Model 5601MSC
Model 5601MSC Master SPG/Master Clock System
OVERVIEW Revision 2.2 Page - 9
Standard Time (CST) is UTC –6:00 hours. Mountain Standard Time (MST) is UTC –7:00 hours. Pacific
Standard Time is UTC –8:00 hours. The 5601MSC also supports Daylight Saving Time, which must be
enabled separately for each time output. Below are descriptions of the time outputs available from the
5601MSC:
Sync Outputs - When a Sync output mode is set to NTSC-M or PAL-B black burst, VITC time can be
inserted onto two lines in the vertical blanking interval. The VITC is controlled by the Vitc Enable, Vitc
Line 1, Vitc Line 2, Dropframe Ctl, Color Frame, Set Jam Time, Jam Output, Jam all VitcLtc, Time
Offset, Time Zone, and DST enable menu items.
LTC/IRIG Outputs - There are two Linear Time Code outputs from the 5601MSC. The primary outputs
are provided as XLR connectors on the back of the unit. Secondary copies are provided on the 15-pin
GPIO D-sub connector. The LTC outputs are configured in the LTC 1 and LTC 2 sub-menus located off
the OUTPUT root menu. If the IRIG option is installed, they can be configured to one of several IRIG-B
output modes.
NTP Server - If the 5601MSC has the T option installed, it will support the Network Time Protocol. This
is configured by pressing the GENERAL button and entering the NTP rules sub-menu. The 5601MSC
hosts an NTP server and also sends out periodic NTP broadcasts. NTP time should always be UTC.
Test Generator Outputs - If the 5601MSC has any of the test generator options installed, timecode
can be “burned-in” at the bottom of the test signal output. The time is controlled by the TC Burn In,
Dropframe Ctl, Set Jam Time, Jam Output, Jam all VitcLtc, Time Offset, Time Zone, and DST enable
menu items.
1.1.11. Final Steps of Set Up and Securing all Connections
Once the 5601MSC has been configured, the various STATUS screens should be checked to ensure
there are no items displayed with a red or yellow background. The left LCD screen should show “Sys
OK” and “Ref OK” with a green background in the bottom corners.
The power supply and fan modules (accessed by removing the front panel) should be secured to the
chassis by fastening the Phillips mounting screw. All D-Sub connectors on the back of the unit should
be secured to the 5601MSC using their mounting screws. The removable terminal block should also be
secured using the flange screws. The AC power cords can be fixed to the unit using the retaining clips
provided (see section 3.1.11).
1.1.12. Access Control
The engineering menu password can be changed from the default to prevent unauthorized tampering of
SNMP and menu access control settings. In the Menu Visibility sub-menu, each of the front panel
menus can be disabled to prevent local changes. The SNMP Ctl menu item can be changed to SNMP
off or SNMP status to prevent remote SNMP control of the unit. Furthermore, pressing the PANEL
LOCK button can lock the front panel. This prevents accidental changes by someone bumping or
leaning into the front panel. The front panel can be unlocked by pressing the SELECT and PANEL
LOCK buttons simultaneously.
