CHAPTER 3 SPECIFICATIONS
This chapter explains the performance specifications, functions, buffer memory, etc. of the
MES interface module and the MX MESInterface.
For general specifications of the MES interface module, refer to the following manual.
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
3.1 Performance Specifications
This section explains the MES interface module and the MX MESInterface performance
specifications.
(1) Transmission and interface specifications
*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.
