Notes: some module modem will not show the IMEI info with such operation.

11.8 Pin Code

Some sim has pin code. If there is, please input the pin code when you config the parameters of the router.

If there is none, please just keep blank. Please click "Save" button and reboot the router after the

configuration.

If sim card has pin code, and pincode is activated, the router will dialup and there is no indication in the sys log.

If pin code is wrong set, the router will not dialup and get error while it send APN parameter to Base Station.

Here we just test the router's DTU feature is working or not. We make H685m as DTU client, and get a PC to

run a server tool software.

Step 1) check if your device is RS232 or RS485 port, should be same with the H685m series router.

Step 2) get the H685m's DTU feature right setted as follows,
