Section 9 – Synchronization with other DTRS units

9 – Synchronization with other DTRS units

This section describes the techniques and methods to be followed when the DA-98 is linked to other DTRS units (e.g. TASCAM DA-38, DA-88 and of course other DA-98 units).

Up to 16 DTRS units can be linked, for a total of 128 digital tracks.

If you are connecting DTRS units of different types to the DA-98, use the DA-98 as the master unit and the other units as slave units.

9.1Synchronization connections

from INT [30] or to connect the WORD SYNC connectors [39].

WARNING

Always make and break all synchronization connections with the power to all units in the chain turned OFF.

9.2 Machine ID and master/ slave settings

Each DTRS unit in the chain must be assigned a machine ID. The unit at the head of the chain (the master) should have ID number 1.

Though not strictly necessary, we suggest, that IDs are assigned in a consecutive sequential order from the head of the chain.

As described in 4.4.1, “Multiple DTRS units”, the cable to be used when connecting the DA-98 to other DTRS units for synchronization purposes should be a PW-88S cable. This is 1 meter (3 ft.) long. If you require a longer cable, please consult your TASCAM dealer.

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 with the 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 of whether you actually use all of them. A unit or units turned 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 them make synchronization impossible.

•To synchronize multiple DTRS units, all the tapes in each unit must be formatted at the same sampling rate, or synchronization is impossible.

The synchronization connections form a “daisy- chain”, with the master unit at the head of the chain, and the last slave at the tail.

Connections are made from the SYNC OUT [44] of

one unit to the[43] of the next.

You do not need to change the CLOCK setting

9.2.1 Differences between DTRS models

The DA-98 and DA-38 both use machine IDs that are set by software (the machine must be turned on for the ID to be set). The values for the IDs of these 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 same chain, add 1 to the number shown on the DA-88’s rear 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 ID is not 1 (the switch has been set to a value other than 0) will show its Slave ID briefly at power-on.

Therefore, for a chain of three units; a DA-98 as master, with a DA-88 and DA-38 as slaves, the machines’ IDs should be set as follows:

Unit			How the ID is
			set
DA-98	1	1	Menu system (see	ON
			below)
DA-88	1	2	Rotary switch on	OFF
			rear panel
