4.1.2.
Operation Procedures of Using TE-B Alone
1.
Install USB-to-UART driver which can be downloaded from the following link:
https://www.wch.cn/downloads/USBMSER_exe.html
2.
Insert a Micro-SIM card into J0604, and please note that a NB-IoT or Cat M USIM card should be
selected according to actual needs.
3.
Connect the rod antenna with SMA connector on J0501 (Main antenna connector).
4.
Switch S0403 (PON_TRIG Switch) to “HIGH” state.
5.
BG95xA-GL:
Connect the J0301 (USB-to-UART interface) with PC via a Micro-USB cable. After turning on TE-B,
serial port information will be shown on “
Device Manager
” of PC.
1)
Among them, "
WCH USB-SERIAL Ch A (COM23)
" is connected to the main UART of
BG95xA-GL, which can be used for data transmission and AT command communication.
2)
Among them, "
WCH USB-SERIAL Ch B (COM21)
" is connected to the debug UART of
BG95xA-GL, which can be used for RF calibration and SFP log output.
3)
Among them, "
WCH USB-SERIAL Ch C (COM22)
" is connected to DM UART of BG95xA-GL,
which can be used for firmware upgrade, software debugging, DM log output, GNSS data and
NMEA sentences output.
4)
Among them, "
WCH USB-SERIAL Ch D (COM20)
" is connected to the GNSS UART of
BG951A-GL, which can be used for GNSS data and GNSS NMEA sentence output, and GNSS
firmware upgrade.
6.
BG950S-GL:
Connect the J0301 (USB-to-UART interface) with PC via a Micro-USB cable. After turning on TE-B,
serial port information will be shown on “
Device Manager
” of PC.
1)
Among them, "
WCH USB-SERIAL Ch A (COM23)
" is connected to the main UART of BG950S-
GL, which can be used for data transmission and AT command communication.
2)
Among them, "
WCH USB-SERIAL Ch C (COM22)
" is connected to DM UARTs of BG950S-GL,
which can be used for firmware upgrade, software debugging, RF calibration, log output, GNSS
data and NMEA sentence output.
