GPS
The EMMA (IC4200) performs serial communication with the GPS module (GP-1019 board) through the HN-415 and
CN-3723 boards. Furthermore, the EMMA (IC4200) acquires position information and time information to be used for
recording from the GPS module (GP-1019 board).
Real time clock (RTC)
The EMMA (IC4200) makes settings for the RTC (IC4600) connected through the serial bus and reads RTC data.
This RTC (IC4600) is backed up by the lithium button battery on the FP-208 board.
Temperature sensor
The EMMA (IC4200) reads temperature information from the temperature sensor (IC4601) connected through the serial
bus.
InfoLithium battery communication
The EMMA (IC4200) supports the InfoLithium battery of SMBus specifications.
The battery connector (serial connector) is connected to the EX VINE (IC404) on the FP-208 board through the RE-326
and MB-1210 boards. Battery authentication, type, remaining time, and other information are read and are sent to the
EMMA (IC4200) through serial bus communication.
Fan control
The EMMA (IC4200) monitors imager temperature (PA-422 board) and main board (DPR-362 board) temperature to
perform PWM control for the EX VINE (IC404) on the FP-208 board. The PWM signal is sent to the fan power supply
circuit on the RE-326 board through the MB-1210 board to control fan speed.
The EMMA (IC4200) also detects the fan rotation speed and sends the detection result to the EX VINE (IC404) on the
FP-208 board.
Two fans are installed and are connected through the connectors (CN8 and CN13) on the MB-1210 board.
TALLY control
The REAR TALLY (LED-529 board) is connected to the BOTTOM TALLY (AXM-52 board) in series through the
MB-1210 and DPR-362 boards.
These TALLY LEDs and the VF TALLY LED are controlled by one signal and can be lit from the EMMA (IC4200)
and the ROSETTA (IC0100).

AXM-52 Board
• The AXM-52 board mounts two input 2-channel analog/digital audio input connectors (3-pin XLR type) (CN101,
CN102). This board mounts [LINE, AES/EBU, MIC] selection switches (S101, S102) corresponding to each
connector channel.
• This board mounts an output 2-channel analog audio input connector (5-pin XLR type) (CN103).
• This board relays signals from the +48V setting switch (S101, S102) on the SW-1632 board.
• This board relays the input 2-channel XLR-type 3-pin connector detection board (DET-60 board).
RX-136 Board
The RX-136 board mounts an analog/digital wireless D-sub 15-pin connector (CN1), a circuit to support two
communication formats: WRR-855 communication and asynchronous communication, and an analog audio signal
amplifier. This board also controls digital audio signals. The FPGA (IC801) on the AU-360 board performs wireless
control.
