Note: You must use battery back-up.
The ASCII module draws 1.3A from the backplane. Be sure that the total
current drain of all modules in the chassis does not exceed the maximum
for the backplane and power supply.
If you use an existing system, consider disconnecting all other chassis
except the one containing your ASCII module. Disconnect field wiring
arms from output modules for safety purposes.
How to Connect Your Equipment
Connect your equipment with the appropriate cables (Figure 1.1 for
Mini-PLC-2/15 controllers, Figure 1.2 for PLC-2/20 or-2/30 controllers).
Be sure that the end of your IT/DH adapter cable labeled CHANNEL B is
connected to channel B on the industrial terminal.
