INTRODUCTION TO THE HURON
New Huron cards and modules can be purchased to expand the
capability of Huron. Qualified service personnel should
perform the installation of these cards or modules.
These guidelines should be followed when installing new cards:
Addition and removal of all cards should only be attempted
when the power to the Huron system is off. When installing a
Huron ADAT I/O card, this should be installed in slot 0 (the
leftmost slot when viewing the Huron from the front). When
installing a new DSP or I/O carrier card, install it in the slot
directly next to the last Huron DSP or I/O card. There should
be no vacant slots between Huron DSP and I/O cards.
Addition and removal of all modules should only be attempted
when the power to the Huron system is off. When installing
new I/O modules onto a Huron I/O carrier card, the position and
orientation of the modules is very important. Input modules are
always populated in module 8 first, followed by module 7, and
so on. Output modules are always populated in module 1 first,
followed by module 2, and so on. When inserting a new input
module insert it in the highest available slot number. When
inserting a new output module, insert it in the lowest available
slot number. Always be careful to ensure the correct orientation
of any modules. The orientation shown in Figure 4 must be
adhered to for all modules. Special attention must also be paid
to ensuring the module connector pins mate perfectly with the
I/O base card connectors. Incorrect insertion of the modules
could result in damage to the module and/or the workstation.
