9. Scroll and select 485(Modbus over RS-485); press SET.
10. Use the ▲ button and scroll to  (building
automation time-out); press SET.
11. Use the ▲▼ buttons to scroll to the desired time-
out (in minutes); press SET. Note: this is the
amount of time the S3C Control waits before a
communication alarm is generated after loss of
communication.
12. Use the ▼ button and scroll to N (network parity);
press SET.
13. Use the ▲▼ buttons to scroll to the desired parity
setting (oe, e or dd); press SET. Note: The
parity selection must match the BAS controller.
14. Use the ▼ button and scroll to ud (baud rate); press
SET.
15. Use the ▲▼ buttons to scroll to the desired baud rate
(115 = 115000, 768 = 76800, 576 = 57600, 384 =
38400, 192 = 19200, 96 = 9600); press SET. Note:
The baud rate selection must match the BAS
controller.
16. Use the ▼ button and scroll to dd(address); press
SET.
17. Use the ▲▼ buttons to scroll to the desired address
setting; press SET. Note: Each S3C Case Control
on the network must have its own unique
address.
18. Press the ESC button three times to exit the menu and
return to the default display.

SUPPORT BACNET OVER RS485 TO
THE BAS
1. From the default display, press the  button. The
display will show   .
2. Use the ▲▼ buttons to enter the administrator
password and press SET.
3. The display will show (will skip to Process Values if
system is self-contained).
4. Press the SET button and  (Process Values) will be
displayed.
5. Use the ▼ button and scroll to Ne (network
configuration); press SET.
6. Use the ▲ button and scroll to  (building
automation); press SET.
7. Scroll to e; press SET.
8. Use the ▲ button and scroll to  (building
automation protocol); press SET.
9. Scroll and select 485 (BACnet over RS-485); press SET.
10. Use the ▲ button and scroll to  (building
automation time-out); press SET.
11. Use the ▲▼ buttons to scroll to the desired time-
out (in minutes); press SET. Note: This is the
amount of time the S3C Control waits before a
communication alarm is generated after loss of
communication.
12. Use the ▼ button and scroll to N (network parity);
press SET.
13. Use the ▲▼ buttons to scroll to the desired parity
setting (oe, e or dd); press SET. Note: BACnet
standard specifies that the parity be set to oe.
14. Use the ▼ button and scroll to ud (baud rate); press
SET.
15. Use the ▲▼ buttons to scroll to the desired baud rate
(115 = 115000, 768 = 76800, 576 = 57600, 384 =
38400, 192 = 19200, 96 = 9600); press SET.
16. Use the ▼ button and scroll to 485 (BACnet subnet
number); press SET. Note: The subnet number is
important when the S3C Control is used as a
router or the subnets are connected together. If
all system components on the networks have unique
addresses, then the BACnet subnet number is not
required.
17. Use the ▼ button and scroll to  (maximum
master); press SET.
18. Use the ▲▼ buttons to scroll to the desired maximum
master); press SET. Note: The maximum master
should be set to the maximum address of any
controller attached to the BAS controller via
RS-485 (per BAS communication port). This will
reduce communication loading on the network. For
example, if there are two case controllers with addresses
0 and 1 and two rack controllers with addresses 4 and
5 connected to the BAS controller with address 3 via
RS-485 on the same BAS communication port, then the
maximum master should be set to 5 (maximum of all
addresses).
19. Use the ▼ button and scroll to dd (address); press
SET.
20. Use the ▲▼ buttons to scroll to the desired address
setting; press SET. Note: Each S3C Case Control
on the network must have its own unique
address.
21. Press the ESC button three times to exit the menu and
return to the default display.
See the following figure for example BACnet network
configuration using RS-485 to the BAS.
