Kramer Electronics FC-24ETH - Manual (Page 40)

36 Technical Specifications
In extremely demanding cases, we recommend that you take into account the
bandwidth limitations.
The total sustained data bandwidth that each device can handle for all ports
simultaneously is as follows:

FC-21ETH —150kbps

FC-22ETH —140kbps

FC-24ETH
—180kbps
9.2 Example Bandwidth Calculation
The FC-22ETH has two serial ports. Each serial port can support up to:

140kbps / 2 = 70kbps
If each of your protocol commands is 100 bytes, (that is, 800bits), you can safely
send and/or receive a minimum of 85 of these commands per second on each
serial port ((140kbps * 1024) / 800bits / 2 = 89.2). The same calculation applies to
all devices. A similar calculation applies when fewer ports are used at the same
time; in this case higher bandwidth per port can be achieved.
In critical applications requiring a lossless data transfer, we recommend that
communication on all the other ports is stopped when making a long file transfer
(for example, when performing a firmware upgrade via one of the serial ports).
