Coated modules are X20 modules with a protective coating for the electronics component. This coating protects
X20c modules from condensation and corrosive gases.
The modules' electronics are fully compatible with the corresponding X20 modules.
For simplification purposes, only images and module IDs of uncoated modules are used in this data
sheet.
The coating has been certified according to the following standards:
• Condensation: BMW GS 95011-4, 2x 1 cycle
• Corrosive gas: EN 60068-2-60, method 4, exposure 21 days
Description:
According to Ethernet specification IEEE 802.3, the transmission duration of a frame of minimum length must
always be greater than the round-trip delay time (RTD). RTD is the time needed by a data packet to travel from
one end of the network to the other.
If this is not observed, collision detection can no longer be guaranteed.
Illustration of RTD
When using copper cables, the maximum distance is generally 100 m. Since there are often many different devices
with different PHYs in a network, the propagation delay of the frames changes due to the different latency of each
PHY. This also affects the network size, and collision detection can no longer be guaranteed at 100 m.
The following parameters are specified for a network:
– Transfer rate: 100 Mbit/s
– Cable length: 100 m
– Number of hubs: 2
– Hub propagation delay of a frame: 1 µs
– Minimum frame size in the Ethernet network: 72 bytes
Corresponding to the previous example, the following situation occurs in a network with 3 hubs and 100 m cables:
• The transmission duration of a frame of minimum length is 5.76 µs.
