Connections
The coax MADI in- and outputs are connected to the corresponding 75
Ohm BNC connections provided. The fiber connection is made to the LC
connector as indicated on the module. An example of a LC connector
shown below.
Note:
The module is designed for use with SMF
(Singlemode) fiber cable.
Use the included dust plug to protect the optical connection from dust.
18 wavelengths are available to choose from when ordering the
module.
Operation
The OTR 1240 exclusively supports transmission of MADI signals
according to AES10-2008. It is used to convert coaxial MADI signals (up
to 64 channels IN and OUT) into CWDM fiber for use in long distance
multiplexing applications. The electrical / optical conversion introduces
no delay (zero latency) and there is no signal degradation.
Operation if fully automatic. There are no user adjustments for the
module. The module supports hot swapping and hot plugging of all
connections.
Note:
If TX LED is OFF this indicates no SDI input is present, or the input signal
is not valid. If RX LED is OFF, then this indicates that no optical input signal is
connected or the optical input power is too low.
Power
The module requires a clean 12V DC (7-24V DC) power source. An LED
is provided to confirm power is connected. A 12V DC power supply is
included with the module. If you are applying your own power source,
please provide a clean, 7-24V DC power source. Power consumption
information can be found in the technical specifications table.
Power Lead Strain Relief
The module has a small hole in the case which is located above the
power connection. This prevents the power lead being accidentally
pulled out. Use the supplied tie-wrap and secure the lead as shown
below.
Optional Mounting Solutions
The optional RFR 1001 mounting bracket can be
used to permanently mount the module on any
surface or on 19” rack rails.
The optional RFR 1000-1 rack mount can be used to permanently
mount up to 14 yellobrik modules. In addition, the RFR 1000-1 can
provide full power redundancy for all mounted yellobriks.
Note:
The OTR 1240 is identical in terms of mounting and securing.
