10/100:
This Amber LED is ON when a 100Base-TX link is detected. The LED is OFF when a
10Base-T link is detected.
LN/ACT:
This dual purpose Green LED will turn on to indicate a valid link. This gives a good
indication that the segment is wired correctly. The LED will BLINK when sending or
receiving data. The LED will be OFF if there is no valid connection. The link status can
also be seen in the
ControlEthernet
status screen.
Note that on the Time Ethernet port, the function of the LEDs is reversed. The 10/100 LED is Green,
and the LN/ACT LED is Amber.
3.1.4. Linear Time Code and IRIG Connections
The
LTC 1
and
LTC 2
groups of sub-menus in the
OUTPUT
root menu are used to configure the LTC
and IRIG outputs. See section 4.4.1. The LTC output level is adjustable from approximately 0.8V to
9.0V using the
Output Level
menu item. The IRIG output level is controllable from approximately 1.0V
to 8.3V. This assumes a load impedance of greater than 1k
Ω.
There are two 3-pin male XLR connectors for SMPTE/EBU Linear Time Code. When the
IRIG
option is
installed, these outputs will also be able to provide IRIG timecode. They are labelled LTC OUT 1 and
LTC OUT 2. These XLR connectors are the primary copies for each timecode output. The LTC OUT 1
connector is capable of d12 V
DC
power for downstream Evertz clocks (see section 4.4.1.1).

Table 3-2: LTC OUT 1 and LTC OUT 2 XLR Pin Definitions
Secondary copies of the two LTC/IRIG outputs are available on the GPIO 15-pin female ‘D’ connector.
The pinout of this connector is shown in Table 3-5. When LTC power is turned on for LTC1, this
secondary output of LTC1 will not have +12V
DC
power but will provide an isolated copy of LTC1. For
details on wiring IRIG timecode, see section 2.3.5.
The primary LTC outputs on the XLR connectors are not fully isolated from the
secondary copies on the GPIO DB15 connector. This means a wiring fault (such
as a short) affecting an XLR output will also affect its copy on the GPIO
connector (the exception being for LTC1 when power is turned on).
