1. Introduction

Thank you for choosing the Hammerfall DSP series. This expansion board adds word clock
input and output in professional quality to the HDSP 9632. A transformer-isolated input, a
switchable termination and two low jitter outputs extend the powerful capabilities of the HDSP

9632.

2. Package Contents

Please ensure that all the following parts are included in the WCM's packaging box:

• Word Clock Module

• Flat ribbon cable, 10 pins

• Quick Info guide

• RME Driver CD

Note: The WCM needs no drivers and no additional software installation!

3. System requirements

• HDSP 9632

4. Power supply

The WCM gets its power from the HDSP 9632 via the supplied cable.

5. Brief Description and Characteristics

The 9632 Word Clock Module is a small companion board to RME's HDSP 9632, and needs no
slot on the motherboard. It adds word clock input and outputs to this powerful digital interface
card. All connectors are BNC jacks, so there's no hassle with adapters. The module includes a
transformer-isolated input, a switchable termination with LED indication, and two low jitter out­puts.

HDSP 9632 includes SteadyClock, guaranteeing an excellent performance in all clock modes.
Its highly efficient jitter suppression refreshes and cleans up any clock signal, and provides it as
reference clock at the two outputs.

The WCM is connected via one cable to the HDSP 9632, making it already fully operational.
The drivers of the HDSP 9632 include support for the WCM.

Thanks to several LEDs (power, termination, LOCK) and the highly integrated concept of instal­lation, first operation and usage are simple even for the inexperienced user.
