instruments to other masters. In either case, the expansion cable is connected in the same way; from the EXPANSION
OUT port to the EXPANSION IN port of the next instrument, moving in a direction away from the PC.
When using several instruments in a master/slave configuration, label the instruments to avoid confusion. Using the
same example as above, say you have a DI-510-64 (64 input portable instrument) and a DI-510-64-X (64 input porta-
ble expansion unit) multiplexed together and want to record the signal connected to channel 28. Looking at the instru-
ments, there are four groups or “banks” of 32 inputs, each bank consisting of channels 1 through 32 (128 total inputs).
Since there are a total of four channels labeled 28, how will you know which one will be recorded? A small box is
provided on the instrument panel to label banks of channels and avoid this problem. In order for you and the software
(either W
IN
D
AQ
or the ActiveX Control Library) to tell these inputs apart, label each bank of 32 inputs with a letter
according to the following table (an ordinary pencil is sufficient):
For example, in the previous 128-channel example, the 64 master instrument channels now become channels A1
through A32 and B1 through B32 and the 64 slave instrument channels now become channels C1 through C32 and
D1 through D32. The “channel 28” ambiguity disappears, the channel in question is either channel A28, B28, C28 or
D28.
If you are using this instrument as the
MASTER instrument: …then write this letter in the box on the slave instrument(s) overlay for:
the first 32 channels the next 32 channels the next 32 channels...
