C200HX/HG/HE Controller Link Units Section 4-3
4-3-2 Node Addresses
Set the node addresses of each Unit on the Network using the rotary switches
on the front of the Unit. The node address is used to identify each node in the
Network can be set to any number between 01 and 32.
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
Note 1. Always turn OFF the PC’s power before setting the node address.
2. Do not set the same node address twice within the same Network. An error
will occur if the same address is set for two different nodes. The ERC indi-
cator on the front of the Unit will light and either communications will stop,
or the INS indicator will not light and you will be unable to participate in the
Network.
3. The send sequence for the data link areas is determined according to the
sequence of node addresses for automatically set data links.
4. Assign node addresses consecutively beginning from 01 whenever possi-
ble to minimize Network construction time.
4-3-3 Baud Rates and Operating Levels
Set the following pins for the baud rate and operating level settings (DIP
switch).
Note 1. Always turn OFF the PC’s power before setting the baud rate or operating
level.
2. Keep pin 3 set to OFF. If it is turned ON, internal data may be erased.
Baud Rate (Pins 1 and 2) Set the same baud rate for all the nodes on the Network using DIP switch pins
1 and 2 on the front of the Unit. The baud rate is set as shown below.
The maximum transmission distance will also change according to the setting.
