Comparison with products in the same series

Compared to ELPRO’s existing 240U-E, 905U-E, and 805U-E, the 245U-E series has core advantages in terms of speed and encryption level. The key parameter comparisons are as follows:

Product Model Frequency Band Protocol Standard Maximum Rate Transmission Power WDS Supports Highest Encryption Level

245U-E-G 2.412-2.462GHz 802.11b/g 54Mbps 15-400mW is WPA2/802.11i

245U-E-A 5.20-5.825GHz 802.11a 54Mbps 15-400mW is WPA2/802.11i

240U-E 2.462-2.62GHz 802.11b 11Mbps 100/300mW is WPA-PSK (AES128)

905U-E 902-928MHz 802.11-FHSS 200Kbps 100mW-1W No AES128

805U-E 869MHz 802.11- Fixed frequency 72Kbps 10/100-500mW No AES128

Note: The maximum transmission power limit for modules shipped in Europe/South Africa is 100mW, and each product frequency band is configured according to national regulations.

Compliance and Certification

The product meets multiple industrial compliance standards:

EMC：EN 301 489-17、FCC Part 15、EN 300 328、FCC Part 15.247、RSS 210；

Safety regulations: EN 60950, CSA Class I, Division 2 (to be determined);

Quality: ISO 9001:2000, registration number 282.

System design advantages

Support WDS+spanning tree self-healing mesh network. In case of on-site single point failure (such as AP power outage), network traffic will be automatically forwarded through redundant APs to ensure uninterrupted communication between LANs;

Seamless conversion between serial port and Ethernet enables bidirectional data transmission between on-site devices and remote LAN. Modbus master AP can actively poll slave I/O data;

The online diagnosis and configuration function runs through the entire network, assisting system design and fault analysis. Module expansion does not require complex configuration, and DHCP automatically assigns IP addresses.
