SECTION 3 – ISP-100 DSP ARCHITECTURE
___________________________________
ISP-100 Input/Output Capabilities
As mentioned previously, one of the most impressive and unique features of the
ISP-100 is the configurable input/output (I/O). This feature allows the designer or
installer to select between analog input or output modules, and/or digital
input/output combination modules to accommodate specific application needs
without having to pay for unused I/O. These modules are two channel units and
can be intermixed between analog and digital, providing a variety of I/O
combinations. When using analog modules, the ISP-100 supports a maximum of
4 inputs (MIM modules), with a maximum of eight outputs (MOM modules), thus
offering combinations like 2x2, 2x4, 2x6, 2x8, 4x4, and 4x6. If an MDM-1 digital
module is installed in slot 2, a 4x8 I/O configuration can be achieved.
Here is a look at the I/O module bays of the ISP-100. It will be helpful to have a
“mental picture” of the I/O structure of the ISP-100 when designing systems in

INPUTS/OUTPUTS
Figure 1.
SLOT 1 – Input only (MIM or MDM)
SLOT 2 – Input and/or Output (MIM, MOM, or MDM)
SLOT 3 – Output Only (MOM or MDM)
SLOT 4 – Output Only (MOM or MDM)
SLOT 5 – Output Only (MOM or MDM)
ANALOG AND DIGITAL I/O SLOT CONFIGURATIONS:
2 X 2 Input= SLOT 1 Output= SLOT 5. 2 X 4 Input= SLOT1 Output= SLOT 3, 5.
2 X 6 Input= SLOT 1 Output= SLOTS 3, 4, 5. 2 X 8 Input= SLOT1 Output= SLOTS 2, 3, 4, 5.
4 X 6 Input= SLOTS 1,2 Output= SLOTS 3,4,5.
DIGITAL I/O CARD – SLOT 2 CONFIGURATION:
4 X 8 Input= SLOTS 1,2* Output= SLOTS 3,4,5.
*MDM-1 DIGITAL CARD
Understanding this I/O structure will also be helpful when specifying or ordering
ISP-100 hardware.
