Autodiscovery
CueServers on the network can be discovered by using an
auto-discovery
technique.
All CueServers (both the original CueServer and the CueServer 2 series) are listening on the CueServer
Multicast Group Address (239.255.204.2) on port 52737. This socket is typically used to send CueScript
commands to the CueServer, but it also used for auto-discovery.
To ask CueServers to report themselves, simply send the 6 character string
#PING#
via UDP to this group
address and port number.
Every CueServer that receives this message will reply to the sender with a UDP packet. The returned data
is an ASCII string. It begins with
#PING
and contains several fields, each separated by a bar character (
|
).
The following is an example ping reply packet from a CueServer:
#PING|600001|10.0.1.5|1.5.5|CueServer 2|255.0.0.0|10.0.1.1|0|239|
000000000000|6/30/2017 12:59:59 PM|N|shows/My Show|1|1|0.0.0.0|0.0.0.0|0
The bar-separated fields are explained in the following table:
