable to a PC/Laptop with Procomm set for 38400 N81
- Apply power to the console test cable (this will switch on the comms controller batteries - this
does NOT need to be a big supply or battery. An old (but NOT dead!!) MET battery will do.
- Observe Linux startup messages, Iridium script messages, Linux prompt on success.
- Once above is successful, connect the power control cable between the logger and the comms controller.
- If still in first 60 minutes from power up of logger, comms controller will remain ON when power is removed
from console test cable. Otherwise, logger will power up the comms controller every 4 hours for 15 minutes
using the settings show above.
- that's all......
