INSTALLING THE IVP4 BOARDS
There are two parts to this procedure:
•
Setting SW1.1 and SW12.1
•
Inserting the IVP4 boards into the AUDIX Voice Power computer
Setting SW1.1 and SW12.1
NOTE
The AUDIX Voice Power R3.0 system supports up to three IVP4 boards. In this procedure,
the IVP4 boards (also referred to as "cards") are numbered 0 through 2.
Before you install the IVP4 boards you must set the termination impedance (SW1.1) and I/O address
switches (SW12.1) on each board. The location of the switches is shown in Figure 3-4.
