CLI Settings for 2G Series Devices

Jan 15, 2026

Overview

Startup settings on a Just Add Power device define how the unit behaves when it powers on. Any changes made to these settings are not applied immediately and will only take effect after the device is rebooted.

Many settings are intended for specific installation scenarios and should not be applied as global defaults across all systems. Use caution when modifying startup parameters, especially in live systems.

Access

All startup settings are configured through the Command Line Interface (CLI), accessible using one of the following methods:

Telnet
Connect to the device IP address on port 23
RS232
- White 3-pin Molex connector on the bottom of the unit
- Requires a Just Add Power debug cable
- Serial settings: 115200-8n1

All startup settings are case-sensitive.

Chaining Settings

Multiple commands may be chained together using semicolons (;) and executed as a single line. After saving startup parameters, it is strongly recommended to insert a sleep 1 delay before rebooting to ensure changes are written to permanent memory.

Settings

Audio

Controls how audio services are handled on Encoders.

Name	Parameter	Value(s)	Description	Applicable Units	Example
Encoder Audio Handling	`v_rx_drv_option`	0	Default on non-AVP Encoders. Preserves the source audio sampling rate.	All Encoders	`astparam s v_rx_drv_option 6`
		2	Default on AVP Encoders. Converts audio to 48 kHz.
		6	Enables audio services without video present. Applies only to AVP Encoders.

DHCP Server

Allows a Receiver to operate as a DHCP server for devices connected to the Just Add Power network. IP addresses are assigned in the range x.x.x.200 – x.x.x.249.

DHCP Server	`dhcp_server_enable`	n	Default. DHCP server disabled.	All Receivers	`astparam s dhcp_server_enable y`
DHCP Server	`dhcp_server_enable`	y	Enable DHCP server.	All Receivers	`astparam s dhcp_server_enable y`

Image Pull

Captures periodic still images from an Encoder or Decoder. Images are accessible to other devices on the network.

Name	Parameter	Value(s)	Description	Applicable Units	Example
Image Pull	`pull_on_boot`	n	Default. Image Pull disabled.	All 2G Series devices	`astparam s pull_on_boot 320_1_1`
		$A_$B_$C	$A = Image resolution (160, 320, 640)
			$B = Priority (1 = lower priority than video)
			$C = Capture rate (0 = 10 fps, 1 = 1 fps)

IP

Configures IPv4 addressing for Just Add Power devices.

Name	Parameter	Value(s)	Description	Applicable Units	Example
Mode	`ip_mode`	autoip	Defaults to a 169.254.x.x address.	All 2G Series devices	`astparam s ip_mode static`
		static	Uses a fixed IP address. Requires ipaddr, netmask, and gatewayip.
		dhcp	Requests an IP from a DHCP server. Reboots until one is available.
IP Address	`ipaddr`	$A.$B.$C.$D	Static IP address for the device.	All 2G Series devices	`astparam s ipaddr 10.0.0.2`
Subnet Mask	`netmask`	$A.$B.$C.$D	Subnet mask for static IP mode.	All 2G Series devices	`astparam s netmask 255.0.0.0`
Default Gateway	`gatewayip`	$A.$B.$C.$D	Gateway address for static IP mode.	All 2G Series devices	`astparam s gatewayip 255.0.0.0`

Serial / RS232

Enables RS232 communication through the serial port on Just Add Power devices.
