Description:
Enables sending or receiving of streaming MPEG over the network using UDP protocols. Prior
to use, multicast group IP and Port addresses must be specified to support the sending or
receiving operations. MMO is used when the unit is on a LAN or WAN receiving IP streaming.
The command format has been modified to allow for multiple decode channels in a single unit.
At this time, only channel 0 is supported.
If a decoder error is detected, the system will stop multicast playback to recover
from the error. Multicast playback will be automatically restarted after wating for
the number of milliseconds configured in the MCASTERRRECOVER configuration.
The default recovery time is 10000 milliseconds.

Channel List (args are not case sensitive):
Terse Verbose Description
CHn CHn The MMO will be set for channel n, where n is a
valid channel number, starting at 0.
If no CHANNEL is argued, the system will default to CH0.
Argument List:
Terse Verbose Description
0 OFF Turn off multicast
1 RECEIVE Enable Multicast receive
Note the following arguments are not currently supported:
2 SEND While video is played, stream out the data via Udp
3 SDPRECEIVE
4 SDPRECORD
5 SDPRCVRECORD
6 SDP247RECORD
7 SDPSEND
Response:
MODIFY MULTICASTMODE RESPONSE
Verbose- "OK\r\n" to acknowledge receipt of command, or
"ERROR- [Description]\r\n" if error, ending command
Terse- "0\r\n" to acknowledge receipt of command, or
"[NON-ZERO NUMERIC VALUE]\r\n" if error, ending command
"\r\n" concludes modify responses (empty line)
DISPLAY MULTICASTMODE RESPONSE
Verbose- "OK\r\n" to acknowledge receipt of command, followed by
"MULTICASTMODE CHn= [MODE NAME]\r\n", or
"ERROR- [Description]\r\n" if error, ending command
Terse- "0\r\n" to acknowledge receipt of command, followed by
"[MODE NUMBER]\r\n", or
"[NON-ZERO NUMERIC VALUE]\r\n" if error, ending command
"\r\n" concludes display responses (empty line)
Examples:
Verbose command to retrieve current setting:
*.DCMD MULTICASTMODE <enter>
Response is: OK\r\n
MULTICASTMODE CH0= OFF\r\n
Terse command to retrieve current setting:
*.DCMD MM <enter>
Response is: 0\r\n
0\r\n
Verbose command to set CH0 to receive using the default CHANNEL:
This will set CH0 to receive:
*.DCMD MULTICASTMODE 1 <enter>
Response is: OK\r\n
Verbose command to change setting while specifying a channel:
*.DCMD MULTICASTMODE CH1 RECEIVE <enter>
Response is: OK\r\n
Terse command to change setting while specifying a channel:
*.DCMD MM CH1 1 <enter>
Response is: 0\r\n
