BASIC TALLY SYSTEM WITH SATURN MASTER CONTROL SWITCHER
Direct Connection to Transmitter
Please see Figure 5−142.
This table has only one type of entry: MCS_TLY.
Saturn (“MCS_TLY”) entries
These entries are used in systems equipped with a Saturn Master Control Switcher (or BTS MCS 2000). They allow
the Jupiter system to find out which of the sources feeding the master control switcher have been switched to the MCS
“On−air” output. There are always five entries for the MCS 2000, one for each of the five inputs from the routing
switcher. For the Saturn, there are seven entries.
The source of the Name used here is the MPK Devices table (for discussion, see page 5−115). As a convention, the name
“MCS_TLY” is used.
The Opto−isolator number entries must be assigned as follows:

Note 1: The device called “MCS_TLY” and the “opto−isolators” associated with it exist only in software ta-
bles.
Note 2: There are no entries for MCS 2000 Mix 1 and Mix 2 (these are audio inputs). If the MCS 2000 is
mixing or keying, then both the mix source and the key source will be tallied by the Jupiter system.
The Switcher Outputs are the names of the five router outputs leading to the master control switcher. The source of
the switcher output names is the Switcher Output table (page 5−55).
The MCS_TLY entries do not include a dependency on a relay, since no tally light is associated with the master control
switcher. (There is no tally light because in this system the master control switcher is always on−air.) The last two col-
umns are therefore left blank.
