OnAir 2000M2 Digital Mixing Console
15-22 HW Modules SW V 4.0 Date printed: 12.11.03
15.17 Time Sync Module 1.942.150.xx (Option)
With a time sync module, the console's internal clock can be synchronized
to an external time reference unit, such as a DCF77 or GPS receiver, or a
Mobatime clock providing a serial output signal. The current software of
the module supports AFNOR and Seiko protocols as well as SMPTE bi-
phase timecode (Leitch).
For either of these time reference units (except AFNOR and SMPTE) the
connector labeled RS232 is used. For ANOR and SMPTE signals, a trans-
former-balanced input is available on the RS422 connector. Please note the
configuration (chapter 12.2.5) and the DIP switch and jumper setting
(chapter 16.10), depending on the type of reference unit being used.
Note: The Time Sync Module software version is completely independent of the
console software; this means that a Time Sync Module with the most re-
cent software version supports all time sources available, even if installed
in a console with the earliest software version.
Pin Assignments: RS422 (D-type, 9 pin, male):
Pin Signal Pin Signal
1 GND 6 SMPTE/AFNOR –
2 RX + (unit to console) 7 RX – (PC to console)
3 TX – (console to unit) 8 TX + (console to PC)
4 SMPTE/AFNOR + 9 GND
5 GND TX: transmit; RX: receive
RS232 (D-type, 9 pin, male):
Pin Signal Pin Signal
1 +12 V (Note 1) 6 +12 V (Note 1)
2 RX (unit to console) 7 –12 V (Note 1)
3 TX (console to unit) 8 –12 V (Note 1)
4 +12 V (Note 1) 9 n.c.
5 GND TX: transmit; RX: receive
Note 1: These voltages are available if jumpers 12-13 and 10-11 are inserted. These
outputs are very high-Z and must not be used, except for the specified DCF77 and MOBA
receivers only!
