NOTE

When you set the machine IDs, you can set the ID of any machine first, but we recommend doing this in a standard sequence, working from the head of the chain to the tail.

3.2 Connections (parallel units)

The RC-898 allows transport control of a unit con- nected to the EXT 1 parallel port. Before making this connection, check the specifications of the other unit to ensure that the control pins available match those provided by the RC-898, as shown below in 3.2.2, “Parallel control/GPI pinout”.

NOTE

The RC-898 provides only transport control for a unit con- nected to the parallel port. Functions such as track arming, etc. are not possible when using the EXT 1 parallel port.

If a passive unit that does not supply power to the tally supply pin (8) is being used, switch 1 (TALLY POWER) of the RC-898 [45] must be set on (down) to allow the RC-898 to provide this power.

3.2.1 Connections (GPI event units)

The EXT 1 parallel port may also be used for the purpose of controlling up to five GPI event-con- trolled devices.

The way in which these devices may be triggered from the RC-898 is explained in 9.2, “Controlling GPI devices”.

3.2.2 Parallel control/GPI pinout

The following table gives the pin assignments for the parallel/GPI connector (EXT 1). GPI connec- tions are shown in square brackets:

1STOP/[Event 1]

3.3Connections (RS-422

units)

The RC-898 allows control of a unit implementing the Sony P2 protocol. This connection is made through the EXT 2 serial port [43], using a serial cable designed for this purpose. The pinout for this connector is as follows:

1Shield

2RX+

3TX–

4GND

5—

6GND

7RX–

8TX+

9Shield

Make the connection using a cable designed for RS-422 connection (check the pinout of your P2 device before making the connection). This machine may now be controlled by the RC-898 when the E2 MACHINE indicator [8] is lit.

3.4 A note on system clocks

When working with many digital audio units, all these units must be fed from the same clock source (either word or video). If this is not done, there is a risk that speakers, etc. may be damaged.

Note that this clock master is entirely different from the timecode master in a studio setup. It is perfectly possible for a clock slave to be a time- code master and vice versa.
