3.6.1.4 I/O and Gyro Strip Connector
The I/O and gyro strip connector can receive analog gyro output signals such as
Synchro and Step by Step.
Figure 3-17 Layout of the I/O & Gyro Strip Connector Pins
SW1 and SW2 of the I/O & gyro connector can control the TX mute function of the
modem by “contact closure” when the antenna is in the blockage or the preset block area
(refer to the operation section). Also, SW1 and SW2 supply the selection signal to coax the
switches in VSAT dual-antenna configurations.
The user can select ‘Contact Closure’ or ‘DC 5V Output’ by SW1 and SW3 of the ACU
board, as shown in Figure 3-20 below.
