Overview
The 3G System includes all 2GΩ/3G and 3G devices. Essentially, any device in a black metal casing.
Settings on Just Add Power alter the behavior of the device upon start-up. Settings that are changed will not be active immediately; they will be applied upon the next start-up. Many settings should be altered according to the unique situation present in each installation and are not recommended as blanket settings for all systems.
Requires devices to be on justOS firmware version B1.0.0 or later.
For Commands that change the behavior of a device instantly, see the 3G Device Commands article.
Access
All Settings should be entered via the Command Line Interface accessible via:
- Telnet to the IP of the unit, at port 23
- RS232
- White, 3-pin molex connector on the bottom of the unit. Make or request a Debug Cable to access.
- 115200-8n1 baud rate
All Settings are case-sensitive.

Chaining Settings
Multiple commands can be chained together to be applied simultaneously. Separate each command with a semicolon (;). Recommend adding Delay 1 Second after Save to ensure that the device has time needed to commit changes to permanent memory.
Example
astparam s ip_mode static;astparam s ipaddr 10.0.0.2;astparam s netmask 255.0.0.0;astparam s gatewayip 10.0.0.2;astparam save;sleep 1;reboot
