This manual introduces upgrading firmware methods of Serial to Ethernet Converter(Include USR K2/K3/USR N510/USR N520/USR N540, USR-TCP232-ED2/E2/T2/S2/USR-TCP232-410S/USR-TCP232-302/USR-TCP232-304/USR-TCP232-306)
And manual introduces two methods: One is normal upgrading method and another is special method to upgrade Serial to Ethernet Converter when user upgrades Serial to Ethernet Converter by normal method unsuccessfully and can’t search module in LAN any more.
1. Normal upgrading method
Note: Please be cautious to upgrade firmware. If upgrading firmware by normal upgrading method and special upgrading method both unsuccessfully, user has to return module to repair and pay the freight by self.
Before upgrading, user should note the following several points: close the windows firewall, close antivirus program, disable wireless network card, disable other wired network cards except the wired network card which is connecting to Serial to Ethernet Converter or same router as Serial to Ethernet Converter.
1.1. Hardware connection
Plug in DC power adaptor to power the module. Then connect module to PC by Ethernet cable or connect module to router/switcher which in same network as PC by Ethernet cable.(If user connects module to router/switcher which in same network as PC by Ethernet cable, user must configure module’s static IP address in same network segment as router)
1.2. Upgrade firmware
User needs setup software for Serial to Ethernet Converter to upgrade firmware and can download setup software from:
https://www.usriot.com/usr-tcp232-m4k3-setup-software/ (For USR-TCP232-ED2/E2/410S/, USR-K3/N510/N520/N540)
https://www.usriot.com/usr-m0-setup-software/ (For USR-TCP232-T2/S2/302/304/306, USR-K2)
Take USR-N510 as example and connect N510 to router by Ethernet cable.
Step 1: After running the setup software USR-TCP232-M4K3 Setup Software V126.96.36.199, search the N510 in LAN. Then configure N510 static IP address in same network segment as router.
Figure 1 Search module and configure static IP
Step 2: After saving above configuration and restarting the module, user can upgrade firmware as follow:
Figure 2 Upgrade firmware
Write correct module IP address and MAC address, then choose firmware file and click ‘Program’ to upgrade firmware.
Displaying ‘Upgrade successfully.please restore factory’ as follow figure means upgrading successfully. Then user should reset module to default settings.
Figure 3 Upgrade successfully
2. Special upgrading method
Note: When user meets the situation that upgrading Serial to Ethernet Converter by normal method unsuccessfully and can’t search module in LAN, and tries to upgrade firmware by this special method, please confirm that upgrading unsuccessfully doesn’t caused by upgrading environment(such as firewall, antivirus program) firstly.
2.1. Hardware connection
Plug in DC power adaptor to power the module and connect module to PC by Ethernet cable directly.
2.2. Upgrade firmware
Take USR-N510 as example.
Step 1: Run the setup software USR-TCP232-M4K3 Setup Software V188.8.131.52 and open ‘Firmware Upgrade’ interface as 1.2.Upgrade firmware Step 2.
Figure 4 Upgrade firmware
On ‘Firmware Upgrade’ interface, configure parameters as follows:
Then select firmware file and click ‘Program’ to upgrade firmware.
Note: Please keep powering the module and keep connection between PC and module by Ethernet cable during upgrading process.
