18.7 Firmware
The DMC-842 is internally based on programmable logic. By re-programming of a little compo-
nent called Flash-PROM, both function and behavior of the unit can be changed at any time.
At the time of writing this manual the unit is shipped with firmware version 2.10. The firmware
version is displayed after power on for about one second on the Gain displays of the DMC-842.
The current version of firmware and remote software support the AES42 standard revision of
2006.
The I64 MADI Card has its own firmware. I64 MADI Cards with the latest firmware have a
sticker with the firmware version date code on them (20070217). The firmware of the I64 MADI
Card can be updated in the factory. Please contact the RME support or your local dealer.

GND is connected to pins 2, 5, 8, 11, 16, 19, 22, 25. Pin 13 is not connected.
The Yamaha pinout is quite popular as well. When building a D-sub to D-sub adapter or con-
nection cable, please make sure that the connectors are clearly labeled with Tascam and Ya-
maha. The cable can only be used when the Tascam side is connected to a Tascam connector,
and the Yamaha side is connected to a Yamaha connector.
