Sync Cable Installation
Description
The section provides the instructions for installing the two types of
synchronization (Sync) cables to the Metropolis
®
DMXtend.
A Sync cable is required if the shelf is to be externally timed. The
Metropolis
®
DMXtend can provide DS1 external timing to a BITS
clock. When the shelf is externally timed by a DS1 Reference and/or is
configured to provide a Sync Output, a Sync Input timing cable is
required.
This procedure should be performed on each Metropolis
®
DMXtend
shelf requiring an external timing source. There are two types of cables
available:
1.
Sync cable with a molded D-Sub 9-Pin (DB-9) connector
2.
Sync cable with a wire-wrap DB-9 connector.
See Table 1-22, Synchronization Cable Assemblies (SYNC1 and
SYNC2) (page 1-65) for ordering information.
Important!
Each of the Sync connections on the backplane may
provide an input (gray) and output (red) termination for timing.
Refer to Table 1-23, Synchronization Cable (DS1 Timing Reference)
Connections (page 1-66) for the pinouts.

Sync Cable with Molded
DB-9 Connector Procedure
Perform the following steps when using a Sync cable with a molded
DB-9 connector.
Step 1
Connect the DB-9 connector end of the Sync cable to the
SYNC1
(
J11
) port on the Metropolis
®
DMXtend backplane. Refer to
