*1 The MES interface module distinguishes 10BASE-T from 100BASE-TX depending on the device
on other end.
For connection with a hub not having the auto-negotiation function, set the hub side to half-duplex
auto communication mode.
*2 This number applies when a repeater hub is used.
When using a switching hub, check the number of cascaded stages with the manufacturer of the
hub to be used.
*3 For the maximum segment length (a length between hubs), consult with the manufacturer of the
switching hub used.
