ICB/MCA Connections – Model 556/556A AIM
A 34-pin rear panel Data connector and 20-pin ICB connector provide all the neces-
sary signals for interfacing to the Model 556/556A AIM MCA. For a detailed descrip-
tion, see Appendix C, MCA and ICB Interface Connectors.
Note
556 AIM modules manufactured prior to April of 1992 may
exhibit a problem and require a rework. The problem
symptom is an 8k spectral shift or digital offset. If you ex-
perience this problem, or have a 556 AIM manufactured
prior to April of 1992, please contact the Customer Service
Department in Meriden, Connecticut at (800) 225 - 6370.
• Connect the C-1703-2 MCA interface cable between the data connector on the
9660’s rear panel and the Model 556/556A AIM module.
• Connect the Model C-1560 12-port ICB Connecting Cable between the ICB
connectors on the rear panels of the Models 9660 ICB DSP and 556/556A AIM
modules.
Initialization and Self-Diagnostics
When power is first applied to the Model 9660, it will go through an initialization and
self diagnostics process. The BDC Busy LED on the front panel will blink for duration
of the process, which requires 15 to 20 seconds to complete. The Ready LED normally
remains off during the power-up process.
If the self diagnostics were successful and communication is established with the
Model 556/566A AIM, the BDC Busy LED will turn off and the Ready LED will re-
main off.
If the Model 9660 detected a hardware error during the initialization process, the
Ready LED (lit yellow) will go on continuously and remain on. This could result from
a fault in the 9660 module or a faulty or unconnected ICB cable. Please consult the
factory if necessary.
When a device has been selected through the application software, the Ready LED (lit
green) will be on continuously, indicating that communications between the host com-
puter and the Model 9660 has been established.
