Chapter 1 Preface
1.1 Intended Use
The K2L MOST150 C-O Converter is intended to be used for connecting optical tools or
devices to a MOST150 system basing on a coax electrical physical layer (cPHY).
1.2 Scope of Delivery
The delivery covers the following:
MOST150 C-O Converter
Very short optical MOST cable
Coaxial cable
Power adapter cable for use together with OptoLyzer OL3150o / OptoLyzer MOCCA compact V3.1
Power supply (optional)
Check your shipment for completeness. If you have any complaints direct them to
[email protected]. Providing the delivery note number eases the handling.
1.3 Restrictions
The MOST150 C-O Converter does not contain any kind of PLL or signal recovery. As a
consequence this tool does not completely pass all MOST physical layer compliance tests.
The MOST150 C-O Converter cannot be used for physical layer tests.
The MOST150 C-O Converter can only be used for system test setups and demo setups.
The MOST150 C-O Converter and an optical tool have to be connected using a specific very short

Chapter 2 Introduction
The MOST150 C-O Converter is a small, compact device designated for connecting optical tools or
devices to a MOST150 system basing on cPHY. As it has no firmware or VHDL inside and there are
no additional control elements the MOST150 C-O Converter is easy to apply.
MOST150 networks can be built up as optical or as coaxial systems. In order to use the features of
existing optical-based MOST150 devices also in coaxial systems the MOST150 C-O Converter can be
integrated in coaxial systems by just connecting the MOST150 network to the coaxial interfaces of the
MOST150 C-O Converter. The optical MOST150 devices can be connected to the optical interface of
the MOST150 C-O Converter using the delivered optical MOST cable. Afterwards the MOST150
devices can be used for developing, testing, or analyzing coaxial MOST150 based multimedia products
and systems. The MOST150 C-O Converter indicates both ‘power is connected’ and ‘MOST signal is
detected’.
2.1 Feature Summary
The following list covers the key features of the MOST150 C-O Converter:
Compact housing
Easy usage
Multiple hardware variants available (see homepage: http://www.K2L.de)
Combined power supply possible for MOST150 C-O Converter and OptoLyzer OL3150o or
MOST150 C-O Converter and OptoLyzer MOCCA compact
No firmware or VHDL inside
Indication of power detection for both connectors (optical and coaxial)
Indication of MOST signal detection for both connectors (optical and coaxial)

2.2 Block Diagram
Figure 2.1 shows the features available for the MOST150 C-O Converter.
Figure 2.1 Block Diagram
The electrical MOST signal received via the Rx coaxial cable (1) is converted inside the MOST150
C-O Converter (2) and sent to a MOST150 device (oPHY) via the FOT (3). This MOST150 device
(e.g., an OptoLyzer OL3150o or an OptoLyzer MOCCA compact V3.1) (4) processes the optical MOST
signal and sends it back to the MOST150 C-O Converter where it is received via the FOT (5). Inside
the MOST150 C-O Converter the optical MOST signal is converted to an electrical MOST signal (6)
and sent via the Tx coaxial cable (7) back into the MOST150 system basing on cPHY.
The LEDs (8) inform whether the MOST150 C-O Converter is connected to power or about the
detection of a MOST signal (either optical or electrical).

Chapter 5 Typical Use Case - Connection Diagram
The Figure 5.1 below shows the connection diagram for a typical use case.
Figure 5.1 Typical Use Case: Connection Diagram
The instructions below describe how the MOST150 C-O Converter can be connected:
1. Power off all devices.
2. Connect the coaxial electrical panel of the MOST150 C-O Converter to a MOST150 system using
the delivered coaxial cable (1).
3. Connect an optical MOST150 device (e.g., an OptoLyzer OL3150o or OptoLyzer MOCCA compact
V3.1) to the optical panel of the MOST150 C-O Converter using the delivered, very short MOST
cable (2).
4. In case an OptoLyzer OL3150o (or OptoLyzer MOCCA compact V3.1) is used as optical MOST150
device, connect the delivered power adapter cable with the power supply pack (3) of the OptoLyzer
OL3150o (or OptoLyzer MOCCA compact V3.1) as shown in Figure 5.1.
Alternatively if neither an OptoLyzer OL3150o nor an OptoLyzer MOCCA compact V3.1 is used,
connect a power supply pack that has to be ordered separately (not part of shipment). Proceed
with step 6.
5. Connect both OptoLyzer OL3150o (or OptoLyzer MOCCA compact V3.1) (4) and the MOST150
C-O Converter (4) with the delivered power adapter cable as shown in Figure 5.1.
6. Power the devices.
