Options
Scan Rate
You must select the correct scan rate for your system for board up−time to be displayed correctly:
NTSC - Select this if you use NTSC.
PAL - Select this if you use PAL.
Time Sync
(Applies to VM only.) This enables the JNS time synchronization server, which syncs the PC’s clock to the
existing time of the Jupiter system (VM time).
VM time is derived from the following (in order of priority):
1. Time code (if present) (VM connection to a time code source is recommended)
2. Switcher Esbus protocol source (e.g. automation computer) (if present)
3. VM internal clock (if previously set from time code)
4. PC clock (if Time Sync is enabled)
5. VM internal clock (if set by the file server)
6. VM internal clock
The PC is the only possible source of date information on the system.
Note: Windows XP servers have the option of using an Internet time server as a source. This is not recom-
mended.
