1.
Make sure that the user memory default switch is turned OFF (set to the
left). If the default switch is turned ON (set to the right) and power is turned
ON, the memory will return to the default settings (be formatted). This
switch should always be turned OFF, except when processing errors.
2.
Mount the ASCII Unit to the Backplane.
3.
Turn OFF the power to the CPU Unit, and connect the RS-232C port (COM
1 in this example) to communications port #1 for the C200H-ASC11/
ASC21 or the terminal port for the C200H-ASC31 using an RS-232C ca-
ble.
4.
Set the switches on the front panel of the ASCII Unit as follows:
• Unit No. switch.
• Set the START/STOP switch to START.
• Terminating resistor switch, 2-wire/4-wire switch. (Only set when using
communications port #2 of the C200H-ASC21.)
5.
Turn ON the power to the CPU Unit.
6.
Using a PC peripheral device (such as a Programming Console), perform
the following operations.
a)
Create an I/O table
b)
Set the DM Area of the CPU Unit (DM m to m + 7). (See
3-2 DM Area

for details.)
