For convenience, the UHD-H2H-88M comes with DHCP on. This enables the matrix to be
connected to a network without knowing available IP addresses. If your network does not allow
dynamic IP addresses or if you are using the matrix with a TCP/IP control system, this feature may
be turned off and the IP address set using RS-232 commands or AMS.
To disable DHCP, use the following command: IPDHCP off. Once disabled, set the IP address using
the IPStatic command (e.g. IPStatic 192.168.1.56).
