Monitor Port — USB or RS-232
Monitor Port — USB or RS-232
Every RMC CPU module has a Monitor port. This port is used primarily to communicate from RMCTools to the RMC. The monitor port type depends on the RMC type:

RS-232 |

Note:
The Monitor Port does not affect any LEDs on the RMC.
Connecting from RMCTools to the RMC
Use a procedure based on your RMC type and connection method:
RMC75E or RMC150E via Ethernet
USB Monitor Port (RMC75E and RMC150E)
The USB Monitor port is a Universal Serial Bus (USB) "B" port. RMCTools communicates with the RMC75E and RMC150E via the USB Monitor port. The USB Monitor port cannot be used for any other purpose.
Use a standard USB "A" to "B" cable to connect your PC to the USB Monitor port.
The USB port is intended for configuration, programming, and troubleshooting purposes only. Do not leave it connected during normal machine operation.
The USB port is sensitive to electrical noise. In some cases communication may be lost. If communication cannot be reestablished, you may need to unplug and reconnect the cable.
RS-232 Monitor Port (RMC75S and RMC75P)
The RS-232 Monitor port is a DTE DB9 RS-232 serial port. RMCTools communicates with the RMC75S or RMC75P via the Monitor port. The RS-232 Monitor port may also be used to communicate with other devices via the DF1 serial protocol.
Using the RS-232 Monitor Port for Communication with a Host Controller
The RS-232 Monitor Port is primarily intended for communication with RMCTools on a PC. However, the RS-232 Monitor port may be used to communicate with host devices, such HMIs, PLCs, etc. The RS-232 Monitor port can be used at the same time as the other communication port, whether it be Serial or PROFIBUS.
Since the RS-232 Monitor Port communication protocol is fixed at the settings listed below, it can only communicate with devices that support the DF1 protocol. For details on how to use the RS-232 Monitor port for communications, see the Using Serial Communications topic.
RS-232 Monitor Port Settings:
DF1 Full-Duplex
38400 Baud
8 Data Bits
No Parity
1 Stop Bit
CRC
