Operation Procedures

This chapter introduces how to use the 5G-REDCAP EVB for testing and evaluation of applicable
modules. Before the procedures below, ensure modules and the EVB are correctly assembled.

4.1. Turn On the Module

1. Connect the module TE-A to the EVB via connectors J0101 and J0103.
2. Insert a (U)SIM card into the (U)SIM card connectors (J0801/J0804) on the EVB.
3. Use cellular cables to connect the module TE-A to the EVB, and connect antennas to the EVB.
4. Connect the EVB to a 5 V/ 3 A power, then switch S1301 to ON, the module and the EVB will be
turned on. Then D1402 (Power supply ON/OFF indicator) will light up, which indicates that the power
supply for the whole EVB is ready.
5. Press the S1201 (PWRKEY) for at least 500 ms, then the module will be turned on and D1203
(module operation status indicator) will light up.
NOTE
1. If the PWRKEY has been switched to "TURN ON" side before the power supply is connected, the
module and the EVB will turn on automatically when the power adapter is connected.
2. The turn-on should be performed only after the EVB assembling is completed to avoid any possible
damage.

4.2. Turn Off the Module

There are two methods to turn off the module.
1. Turn off the module with AT+QPOWD. This is the best and the safest method. The module will log off
from the network and save data before turn-off. When turning off the module with AT command,
please keep PWRKEY at a high level after the execution of the turn-off command, otherwise, the
module will be turned on again after successful turn-off.
2. Turn off the module with PWRKEY button (S1201). Long press PWRKEY for at least 650 ms, then
the module will be turned off.
