CONFIGURE BASIC HOST UNIT PROPERTIES
1 In the System Tree, click on the Host icon.
2 In the Unit Menu bar, click Unit Configuration > Edit Properties, to open the Unit
Configuration > Edit Properties page.
3 In the Name box, enter an identifying name for the Host. The Name must start
with an alphabetical character, contain between 5 and 40 characters
(alphanumeric or underscore only), and contain no spaces.
4 (Optional) The SeRF board on each Host and Remote contains the clock for that
unit. At the Remote, the reference is a clock derived from the Host clock. The
10 MHz Reference Clock default is Internal. You can change the 10 MHz Reference Clock
setting to External, which allows you to frequency lock the clock to an external
10 MHz reference.
CAUTION! When using the 10 MHz external reference clock, the signal must be connected to the Host
before enabling the clock in the software. If an external 10MHz reference clock is selected
for operation, but is not present or outside of the frequency range of 10MHz +/- 5ppm,
communication between the Host and Remote over the optical fiber will fail.
5 In the System Card Output Clock list, select one of the following:
• 10 MHz to set the Host as the System Card Output Clock.
• Off to disable the System Card Output Clock. Unless your system requires
the 10 MHz output, it is best to leave the System Card Output Clock disabled, as
this setting saves power and lowers emissions.
• 30.72 MHz is not applicable to a Prism system and should not be selected.
