4.4. DATA LOADING.
Explanations of data loading the ECU and the TSS-4100 follow.
4.4.1. E
CU Data.
The External Compensation Unit (ECU) attached to the TSS-4100 holds two sets of data. The first set of data, the TSS ECU Media
Set Builder, contains the aircraft-configuration strapping for the TSS. These straps are detailed in Table 2-2. Thes e data must be data
loaded through the TSS-4100. Refer to Table 4-1 for the data load busses and pins. The TSS-4100 will recognize the format of the
data set and store the data appropriately. The second set of data contains the aircraft Mode S Address. The TSS Mode S Address
Programming Tool loads just the Mode S address onto the ECU, refer to P aragraph 4.5 for details. Verification of a proper load of
these sets of data w ill be accomplished by reviewing the TSS-4100 Electronic Nameplate on the air craft m aintenance system. See
Paragraph 4.4.3 for more information on the TSS electronic nameplate.
Table 4-1. Data Load Buses And Pins
Bus Name Pin Numbers (Hi & Low) Bus Sp eed
Control B Input Bus LMP-7D & 7C Low
Dataload Input Bus LMP-7J & 7K High
TSS-1 Output Bus LMP-7A & 7B Low
TSS-2 Output Bus LMP-1A & 1B High
TSS-3 Output Bus RMP-1A & 1B High
4.4.1.1. If the bus speeds are configured differently in the E CU than what is listed in Ta ble 4-1, follow the follo wing s teps in order
to load data.
a. Disconnect the cable from the ECU.
b. Power cycle the TSS-4100. This forces t he TSS to use the default speeds listed in Table 4-1.
c. R econnect the cable to the ECU.
d. Start the data load process as normal. The d ata l oad software always uses the default bus speeds. The bus speeds in the ECU
are ignored once the data load process has begun.
4.4.2. T
SS Data Loading.
The TSSA-4100 and the ECU files are field loadable. Rockwell Collins has tested the TSS data load procedure using the ARINC
615-3 data loaders shown in Table 4-2. It is recommended that one of these data loaders, or an upgraded version of one of these data
loaders, is used to load the Traffic Surveillance System Application (TSSA) or the ECU.
4.4.2.1. The TSS may be data loaded using one of two input buses and one of three output buses. Loading must be done using the
default speed of the bus. Refer to Table 4-1 for bus names, pin numbers, and bus speeds. Refer to Table 4-2 for a list of the data
loaders that the TSS-4100 has been tested with. Most standard ARINC 615-3/4 compatible data loaders should be able t o interface to
the TSS-4100. No special adaptor is called out for the TSS-4100. See the specifications of the applicable data loader for information
on the mating connector to be used.
4.4.2.2. The TSS-4100 needs one of the following sets of requirements in order to enter data load mode:
