Automatic Changeover
Revision 1.0 Page 29
Type
Inputs: Opto-isolated input with internal pull-up to + 5volts.
Outputs: Normally closed relay to ground. 10K internal pull-up to + 5volts when relay is in
active position
Connector: 4 pins plus 2 ground pins on 16 pin removable terminal block
Signal Level: +5V nominal
4.4.5. MSC General Purpose Inputs and Outputs
Inputs 2 GPI inputs connected to both Master A and Master B with AUX option
Outputs 2 GPI outputs connected from Master A through AUXI/O A
2 GPI outputs connected from Master B through AUXI/O B
Connector 6 pins on 16 pin removable terminal block
Signal Level As specified in 5700MSC-IP manual
4.4.6. Changeover Conditions
Changeover is a voting system based on which source has the most valid signals and that the good
signals on the current master are also present on the backup master. The input signals are considered
good according to the following criteria:
Sync H timing detect
SDI/HDSDI Valid TRS ID
10MHz Level above 1.0Vp-p
Word Clock Level above 0.5Vp-p
DARS Sync word valid
LTC Level above 0.3Vp-p
Sync word valid
GPI Input high
4.4.7. Ethernet
Network Type Gigabit Ethernet 1000Base-T IEEE 802.3u standard for 1000Mbps baseband
CSMA/CD local area network
Fast Ethernet 100 Base-TX IEEE 802.3u standard for 100 Mbps baseband
CSMA/CD local area network
Ethernet 10 Base-T IEEE 802.3 standard for 10 Mbps baseband CSMA/CD local
area network
The 5700ACO is designed to be used with either 10Base-T (10 Mbps), 100Base-TX (100 Mbps) also
known as Fast Ethernet or 1000Base-T (1000 Mbps) also known as Gigabit Ethernet, twisted pair
Ethernet cabling systems. When connecting for 10Base-T systems, category 3, 4, or 5 UTP cable as
well as EIA/TIA – 568 100Ω STP cable may be used. When connecting for 100Base-TX systems,
category 5 UTP cable is required. When connecting to 1000Base-T systems, category 5 or higher UTP
