Configuration
Intersite Port
This port is designated for communication between site controllers at permanently connected sites.
Site
The number that defines which site the unit controls. This site number is used as the units address.
The range is 1 to 100.
Default = 1
Remote Station
Defines how this unit talks to other site controllers.
Duplex
sets the inter-site communications to bi-directional and this site controller will both send and receive
messages.
Rx only
sets the inter-site communications to simplex and this site controller will only receive messages.
Default = Duplex
Baud Rate
Defines the baud rate at which the inter-site communications occurs.
Valid values are 1200, 2400, 4800, 9600, 19200, 28800, 38400,57600 and 128000.
9600 is recommended for systems of less than 6 site. Greater than 6 sites should use 19200. With many
active sites (i.e. operators at multiple sites controlling remote cameras) 57600 may give a better
performance.
Default = 9600
Turnaround Time
Also known as the transmit hold-off time, this configurable delay is designed to maximise compatibility with
different transmission media (such as fibre optics, radio etc).
Smaller values allow faster communications between sites, but require the transmission equipment to switch
between receive & transmit states quicker.
Value is configured in microseconds in the range 1 to 65535
Default = 4000
Priority
Bandwidth on the intersite port is allocated according to relative priorities.
On networks with more than 16 sites, it is recommended to set the satellite sites to Medium or Low priority, to
improve the performance at main control rooms when controlling cameras over the intersite network.
Options : High, Medium or Low.
Default = High
