7.1 Communication specifications
The following table shows the communication specifications for built-in Ethernet ports of
the CPU module.
* 1 : Straight cables can be used.
Crossing cables can also be used for connecting the Built-in Ethernet port QCPU with GOT
directly using an Ethernet cable.
* 2 : STP cables are recommended for the use under noisy environment.
Hubs with 10BASE-T or 100BASE-TX ports
*3
can be used.
The maximum number of devices that can access to one CPU module simultaneously is
16.
* 3 : The ports must comply with the IEEE802.3 10BASE-T or IEEE802.3 100BASE-TX standards.
POINT
1. When connecting with a hub, the Built-in Ethernet port QCPU determines the
cable used (10BASE-T or 100BASE-TX) and the communication mode (full-
duplex or half-duplex). Set the communication mode to the half-duplex mode
on the hub side when the hub that does not have the auto-negotiation function
is used.
2. The module operation is not guaranteed if any of the following connection is
used. Check the module operation on the user side.
• Connections using the Internet (general public line) (Connections using
Internet connection service provided by Internet service providers and
telecommunications carriers)
• Connections using devices in which a firewall is installed
• Connections using broadband routers
• Connections using wireless LAN
