2G Device Settings


Overview

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.


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.

astparam s [parameter]

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


Settings

Audio

Modify the way Transmitter services are processed.

Name Parameter Value(s) Description Applicable Units Example
TX Audio Handling v_rx_drv_option 0 Default on non-AVP TX.
Preserve audio sampling from source.
All TX astparam s v_rx_drv_option 6
2 Default on AVP TX.
Convert audio to 48kHz.
6 Enable audio services without video present.
Only applicable to AVP TX.

DHCP Server

Allow a Just Add Power Receiver to hand out IP addresses to other devices. Allows for direct IP access to devices connected to 509POE Daisy Chain Receivers. DHCP Server will hand out IPs from x.x.x.200-.249.

Name Parameter Value(s) Description Applicable Units Example
DHCP Server dhcp_server_enable n Default. Disable DHCP server. All RX astparam s dhcp_server_enable y
y Enable DHCP Server

Image Pull

Snapshot the video on a Transmitter or Receiver. The snapshot can be accessed by any device on the netork.

Name Parameter Value(s) Description Applicable Units Example
Image Pull pull_on_boot n Default. Disable Image Pull. All devices astparam s pull_on_boot 320_1_1
$A_$B_$C $A = size of the image. 160, 320, 640
$B = 1. Lower priority than video.
$C = Frequency of Image Pull. 0 means 10fps. 1 means 1fps.

IP

Name Parameter Value(s) Description Applicable Units Example
Mode ip_mode autoip Device defaults to 169.254.x.x All devices astparam s ip_mode static
static Consistent IP address. Must also assign ipaddr, netmask, gatewayip
dhcp Get IP from DHCP server. If no server, reboot until server is present
IP Address ipaddr $A.$B.$C.$D IP address for device in IP Mode Static All devices astparam s ipaddr 10.0.0.2
Subnet Mask netmask $A.$B.$C.$D Subnet mask for device in IP Mode Static All devices astparam s netmask 255.0.0.0
Default Gateway gatewayip $A.$B.$C.$D Default gateway for device in IP Mode Static All devices astparam s gatewayip 255.0.0.0

Serial/RS232

Send RS232 commands to endpoint devices using the RS232 port on any Just Add Power device.

Name Parameter Value(s) Description Applicable Units Example
Set TX-RX Link Dependence soip_type2 y Default. RS232 uses RX-TX link. All devices astparam s soip_type2 y
n RS232 does not use RX-TX link
Set SOIP Input soip_guest_on n Default. SOIP input is RS232 port of TX/RX. All devices astparam s soip_guest_on y
y SOIP input is network socket directly to device.
Set Baudrate s0_baudrate $A-8n1 $A = baudrate. Default = 9600. All devices astparam s s0_baudrate 115200-8n1

A combination of these functions translate to the different Serial Over IP Modes available to Just Add Power devices.


USB

Mode Usage Setting
Dumb Redirection Input: serial to TX
Output: serial from every RX watching that TX.
astparam s soip_type2 y;astparam s soip_guest_on n;astparam save;sleep 1;reboot
Guest Mode Two-direction with feedback
Input: network connection to IP port 6752
Output: serial from the device with that IP
astparam s soip_type2 y;astparam s soip_guest_on y;astparam save;sleep 1;reboot
CLI Access One-direction - no feedback
Input: network connection to IP port 23
Output: serial from the device with that IP
astparam s soip_type2 n;astparam s soip_guest_on y;astparam save;sleep 1;reboot
Name Parameter Value(s) Description Applicable Units Example
Touchscreen Enable no_kmoip n Default. Touchscreen disabled. Smoother mouse movements. All devices astparam s no_kmoip y
y Touchscreen enabled. Less-smooth mouse movements.

Video

Name Parameter Value(s) Description Applicable Units Example
1080i Handling v_1080i_to_720p y Default. Process 1080i as 720p All 2G TX astparam s v_1080i_to_720p n
n Process 1080i as 1080p.
HDCP Handling
Only one of these settings can be 'y'
v_reject_hdcp n Default. Handle HDCP according to device hardware. All TX astparam s v_reject_hdcp y
y Report as HDCP non-compliant device.
hdcp_always_on n Default. Handle HDCP according to device hardware. astparam s hdcp_always_on y
y Report as HDCP 1.4 compliant regardless of source settings
Disable RX HDMI when video lost v_turn_off_screen_on_pwr_save n Default. Show debug screen when video lost All RX astparam s v_turn_off_screen_on_pwr_save y
y Stop HDMI output when video lost.
Timing based on v_src_unavailable_timeout value.
v_src_unavailable_timeout $A $A = time in ms (1000ms = 1sec) before HDMI dropout All RX astparam s v_src_unavailable_timeout 5000
Debug Text ui_show_text y Default. Show text on debug screen. All RX astparam s ui_show_text n
n Hide text on debug screen.
