4.2.2 Expansion TSAM Addressing & Jumpers
Address switch SW102 on the front of the TSAM is used to set TSAM SPI bus addresses.
A Master TSAM always has address 0. Additionally, the Master TSAM drives the Main and Secondary
channel expansion transmit audio busses and receives audio on the Main and Secondary channel receive
audio expansion busses.
Slave TSAM units have addresses 1-7. The addresses must be sequential and no addresses may be
skipped.
The SW102 master/slave switch must be in the S position on all Slave TSAMs.
The Master TSAM controls the transmitter steering system. The MCU and control logic on the slave
TSAM operates only in a standby diagnostic mode. All of the Slaves I/O logic and audio switching are
controlled by the master TSAM MCU.

Table 2 Expansion TSAM Switch and Jumper Settings
0 = down, 1= up
Note: RS-485 Terminators
Jumpers E109-E112, and E125 install RS-485 terminator resistors on the expansion bus. The terminators
are always required on the first and last TSAMs in a system. This means the Master TSAM and the last
Slave TSAM always have these jumpers installed. All other Slave TSAMs have these jumpers removed.
