1. Introduction 
Thank you for choosing the TCO. The Time Code Option provides synchronisation to SMPTE 
and video in professional studio quality. SteadyClock ensures that the word clock derived from 
the input signals is of low jitter and therefore highly compatible. The TCO supports all standard 
formats and conversions of these, turning it into a highly useful tool within the studio environ-
ment.

5. Installing the TCO-HDSP 
Before installing the TCO card, please make sure the computer is switched off and the 
power cable is disconnected from the mains supply. 
1.  Disconnect the power cord and all other cables from the computer. 
2.  Remove the computer's housing. Further information on how to do this can be obtained 
from your computer’s instruction manual. 
3.  Before removing the TCO from its protective bag: discharge any static in your body by 
touching the metal chassis of the PC. 
4.  Connect the TCO with the PCI card using the supplied flat ribbon cable. For this, plug one 
end of the cable into the matching connector of the PCI card. On the AES-32 the connector 
is labelled Synchronizer Board, on other cards the TCO replaces the Word Clock Module. 
Plug the other end into the connector X101 on the TCO. 
5.  Insert the TCO into a free PCI slot and fasten the screw. The TCO needs no slot on the 
motherboard, but includes a stabilizing edge, which fits in both PCI and ISA slots. 
6.  Insert the PCI card firmly into a free PCI slot, press and fasten the screw. 
7.  Replace the computer's housing. 
8.  Reconnect all cables including the power cord. 
6. Installing the TCO-FF 
To install the TCO the Fireface 800 must be opened. If you feel unsecure to do so please con-
sult a technician and let him do this. Else please follow the instructions below step by step. 
Before installing the TCO, please make sure the Fireface 800 is switched off and the power 
cable is disconnected from the mains supply. 
1. Disconnect the power cord and all other cables from the Fireface 800. 
2. Loosen and remove both rack ears (two screws each). 
3. Use a screwdriver (Phillips 1) to remove the 3 screws on the cover near the back panel, and 
2 screws on each side of the Fireface 800, so that the cover can be taken off by sliding it to the 
rear. 
4. Remove the TCO spare plate within the rear panel (2 screws). 
5. Before removing the TCO from its protective bag, discharge any static in your body by touch-
ing the metal chassis of the Fireface. 
6. Slide the TCO into the rear panel's hole from the inside. Watch the correct position, so that 
both screws found in the PCB of the TCO do not press on the TRS jacks, but are placed in-
between those. 
7. Fasten the TCO with the two black self-tapping screws from the TCO screw set. Do not use 
the screws of the spare plate, as these are thread screws. 

 User’s Guide TCO 6
8. Fold the ribbon cable one time and plug it into socket X1105 on the motherboard, see picture 
below. 
Now you are ready to re-assemble the Fireface. 
9. Check that the safety-earth wire (yellow–green) is still connected to the cover. Then put the 
cover on and slide it into the aluminum front panel of the Fireface 800. 
10. Fasten the 3 screws on the cover and the two screws on each side of the Fireface 800. 
11. Attach and fasten the rack ears. Finished!

7. Operation and Usage 
7.1 TCO-FF 
After installation of the TCO the Fireface 800 has to be updated to the latest driver and firmware 
versions, found on the website www.rme-audio.com in the section Download. 
After reboot the Settings dialog includes an additional page labelled TCO, and on the main 
page the new sync-option TCO can be selected. 
For synchronization to a video or LTC signal choose Clock Mode AutoSync and TCO as Pre-
ferred Sync Ref on the main page of the settings dialog. All further settings are done on the 
TCO page. 
LTC In: The time values read from the LTC signal. These values are passed on to the applica-
tion unchanged. 
Input State: An LTC input signal detected as valid (valid) is followed by the display of the num-
ber of frames per second, and whether this is Full Frame or Drop Frame code. A valid video 
signal is shown as PAL or NTSC. An incoming word clock signal is analyzed and displayed to 
be in the Single Speed, Double Speed or Quad Speed range. 
Sync Source: Input select switch for the 
inputs LTC and video. Lock is displayed as 
soon as the TCO is able to synchronize on an 
input signal. 
Video Input: The BNC input can be 
terminated with 75 Ohms. 
Frame Rate: The frame rate of the incoming 
SMPTE signal must always be defined 
manually. 
Sample Rate: The TCO derives a word clock 
of 44.1 kHz or 48 kHz from the sync-signal. 
With the setting 'from App' chosen the value 
sent from the ASIO application to the driver is 
used. 
The lower field provides common Pull-Up and 
Pull-Down values. The final value of the 
previously defined sample rate is shown in the 
field  Frequency, in case the sync-signal is 
valid. 
Frequency: The TCO measures the word 
clock that it generates and shows the current 
value in this field. 
MIDI Input: The Fireface's MIDI input includes either the MTC signal of the TCO, or the MIDI 
data of the 5-pin DIN input (External).

7.2 TCO-HDSP 
After installation of the TCO-HDSP update to the latest driver and firmware version, found on 
the website www.rme-audio.com in the section Download. 
After a reboot the Settings dialog includes an additional page labelled TCO, and on the main 
page the new sync-option TCO can be selected. 
For synchronization to a video or LTC signal choose Clock Mode AutoSync and TCO as Pre-
ferred Sync Ref on the main page of the settings dialog. 
All further settings are then done on the TCO page. 
LTC In: The time values read from the LTC signal. These values are passed on to the applica-
tion unchanged. 
Input State: An LTC input signal detected as valid (valid) is followed by the display of the num-
ber of frames per second, and whether this is Full Frame or Drop Frame code. 23.976 is de-
tected as 24, 29.97 as 30. A valid video signal is shown as PAL or NTSC. An incoming word 
clock signal is analyzed and displayed to be in the Single Speed, Double Speed or Quad Speed 
range. 
Sync Source: Input select switch for the 
inputs LTC, video and word clock. Lock is 
displayed as soon as the TCO is able to 
synchronize on an input signal. Also at 
the bracket the green LED will light up 
then. 
Video / Word Input: The BNC input can 
be terminated with 75 Ohms. At the 
bracket the yellow LED will light up with 
termination activated. 
WCK Conversion: Default setting is 1:1. 
This very special option allows for a 
synchronous conversion of the word clock 
input signal. 44.1 kHz will turn into 48 
kHz, where the 48 kHz are not free 
running, but have a synchronous 
relationship to the original clock. The 
same is available for converting 48 kHz to 
44.1 kHz. 
Frame Rate: The frame rate of the 
incoming SMPTE signal must always be 
defined manually, as it is not detected 
automatically from the input signal. 

 User’s Guide TCO 9
Sample Rate: The TCO derives a word clock of 44.1 kHz or 48 kHz from the synchronization 
signal. With the setting 'from App' active the value sent from the ASIO application to the driver is 
used. 
The lower field provides common Pull-Up and Pull-Down values. The final value of the previ-
ously defined sample rate is shown in the field Frequency in case the sync-signal is valid. 
Frequency: The TCO measures the word clock that it generates and shows the current value in 
this field. 
Note: The MTC signal is provided via a new (virtual) MIDI input port. This one has to be chosen 
as MTC sync source within the application. 
7.3 Updated Information on the TCO - HDSP 
The latest Windows HDSP(e) drivers 4.06 added several new features to the HDSP TCO: 
•  Direct support for 23.976 (23.98) fps (HD) 
•  23.976 fps can also be used with external word clock 
•  Support for Double Speed with ASIO. When using an ASIO application in 88.2 or 96 kHz this 
frequency will be shown in the Frequency display, although only 44.1 or 48 kHz are present 
as external reference. The APP timecode derived from the LTC signal will be automatically 
adjusted. 
The LTC output of the TCO has the following peculiarities: 
•  The output of timecode requires an ASIO program that supports this feature. Although this 
function is part of the ASIO specifikation, most popular programs do not support it. 
•  The output signal of the TCO can not be switched off. In Stop mode the same timecode sig-
nal is sent repeatedly (Positional Timecode), which equals a stop. 
7.4 Notes on using the HDSPe PCI 
Since driver version 3.068 the TCO can also be used with the HDSPe PCI, and therefore with 
Multiface and Digiface. The following notes and limitations apply: 
•  Only ASIO timecode (APP) is supported. Converting LTC to MTC is not supported. 
•  Generating an audio clock out of the incoming timecode requires a BNC cable from the 
TCO's word clock output to the word clock input of the Multiface/Digiface. In the Settings dia-
log Pref. Sync Ref has to be set to TCO and Clock Mode must be set to AutoSync. If the in-
coming timecode is not used to clock the HDSP system the BNC cable is not required. 
•  The PCI Express Bus provides only 12 Volt and a limited amount of current. Therefore ini-
tially the HDSP TCO will not receive any operating voltage (5 Volt) from the HDSPe PCI. For 
the HDSP TCO to receive its operating voltage via the flat ribbon cable from the HDSP PCIe 
card, connect the computer’s floppy power supply output to the 4-pin connector found on the 
HDSPe PCI.
