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
RS-232 Monitor Port Wiring
Cable
The following options are available for the cable between the PC and the RMC70
serial Monitor port:
• Generic null-modem (female on both ends) serial cable
• Allen-Bradley PLC serial cable
• Modicon Modbus cable with a 9-pin male-to-female gender changer
• Siemens SIMATIC 505 Programmable Controller serial cable
• Any cable will work if pins 2, 3, and 5 on the RMC70-end of the cable are
connected as shown below.
