I can't connect to my Pharos LPC on the Control Subnet?

If a Pharos LPC is located on a Crestron processor's Control Subnet, then it is necessary to create a port map on the processor in order to access the Pharos from the LAN-side of the processor. 

In addition to the below ports, it is necessary to ensure that the CS and LAN networks are not isolated using the isolatenetworks command.

Ports can be added to the portmap with the addpo [ext_port] [int_port] [target_ip/target_hostname] [protocol] command, and ports can be removed with the rempo [ext_port] [int_port] [target_ip/target_hostname] [protocol] command. The current port mapping can be viewed with the showportmap command. 

The table below includes an example of how ports could be set up in order to access a Pharos on a processor's Control Subnet from the LAN-side of the processor. The external port can vary, but it must not be in the range reserved by the processor for dynamic ports (default 64000 thru 64301). We recommend using ports above this range (e.g. 64302). 

If DHCP is enabled on the Control Subnet and the Pharos LPC has DHCP enabled, then the Pharos's IP address can be found by running the dhcplease command and looking for the device with hostname "lpc-[pharos SN]". If DHCP is disabled on the Control Subnet or if the Pharos has a static IP address then it may be necessary to connect via USB to determine the Pharos's IP address. 

Ext. PortInt. PortTargetProtocolPurpose
6439938008Pharos IP address or hostnameBothAllows connection to the Pharos from Pharos Designer 2
6439880Pharos IP address or hostnameTCPAllows HTTP connections to Pharos web interface
64397443Pharos IP address or hostnameTCPAllows HTTPS connections to Pharos web interface

With the above example mapping, the Pharos web interface would be reachable by using a web browser to connect to "http://[processor LAN IP address]:64398" or "https://[procesor LAN IP address]:64397". Note that most web browsers assume HTTPS, so it is necessary to include "http://" if attempting to connect via HTTP. 

With a project open in Pharos Designer 2, the Pharos can be connected to by navigating to the "Network" page, selecting a controller, and clicking the "Find" button on the right, and entering "[processor IP address]:64399".
