Control Wires
In this configuration, ap12VDC to the control wires (using
customer supplied switches) will have the following results:
Control Wire #1 =
Outlets 1 & 3 enabled
Control Wire #2 =
Outlet 2 enabled
Control Wire #3 =
Outlet 4 enabled
Control Wire #4 =

Mode 4: S.C. (Serial Communication) Mode
NOTE:
When the ISP74 is configured for S.C. mode, it is
important to understand that the connections and operational
procedures used are quite different from any of the other modes.
In S.C. mode, Comet Flash is the only available pattern.
Dip Switches
S.C. emulation is accomplished by placing Dip Switch 5 in the ON
position. At this point, the remaining Dip Switches (1 thru 4) are
used to configure the address of the ISP74 for use in a S.C.
system. The addressing properties function as follows:

Control Wires
In this configuration, control wires 1, 2 , 3 & 4 are not used to
enable outlets or control Hi/Lo power activation, as with the
previous modes. Outlet control and Hi/Lo power activation is
handled by the S.C. Multi-Purpose Controller.
Section 3: Hi/Lo Power
Hi/Lo power activation and functionality can be configured in any
of 4 available modes, depending upon how Dip Switches 3 & 4
are positioned. Table 2 on Page 4 outlines each of the 4
configurations and their attributes.
NOTE:
In S.C. emulation
mode, Hi/Lo power activation is controlled with an S.C. Multi-
Purpose Controller.
Section 4: Flash Patterns
The ISP74 can generate up to 16 flash patterns by activating the 4
Pattern Control wires, either individually or in combination.
NOTE:
in S.C. mode, Comet Flash is the only available pattern. Table 1
on page 4 outlines all of the available patterns and the wire
activations needed to produce them.
Section 5: Diagnostix™ (Optional)
The optional Diagnostix™ display allows the operator to confirm
proper operation of not only the 4 outlets on the ISP74, but of the
strobe light and strobe cable connected to these outlets as well.
Each LED indicator on the Diagnostix™ display, provides
diagnostic information for one outlet. For example; LED #1
monitors Outlet #1, etc. The LED’s appearance indicates the
condition of it’s corresponding outlet. Refer to Table 3 on Page 4.
