SYSTEM (BAS)
CONFIGURATION
Connect the BAS Modbus wiring to COM2 of the S7999D and
ensure all S7999D devices have unique Modbus addresses
as defined in Fig. 6.
BAS Modbus message timeout should be set to 1.0 seconds
or higher. This means it could take up to 1.0 seconds (max) for
the System Display to reply to a BAS message.
Retries: BAS must setup retries upon timeout to ensure the
Modbus request is accepted.
BAS Modbus poll rate should be set to 100 ms (milliseconds)
or slower. This means that the BAS should wait for a minimum
of 100 ms (milliseconds) after receiving a Modbus message
from Sola before sending a new Modbus message.

QUICK SETUP

1. Make sure the S7999D 8-pin connector is properly
aligned and pressed firmly in place.
2. Make sure the wires between the 8-pin connector and

3. Make sure the power supply is connected securely to
the power source.
