SYSTEM CONFIGURATION
(12)Connection to external devices
(a) RS-232 device
The following are precautions for connecting an RS-232 device to the RS-232
interface of the C Controller module.
• A receive error may occur on the target device when the C Controller module
or the target device connected to the C Controller module is powered on or
off, or reset.
• A receive error occurs on the target device if the target device side system is
started during data transmission from the C Controller module to the target
device.
• If an error occurred on the target device, take corrective actions according to
the instruction manual for the target device.
(b) Ethernet device
The following are precautions for connecting an Ethernet device to the 10BASE-T/
100BASE-TX interface of the C Controller module.
1) When the C Controller module was replaced and the IP address was changed
Reset the Ethernet device as well.
(If the Ethernet device retains the Ethernet address (MAC address) of the
communication target, ongoing communication may be disabled because the
C Controller module replacement and IP address change also changes the
Ethernet address (MAC address).)
Likewise, restart the C Controller module if the Ethernet device was replaced.
2) When an error occurred on the Ethernet device side
Take corrective actions according to the instruction manual for the Ethernet
device.
3) When VxWorks output an event or a message
VxWorks may output an event or an error message upon detection of a
network error when any of the following tools is connected to the C Controller
module.
• Workbench Shell or Tornado Shell
• Telnet
For events and messages, take corrective actions according to the following.
• Manual for VxWorks
• Help of Workbench or Tornado
For events and messages that cannot be handled, consult Wind River
Systems, Inc.
