Hey I am hooking up 2 da7's with tandem cards in slot 3, adat cards in 1/2 on slave board on the master board i have adat card in 1 and ad/da in 2, in the d i/o window both the tandem cards show crosshatched all though it appears the both boards see them, it also shows the adda card being crosshatched, what am I doing wrong .Thanks

Pete, In addition to the Tandem cable you'll need to use either a serial cable (apple imagewriter 2) from the ToPC on both consoles or MIDI cables both in and out to complete the communications from the master to slave console. Sometimes resetting the consoles and re-configuring them for tandem clears any errors.

Pete, I found this document on the message board. If your trying to run MAX you will need to use MIDI as the connection between the two consoles.

1)Make all connections with both of the mixers OFF. You will need: (2)WR_TNDM cards, (1)DA/DB-DB Tandem Cable, (1) MINI DIN 8-Pin Serial Cable (Macintosh Printer Cable), (1) DA/BNC 75W BNC-BNC wordclock cable.

2)Panasonic Pro Audio TANDEM cable MUST be used (Part No. DA/DB-DB). Set one of the TANDEM cards to MASTER and the other TANDEM card to SLAVE. Insert TANDEM cards in console and connect the TANDEM cable. Make sure ALL cards and cables are secured with the supplied mounting screws for proper grounding.

3)Connection MUST be made between the consoles via the MIDI or TO PC Ports (TO PC recommended. MIDI is slower). The PC cable is a standard Mini DIN 8-Pin Serial cable (Macintosh printer cable). The following procedures shall document usage with the TO PC port.

4)Worclock MUST be connected between the consoles. In a stand alone system, with no outside clock source, using a 75W BNC-BNC cable (DA/BNC), connect WORDCLOCK OUT of the MASTER DA7 to WORDCLOCK IN of the SLAVE DA7.

Make sure the WORDCLOCK TERMINATION switch on the MASTER is set to OFF. The termination switch on the SLAVE should be set to ON or TERMINATE. If using an outside source as Master Wordclock, connect the WORD CLOCK OUT of the generator to WORDCLOCK IN on the MASTER DA7, WORDCLOCK OUT on the MASTER DA7 to WORDCLOCK IN on the SLAVE DA7. Make sure the termination switch on the MASTER is set to OFF. The termination switch on the SLAVE should be set to ON or TERMINATE.

If you are using a distributed clock system, connect WORDCLOCK OUT of the generator to WORDCLOCK IN on the MASTER DA7 and WORDCLOCK IN on the slave DA7 as well. Termination is ON for both DA7’s.

SETTINGS

5)Turn both consoles on at this time. TANDEM operation should take place from a normal POWER ON. However, it is recommended that a MASTER RESET be performed. BACKUP internal data if necessary through a MIDI BULK DUMP. MASTER RESET each console individually (turn power on holding down CHANNEL and METER buttons in the MASTER DISPLAY on the front panel of the DA7, WAIT for FLIP lights to come on, then release buttons, WAIT for the CHANNEL screen to come up before making changes).

6)MASTER RESET clears fader calibration data. Execute FADER CALIBRATION by pressing the FADER LAYER 1-16 button and the CUSTOM MIDI button on the front panel.

7)Go to the MIDI SET UP screen. Under PORT SELECT in the SERIAL I/O SETUP section, make sure TO PC is selected (reverse video or darkened). Set BAUD RATE for both consoles to 125K by highlighting the rate with the curser and using the parameter dial to make the changes. Under MIDI SETUP, make sure MIDI channels are set to the SAME channels for Gen. Rx/Ge. Tx and set the SAME for BOTH consoles. Set Gen Rx/Gen Tx PORT to TO PC.

8)Go to the D I/O TO SLOT screen. Slot 3 will automatically see the Tandem Card. If TANDEM is not selected in the NORMAL/INS/TANDEM area, select it. Below the “SLOT 3 TANDEM” area, make sure TANDEM is set to ON. Select AUTO in the OFFSET DELAY section. Make sure the PORT SELECT is set to TO PC. CONNECT will read SLOT NG or DATA NG until SLAVE console is configured.

9)Go to step 6 and repeat procedures 6-8 on the slave console. Once again, CONNECT will read SLOT NG or DATA NG until some form of data is sent between the consoles. Turning a channel to ON will initiate data flow, and the CONNECT prompt in the D I/O TO SLOT screen will then read OK on both DA7’s (this can take up to 5 seconds).

10)REMEMBER: A distributed master wordclock is highly recommended in a multiclock system (ie: ADAT w/BRC and ProTools, etc.)

Thanks all you guys rock!!!! Thanks to carl as well.
