The Serial Port Setup COMMREQ function can be used to activate a Modbus RTU
protocol over a serial port. To configure the Serial Port COMMREQ Data Block on
CPE115, refer to section 6.1.6 of the PACSystems RX3i and RSTi-EP CPU Reference
Manual, GFK-2222. The serial ports support Modbus RTU Slave and Serial I/O
protocols only.

Hardware Installation

Initial Checks

Upon receiving your equipment, carefully inspect all shipping containers for damage.
If any part of the system is damaged, notify the carrier immediately. The damaged
shipping container should be saved as evidence for inspection by carrier.
As the consignee, it is your responsibility to register a claim with the carrier for
damage incurred during shipment. Emerson will fully cooperate with you, however,
should such action be necessary.
After unpacking the equipment, record all serial numbers. Serial numbers are
required if you should need to contact Customer Care during the warranty period. All
shipping containers and all packing material should be saved should it be necessary
to transport or ship any part of the system.
Verify that all components of the system have been received and that they match
your order. If the system received does not agree with your order, contact Customer
Care.
