Chapter 5 Internal Control
The operation of the transmission wave module model GX changes as follows.
"Start-up"
After the power is turned on and the hardware is reset, the module initializes the internal circuits,
outputs the module ID as a startup message to the UART interface, and then transitions to the
idle state.
"Idle"
When the module is idle, it waits for a command from the UART interface, and if no command
(or trigger signal) is received, there is no RF action.
"Trigger action"
The module can identify that the trigger signal (SYNC-IN) is low in all states. But it should following a
Prepare main flash Usart command, then the SYNC-IN signal comes.
After identifying the trigger signal, the trigger transmission operation is performed. (Minimum time of
trigger signal is 100uS or more) To implement one-shot trigger operation, do not set the trigger
signal to the Low state for 50mS or more.
"Command operation"
The module can receive UART commands in any state, When the command received from the UART
interface is valid, the processing specified by the command is executed. Command processing is a send
operation or a message response to the UART interface. After the command execution is completed, this
product transits to the idle state.
"Transmission operation"
As a transmission operation, the module controls the wireless circuit and transmits the wireless
message specified by the trigger signal or transmission request command in the preset wireless mode.
After execution of the transmission operation is completed, this product transits to the idle state.

Chapter 6 Embedded Specifications
The transmission radio wave module model GX is designed to be used by incorporating it into the Seconic
L-858-D exposure meter. It can be incorporated into other equipment, but it must meet the following
conditions.
6.1 Mechanical conditions
As shown in the figure below, the mechanical conditions for installing the module are as follows:
(CON) must be mechanically adapted. In addition, the space in which the board is installed does not allow
the wireless performance of the antenna installed in the module to be demonstrated simply by providing the
minimum board space.
Concept of required space (clearance)
Do not use metal or resin with an electrostatic shielding property for the casing (casing) of the
parent device to be incorporated. If the module part is covered with metal parts, radio waves
cannot be emitted to the outside.
In order to maximize the wireless performance (communication distance performance) of the
antenna, make sure that there is no object around the antenna part of the module.
Furthermore, even if a resin housing is used, the characteristics will deteriorate if the antenna
part of the module and the case are close to each other. To avoid this, make sure there is a gap of at least
3 mm between the back side of the module (the side without the component/shield case) and the resin
case of the embedded parent device.
