Troubleshooting
This section describes some basic troubleshooting techniques for the serial/Ethernet transla-
tion units and the Serial Hall Call Driver Assembly (SC-HCDA).
Serial/Ethernet Translation
The serial I/O protocol used for MCE serial hall call and serial I/O board connections is trans-
lated to and from Ethernet bus protocol for system level communication over the iControl Sys-
tem network by the SC-HCE board. (System hub/switch in iCentral dispatcher. Orange TCP/IP
cables.)
SC-HCE Assemblies
The SC-HCE-2 is the newest release assembly. Older systems may use the SC-HCE-ME board
(not pictured). The SC-HCE-2 assembly is shown in the illustration below.
After making changes to SC-HCE-2 board configuration, reset the iCue PC so that it can rebuild
internal communication tables.
