Section 9 – Synchronization with other DTRS units06/97 – 1.00 – 9-19 – Synchronization with otherDTRS unitsThis section describes the techniques and methodsto be followed when the DA-98 is linked to otherDTRS units (e.g. TASCAM DA-38, DA-88 and ofcourse other DA-98 units).Up to 16 DTRS units can be linked, for a total of128 digital tracks.If you are connecting DTRS units of differenttypes to the DA-98, use the DA-98 as the masterunit and the other units as slave units.9.1 SynchronizationconnectionsAs described in 4.4.1, “Multiple DTRS units”, thecable to be used when connecting the DA-98 toother DTRS units for synchronization purposesshould be a PW-88S cable. This is 1 meter (3 ft.)long. If you require a longer cable, please consultyour TASCAM dealer.The synchronization connections form a “daisy-chain”, with the master unit at the head of thechain, and the last slave at the tail.Connections are made from the SYNC OUT [44] ofone unit to the REMOTE IN/SYNC IN [43] of thenext.You do not need to change the CLOCK settingfrom INT [30] or to connect the WORD SYNCconnectors [39].9.2 Machine ID and master/slave settingsEach DTRS unit in the chain must be assigned amachine ID. The unit at the head of the chain (themaster) should have ID number 1.Though not strictly necessary, we suggest, thatIDs are assigned in a consecutive sequential orderfrom the head of the chain.9.2.1 Differences between DTRS modelsThe DA-98 and DA-38 both use machine IDs thatare set by software (the machine must be turnedon for the ID to be set). The values for the IDs ofthese models start at “1” and go up to “16”.The switch on the back of the DA-88 is only oper-ative when the unit is turned off. It is marked from“0” through “F”.When including DA-88s and DA-98s in the samechain, add 1 to the number shown on the DA-88’srear panel machine ID switch to make the DA-88’s machine ID match the series of the DA-98(and DA-38) IDs. Any DA-88 whose Machine IDis not 1 (the switch has been set to a value otherthan 0) will show its Slave ID briefly at power-on.Therefore, for a chain of three units; a DA-98 asmaster, with a DA-88 and DA-38 as slaves, themachines’ IDs should be set as follows:WARNINGS• Be sure to use only the optional PW-88S sync cables.The use of any other cables could damage the DA-98.• Be sure to connect the termination plug that comes withthe PW-88S cable to the last slave’s SYNC OUT con-nector [44], or else incorrect functions may occur.• Turn on all the DTRS units in your system, regardless ofwhether you actually use all of them. A unit or unitsturned off will make synchronization impossible.• To synchronize multiple DTRS units, use a pre-format-ted tape in the master unit, and also in the slave units.Since the DTRS system uses ABS time to achieve syn-chronization, tapes without ABS time recorded on themmake synchronization impossible.• To synchronize multiple DTRS units, all the tapes ineach unit must be formatted at the same sampling rate,or synchronization is impossible.WARNINGAlways make and break all synchronization connectionswith the power to all units in the chain turned OFF.Unit How the ID issetDA-98 1 1 Menu system (seebelow)ONDA-88 1 2 Rotary switch onrear panelOFF
