8. Network Protocols
Network protocols are formatting rules that specify how data is sent and received between devices.
Protocols are necessary for devices to interact with each other
Protocols MCS controllers support:
Bacnet
Modbus
LonTalk
Johnson N2
MCS

9. Network Protocols
The MCS Controllers support the following network protocols:
Over Ethernet
Over
RS485
Over LonWorks

10. MCS Network Adaptors
MCS uses five different optional network adapters:
Hardware Adapters
MCS-485-Gateway (RS232 - RS485)
MCS-Ethernet (Ethernet - RS232)
MCS-USB-RS232 (USB - RS232)
Hardware & Protocol Adapters
MCS-BMS-Gateway (Bacnet MSTP, LonTalk, Johnson N2)
MCS-Bacnet-Router2 (Bacnet IP)

11. MCS-485-Gateway Converts between
RS485 and RS232
Used with the MicroMag for a connection to:
PC (MCS-Connect)
MCS-Touch (MCS-Connect)
MCS-Ethernet
Can be powered from MCS Controller
Only hardware conversion, does not change protocol

12. MCS-Ethernet Converts between
Ethernet and RS232
Used with the MicroMag for Ethernet connection to:
Internet
Comes with 120V wall outlet power adapter
Only hardware conversion, does not change protocol

13. MCS-USB-RS232 Converts between Used for PC (MCS-Connect) communication
USB and RS232
Used for PC (MCS-Connect) communication
Powered through USB port
Only hardware conversion, does not change protocol

14. MCS-BMS-Gateway Converts Bacnet MSTP (RS485) to:
LonTalk (LonWorks)
Johnson N2 (RS485)
Converts Bacnet IP (Ethernet) to:
Bacnet MSTP (RS485)
Only supports one MCS-Magnum or MicroMag

16. MCS-Magnum Communication
The MCS-Magnum comes with two hardware communication ports:
RS485 Port
Ethernet Port

17. MCS-Magnum Communication
The MCS Keypad has a built in MCS-485-Gateway and is connected to the RS485 port on the MCS-Magnum
These two ports cannot be in use at the same time with different protocols:
RS485 port on the MCS-Magnum
RS232 port on the MCS-Magnum Keypad
RS232 Port
RS485 Bus

18. MCS-Magnum RS232
The MCS-Magnum can be connected to a PC via MCS-Connect using RS232 located on the MCS-Magnum Keypad
The PC may require usb to RS232 adapter, MCS Part # (MCS-USB-RS232)
MCS-USB-RS232
MCS-PC9-MM cable PC
(MCS-Connect)
The RS485 cannot be used with different protocols when the RS232 is used

19. Building Management System
MCS-Magnum RS485
Using the RS485, the MCS-Magnum can be connected to the BMS (Modbus RTU or MCS 485)
Building Management System .
RS485
The RS232 cannot be used with different protocols when the RS485 is used

20. Wiring Multiple MCS Controllers
Using the RS485, the network must be wired controller to controller
Star configurations not allowed
Up to 30 controllers can be wired together
Correct
Incorrect .

21. MCS-Magnum Ethernet
Using the Ethernet, the MCS-Magnum can be connected to
BMS (Bacnet IP or Modbus IP)
