Connector Details
Connector P8 contains the input connections for sense inputs 1 and 2. Connector P7
contains the connections for sense inputs 3 and 4. These sense inputs are individually
opto-isolated. They may be configured with jumpers to detect either contact closures or
voltage levels. The polarity of the active signal sent to the FSA Server can be individually
selected with the FSA Maintenance Utility. The pin connections for these connectors are
as follows:
Pin 1 (GND) = Connected to Model 6203 chassis ground
Pin 2 Input (-) = This is the negative input for Sense 1 (or 3)
Pin 3 Input (+) = This is the positive input for Sense 1 (or 3)
Pin 4 (GND)
= Connected to Model 6203 chassis ground
Pin 5 Input (-) = This is the negative input for Sense 2 (or 4)
Pin 6 Input (+) = This is the positive input for Sense 2 (or 4)
The jumpers JP1 through JP 4 are used to apply +12 Vdc to the positive side of each sense
input through a 1.5 k
Ω pull-up resistor. See Power Supply Board Jumpers on page 164 for
more information on these jumpers.
IP Interface Board Connectors
The Station Transponder Unit Interface board performs two important functions in the
Station Transponder Unit. In every unit, it handles the translation of TCP/IP data packets
from the FSA Server into RS-232 serial format to pass to the serial port at J6 on the
Transponder board. When the Model 6203 sends information back to the FSA Server it
handles the process in reverse. If a VoIP Intercom board is installed in the Station
Transponder Unit, the IP Interface board provides the connections for the VoIP Intercom
to pass its audio and control signals on to the Transponder board.
If there is no VoIP Intercom installed, then the IP network connection is made by plugging
the network cable directly into the RJ-45 connector that is part of U1 on the IP Interface
board.
If there is a VoIP Intercom board installed, then the IP network connection is made to an
RJ-45 jack on the VoIP board, with the other RJ-45 jack used to connect with U1. See
Figure 52 and Figure 53 .
