Overview

The “Console APIs” interface is so called “Command Line Interface” (CLI). This document

describes the commands which can be used under HKM01B-4K series’ platform’s console

interface. HKM01B-4K uses Linux OS and the console is derived by Bash shell. Console

can be accessed through:

● Debug console: is set to UART port 2 using baud rate at 115200-8n1.

● Telnet port 24: There is built-in telnet server to connect to HKM01B-4K devices.

● Web CGI: Controlled through web protocol. Mapping CGI command to console

command.

Through console APIs, developers can get more control on HKM01B-4K firmware and

extend product's features and capability.

Supported Platform

● AST1520

● AST1525

● AST1510: Only supports commands introduced before A7.0.0. FW >= A7.0.0

doesn’t support AST1510 platform.

● AST1500: Only supports commands introduced before A7.0.0. FW >= A7.0.0

doesn’t support AST1500 platform.

Supported FW Version

Supported FW version is listed in each command. This document is based on A7.0.0.

Terminology

Term. Description

HKM01B-4K Refers to all series of AST1500, AST1510, AST1520.. platform.

AST152X Refers to AST1520 and AST1525.

host The HKM01B-4K video encoder board.

Tx Same as ‘host’.

client The HKM01B-4K video decoder board.

Rx Same as ‘client’.

node Generic term for ‘host’ and ‘client’.

device Same as ‘node’.

FW Short of ‘firmware’. Normally refers to HKM01B-4K’s firmware.

HW Short of ‘hardware’. Normally refers to HKM01B-4K’s HW platform.

console FW’s command line interface (CLI).

console API FW provides commands through console as API.

Link Manager A major FW script/program handling most of user space link

management.

astparam A command to access parameters in flash. Also refer to those

parameters accessed through this command.

lmparam A command to access internal parameters of ‘Link Manager’. Also

refer to those parameters accessed through this command.

event Normally refers to control commands sending to ‘Link manager’.

service HKM01B-4K provide many over IP extension functions. It is called

‘service’ in general. For example, video over ip, usb over IP….

channel Most of over IP streaming ‘services’ using different multicast

IP/group. To simplify the process of choosing multicast IP, we use

‘channel’ to represent/mapping each service’s multicast IP/group.

Normally, each host has its own unique channel setting. So that

client can choose which host to connect to by specifying the host’s

‘channel’ number.

switch channel The process of changing ‘channel’ number.

sink Video sink. Refer to TV, monitor which attached to HKM01B-4K’s

client video output port or HKM01B-4K host’s video loopback output

port.

source Video source. Refer to video player whichever feed HDMI/DVI video

signal to HKM01B-4K host.

OSD Stands for “On Screen Display”. Client display HW engine ‘overlay’

function to overlay 16bits RGB565 data onto video decode picture.

FW provide ‘String OSD’ and ‘Picture OSD’ APIs for overlay string or

picture onto video decode picture.

USBoIP Short of ‘USB over IP’ extension function. Specially refers to

‘transparent’ type of ‘USB over IP’ extension function. Comparing to

‘KMoIP’ which is ‘emulation’ type.

KMoIP Short of ‘Keyboard/Mouse over IP’ extension function. It is a kind of

USB extension, but uses ‘emulation’ technology instead of

‘transparent’ USBoIP.

Preface

How to Access the Console

There are 3 ways to access the console:

1. UART2 debug port: It is a RS232 interface using 115200-8n1 baudrate setting.

Developer can attach to this debug port to access console.

2. Use telnet: FW has built-in telnetd server and telnet client built in. Developer

can use any telnet client to connect to any HKM01B-4K board. Or write their own

program using telnet protocol to connect to any HKM01B-4K board through IP

network. NOTE: Default use telnet port 24 instead of 23. Use "root" to

3. Use Web CGI: FW has built-in web server and has a CGI command to mapping console

commands to CGI. Check the Web UI ⇒ System ⇒ Utilities ⇒ Console API Command.

Use telnet or web protocol are recommended way for developing control software.

UART2 debug port is usually used for engineering test and debug. By default, debug port

will output a lot of debug messages. You can turn it off.

How to get HKM01B-4K board's IP address

FW default runs "autoip" and uses 169.254.xxx.xxx private IP domain. The IP of target

HKM01B-4K board is resolved by its hostname using mDNS protocol. If developers want

to use "static ip" or "DHCP client", developer will be responsible to maintain the "IP to

board" mapping by themselves. Here are the methods to resolve the IP address using

"autoip" mode.

● Client's GUI: The client's GUI will display the client's IP address and connected

host's IP address.

● Console APIs: Following console APIs are provided:

○ [FW >= A7.0.0] node_query: An enhanced version of node_list. See

“Node Discovery and Query” section for details.

○ [FW < A7.0.0] node_list: use this command to list all HKM01B-4K

boards' hostname and IP address.

○ astresname: use this command to resolve a target's IP address by

providing target's hostname.

● From PC: Following methods are provided:

○ For end users, please reference to “Documents/Web UI/How to Connect to

Web UI” document.

○ Developer can use/implement ASPEED proprietary discovery protocol.

Reference to “node_query” or “node_list” sample code. There is pre-

compiled execute files for Windows OS under “Documents/Console

APIs/SampleCode/”.

○ Use the mDNS libraries. For example:

■ Bonjour: http://developer.apple.com/networking/bonjour/

■ pyZeroConfig: http://sourceforge.net/projects/pyzeroconf/files/
