Caveats
Saturn Tally will only tally sources switched on its own internal matrix. A multi–channel system is possible, but would
require an MI 3040 connected to each Saturn channel. Additionally, Saturn will not tally sources switched through an
external router.
Saturn Tally cannot be configured to recognize dependencies, i.e., it cannot track a source back through upstream
switchers.
This version of Saturn Tally software has no provisions for Under Monitor Display (UMD) support. UMDs (the RP ver-
sions of which include tally lights) are installed and configured using an entirely separate procedure, as described on page
3–45.
Note: The Jupiter Tally software cannot tally sources that are connected directly to the Saturn internal matrix.
For more information about Jupiter Tally systems, refer to the Jupiter installation/operating manual.
Hardware Installation
The MI 3040 used to control the tally lights must be connected to the MPK port on the Saturn video processor.
Relay outputs: The MI 3040 provides 40 electrically isolated output connections for operating tally lights, using solid–
state switches which are suitable for low–voltage (<100 V), low current (<300 milliamps) applications. The order in
which these connectors are wired to the individual tally lights is not determined by the Jupiter Tally Relay Description
table; rather, it is automatically chosen by the system—generally based on the order of sources defined in the Saturn Input
set. See Relay Assignments on page 3–8.
Opto inputs: these are not used in Saturn Tally.
Current Sources
In many cases, current sources will have to be found to operate the tally lamps. Although +5 V and ground utility connec-
tions are available on the back panel of the MI 3040, this supply may not be sufficient for the particular installation. Be-
fore attempting these connections, please refer to the hardware overview of the MI 3040 in Section 2 of the Jupiter Instal-
lation and Operating manual.
Software Configuration
An entry must be made in the MPK Device Table for the MI 3040 tally box and a special entry must be made for the Saturn
master control. See page 3–7.
