| Key Features | |
|
Baud rate The maximum theoretical speed at which a serial communication interface can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across different serial devices and adapters.
|
1000 Kbit/s |
| Cabling technology | 10/100Base-T(X) |
|
Ethernet LAN ports Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.
|
1 |
|
Flow control support Indicates whether a device includes hardware or firmware that can manage the flow of data on its interfaces, such as enabling or disabling automatic pause frames, handling congestion, or providing other traffic‑control mechanisms. A value of "Yes" means the feature is present and can be configured; "No" indicates it is not available.
|
Yes |
| Networking standards | IEEE 802.3,IEEE 802.3u |
|
Operating relative humidity The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.
|
5 - 95% |
|
Operating temperature The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.
|
0 - 55 °C |
|
Safety A list of safety and regulatory certifications that a product complies with, such as CE, UL, FCC, or other regional standards.
|
IP-30 |
|
Serial interface type The type of serial communication interface supported by the product, such as RS‑232, RS‑485, RJ‑45, or SATA. It indicates which physical connectors and protocols are available for data exchange with other devices.
|
RS-422/485 |
|
Serial ports Represents how many serial communication connectors (e.g., RS‑232, RS‑485) are physically present on the product. The value is a simple integer indicating the total count of serial ports, regardless of specific model or configuration.
|
8 |
|
Server operating systems supported A list of operating systems that the server product can run or support, including specific versions and architectures when relevant. Each value represents a distinct OS compatible with the hardware.
|
Windows Server 2008,Windows Server 2008 x64 |
|
Storage temperature The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.
|
-20 - 85 °C |
|
Supported network protocols A list of network communication protocols that a device can use or support, such as TCP/IP, HTTP, HTTPS, FTP, DHCP, DNS, and various wireless standards. Each protocol is represented by its standard name and may be separated by commas or slashes in the source data.
|
ICMP, IP, TCP, UDP, DHCP, BOOTP, Telnet, HTTP, RFC2217 |
|
Wi-Fi Indicates whether the product has built‑in Wi‑Fi capability, allowing it to connect to wireless networks without requiring external adapters or dongles.
|
No |
