a. No longer available. Production of this board ended in 2004.
b. On the TaitNet Ethernet system interface board, some pins on the system interface connector can be configured to
provide different signals (selectable by switch). For more details refer to Application Note TN-1142-AN.
c. The unbalanced input on these boards was changed from AC to DC coupled in August 2005. This change was
made for paging, and the version of these boards was changed from 0 to 1. To check the version of a system
interface board, run the Service Kit and select Monitor > Module Details > Reciter. In the Versions area, the Sys-
tem Interface field displays the version number.
d. On version 1 and later system interface boards, digital inputs 3, 4, 5, and 6 may also be configured as outputs using
a Task Manager statement. For more details refer to the "Connection" chapter in the Installation and Operation
Manual, and to the Service Kit documentation.
e. On the TaitNet Ethernet system interface board, digital inputs 1, 2, 3, and 4 may also be configured as outputs
using a Task Manager statement. For more details refer to the "Connection" chapter in the Installation and Oper-
ation Manual, the Service Kit documentation, and to Application Note TN-1142-AN.
