In addition to Fast Perfusion Change using analog outputs to control perfusion changes DURING a
sweep, Fast Perfusion can also use 4 bits of high speed digital output from Port 0 (Fig. 10.3.1.2.5). In the
Sweep Stimulation section showing the IC0 or IC1 ‘Digital D3 <- D0’ section (lower left panel), the
channels are selected by putting in DigitalOutput bits 0 to 3 (ie Digital 3 <- 0). Note that either the digital
outputs can be set from IC0 or IC1.
Fig. 10.3.1.2.5. An example of Fast Perfusion change DURING a sweep for controlling 15 channels using
one BioScience Tools controller and 4 bits from the high speed digital out Port 0 where if all the bits are
off, all channels are off. After 400 msec, the digital output is switched from 0001 ( = 1 = bit 1 on =
Channel 1) to 0010 ( = 2 = bit 2 on = Channel 2).for 1000 msec producing a 1000 msec Channel 2 pulse.
Table 10.3.1.2.2 shows show to set DigitalOut bits 3 to 0 in binary to turn on a perfusion channel for the
BioScience Tools PC-16 controller. Only one perfusion channel can be on at any one time, and all bits off
means that no channels are on, and all bits on turns on Ch 15. Channel 16 on the BioScience Tools
controller has to be turned on manually.

Table 10.3.1.2.2. Setting the DigitalOut bits 3 to 0 in binary to turn on Ch1 to 15 on the BioScence Tools
PC-16 controller. When DigitalOut bits 3 <- 0 equals ‘0000’, then all channels are off.
To implement 4 bit DigitalOut control of the AutoMate Scientific ValveLink 8.2 in which DigitalOut bits 3 <-
0 = ‘0000’ means Ch 1 on, ‘1111’ means Ch 16 on (Table 10.3.1.2.3). Turning all channels in the
Automate controller off has to be done manually.
