Generally it be must distinguished among six kinds of ports:
1. TCP and UDP audio ports
Here the ports are determined by the first audio port. The first audio port is 2001 by default and it can be set by the direct command ‘ip_audioport’(see menu item Expert/Direct Command).
All the default IP ports of 
are listed in the appendix of the Communication Reference Manual (www.mayah.com/content/download/pdfs/manuals/communication-reference_man.pdf).
2. Remote control port
The remote control port is:
IP remote port := first IP audio port - 1
Therefore the default IP remote port is 2000.
3. RTP audio ports
By default the RTP audio ports are:
a) System version < x.2.0.30:
- Sub codec 1: 5004 and 5005 (for RTCP)
- Sub codec 2: 5006 and 5007 (for RTCP)
- Sub codec 3: 5008 and 5009 (for RTCP)
- Sub codec 4: 5010 and 5011 (for RTCP)
b) System version >= x.2.0.30:
- Sub codec 1: 5004 and 5005 (for RTCP)
- Sub codec 2: 5014 and 5015 (for RTCP)
- Sub codec 3: 5024 and 5025 (for RTCP)
- Sub codec 4: 5034 and 5035 (for RTCP)
Note:
x = 2 for CENTAURI and x = 3 for CENTAURI II, MERKII and GANYMED 1102
However, the RTP audio ports can be changed at establishing the connection by enhancing the IP-address with the delimiter ‘:’ and the requested RTP port.
For instance:
225.0.0.11:5015
This establishes a connection to Multicast address 225.0.0.11 using the port 5015.
4. SAP port
SAP announcements are sent on port 9875. You can get more info about SAP at SAP streaming.
5. UDP level information
This remote control software makes sending out its level information at port 2060.
How to activate level display is described in help chapter of menu item <Expert/Options> at item level meter interval.
6. UDP Scan
By default the port for UDP scan (for available 
) is incremented by every UDP scan. At first UDP scan it starts with port 2061.
However, the port for UDP scan can be set to a fixed value by a registry entry. This not officially supported feature is described in the readme file ‘README_Static_UDP_Port.txt’. If you are interested in this file, please contact support@mayah.com.
