Using RMCWin 3-7
current communication path and the state of that communication path (for example, "COM1:
Offline"). A path can be in any of the following states:
State Description
Closed RMCWin is not connected to an RMC, and it is not using the
communication path at all.
Offline RMCWin is not connected to an RMC, but it is polling the
communication path for an RMC to become available.
Connecting RMCWin detected an RMC, but is in the process of connecting and
validating the RMC configuration.
Online RMCWin is currently connected to an RMC.
Loader RMCWin is currently connected to an RMC, but the RMC is running
its loader firmware. The only operation allowed in the loader is
downloading new firmware. See Downloading New RMC100
Firmware for details on updating the firmware.
Picking the Right Communication Driver
RMCWin offers numerous ways to connect to an RMC. All of these ways use one of three drivers,
each of which is listed below. Click the link following each for a detailed description and wiring
diagrams:
• Serial: This is the easiest method to use, but—unless an RS422/485 segment is inserted into the
cable—the maximum cable length is typically limited to 50 feet and there is no isolation. In either
case, only a single RMC can be accessed per serial port.
See Communication Drivers: Serial Overview.
• TCP/IP Direct to RMC-ENET: This method requires an RMC ENET module, but otherwise gives
the best performance, allows routing and addressing multiple modules, and provides isolation.
See Communication Driver: TCP/IP Direct to RMC-ENET Overview.
Note: If your computer has a firewall, it may prevent RMCWin from finding RMC100s on your
Ethernet network from the Communications tab in the Options dialog. See the Setting the
Firewall to Allow RMC100 Ethernet Browsing topic for details.
• TCP/IP-to-RS232 Bridge: This method adds many of the benefits of Ethernet—it allows routing
and addressing multiple modules and provides isolation—but at the expense of performance, it
can work with all RMCs, not just those with the RMC ENET module. This is done by using a
TCP/IP-to-RS232 Bridge device.
See Communication Driver: TCP/IP-to-RS232 Bridge Overview.
Selecting and Configuring a Communication Driver
The first way to select or configure a communication driver is to use the Communication tab of
the Options dialog box.
