Note. OTT 1812 module shown, the OBD 1210 is identical in terms of mounting
Connections
The MADI coaxial inputs and outputs are connected to the
corresponding 75 Ohm BNC connections provided. The ber
connection os on the SFP sub module as indicated on the module.
The module uses a single bidirectional ber link which is a LC simplex
connection. Please ensure the ber cable used is Singlemode
(Multimode cable will not work)
The module ber connection is supplied with a rubber plug installed,
this is to prevent dust contamination. Please retain the plug and use if
the cables are ever disconnected from the module. An example of a LC
connector is shown below:
Operation
The OBD 1210 kit is supplied as a matched pair (one “Type A” and one
“Type B” module) and are used to convert coaxial MADI signals (up to
64 channels IN and OUT) into a single bidirectional ber link for use in
long distance applications. The electrical / optical conversion
introduces no delay (zero latency) and there is no signal degradation.
Operation if fully automatic (plug and play) there are no user
adjustments for the module. The module supports hot swapping and
hot plugging of all connections.
NOTE
The modules use a single bidirectional ber link. This is WDM using
1310nm and 1550nm wavelengths. The modules should only be used in
point to point applications, and should not be used in a multiplexed
CWDM system (Even if the 1310 and 1550 CWDM ports are available)
Power Lead Strain Relief
The modules have a small hole in the case located above the power
connection to prevent the power lead being accidentally pulled out.
Use the supplied tie-wrap and secure the lead as shown below.

Optional Mounting Bracket
The optional RFR 1001 mounting brackets can be
used to permanently mount the modules on any
at surface or on 19” rack rails.
Power
The module requires a 7-16VDC power input (12VDC nominal) an LED is
provided to conrm power is connected. A 12VDC power supply is
provided, but if applying your own power, please provide a clean
7-16VDC power source. Each modules power consumption is approx
2.6W
Do not exceed 16VDC power input as module damage will result
