NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH VIA CAT5
17
Telnet Interface-Port 2005
For a software control type of telnet interface session (versus operator telnet control through port 2000 as described on page 16),
connect to the VEEMUX through the current IP address at port 2005. To do this, a connection to port 2005 must first be enabled
(see Web Setup on page 23). Then, with port 2005 enabled, use the command set below to control and acquire information from
the VEEMUX.
Command Summary
Command String Good Response Description
RU<CR> ru OP,IP<CR> Read unit size
RO OP<CR> pc OP,IP<CR> Read connection for OP
CS OP,IP<CR> *<CR> Connect OP to IP
CA IP<CR> *<CR> Connect all outputs to IP
SS 01<CR> *<CR> Enable auto-status mode
SS 00<CR> *<CR> Disable auto-status mode
SX<CR> See details Examine connections
XX<CR> *<CR> Close connection
A <CR> (carriage return, 0x0D) is considered to be the end of the command string. If a string exceeds 16 characters, an end of
string will be inserted automatically to avoid buffer overflow. An eventual <LF> (line feed, new line, 0x0A) after a <CR> will be
ignored. A bad string will always be responded to with the ASCII character
‘ ? ’ followed by a <CR>.
Command Detail
RU-Read Unit Size
Command:
Byte 1 Byte2 Byte3
‘R’
(0x52)
‘U’
(0x55)
<CR>
(0x0D)
Response:
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8 Byte 9
‘r’
(0x72)
‘u’
(0x75)
Space
(0x20)
Output – 1st digit
(0x30 … 0x32)
Output-2nd digit
(0x30…0x39)
‘
,
’
(0x2C)
Input – 1st digit
(0x30 … 0x32)
Input – 2nd digit
(0x30 … 0x39)
<CR>
(0x0D)
This command will read the size of the unit. The response returns the number of inputs and the number of outputs in two-digit,
ASCII code format. If the numbers are smaller than 10, the 1st digit is ‘0’.
RO-Read Connection for Output Port
Command:
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6
‘R ’
(0x52)
‘ O ’
(0x4F)
Space
(0x20)
Output – 1st digit
(0x30 … 0x32)
Output – 2nd digit
(0x30 … 0x39)
<CR>
(0x0D)
Response:
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8 Byte 9
‘p’
(0x70)
‘c’
(0x63)
Space
(0x20)
Output – 1st digit
(0x30 … 0x32)
Output-2nd digit
(0x30…0x39)
‘
,
’
(0x2C)
Input – 1st digit
(0x30 … 0x32)
Input – 2nd digit
(0x30 … 0x39)
<CR>
(0x0D)
This command will read the connection of an output port. The response returns the output port that is connected to the input port.
Notes:
•
If Port 2005 connection is idle for 10 seconds it will disconnect
•
Up to 2 active connections are allowed at the same time
•
After establishing the connection, the unit will answer with *<CR>. If the connection fails or there are already 2
connections established, it will answer with ?<CR>
