Overview
The RMA PLUS is a high-speed communication gateway used to access data from up to four busses via
Ethernet, USB or serial. One of the primary features is the ability to proxy (route) Watbus transactions
over Ethernet and USB to all devices connected to the high-speed Watbus network. This feature is
useful for system configuration and monitoring.
The other core feature is to allow field bus connections to custom data sets managed asynchronous to
field bus activity. This same model is used for data logging, system configuration and the HTTP server.

Connections and Wiring
Slot C Power Connection
Earth Ground
The USBH and USBD connector bodies are grounded to earth using the wire trap found on the bottom of
the case. To ground the connectors, insert a ground wire into the trap as viewed from the case bottom.
This earth ground is not connected to the power.

Figure 4 - Ground Wire Insertion
Use 18 –26 AWG Solid or Stranded, Trim Length 3.5 ± 0.5mm (0.138 ± .02”). Twist wire to remove.
RM System Connections
The RM system accessed by a RMA PLUS module can be installed as stand-alone modules or can be
interconnected on the DIN rail as shown below. When modules are connected together as shown,
power and communications are shared between modules over the modular backplane interconnection.
Therefore, bringing the necessary power and communications wiring to any one connector in slot C is
sufficient. The modular backplane interconnect comes standard with every module ordered and is
generic in nature, meaning any of the RM modules can use it.

Version 1.0 PN: 2042-8198
Page 13 of 75 DN: 10-32813
The modules can also be mounted in different locations and the backplane connected via wires in a Split
Rail configuration as shown in the figure. Notice in the split rail system diagram that a single power
supply is used across both DIN rails. One notable consideration when designing the hardware layout
would be the available power supplied and the loading effect of all of the modules used.
Watlow provides three options for power supplies listed below:
•90-264VAC to 24VDC @ 31 watts (Part #: 0847- 0299-0000)
•90-264VAC to 24VDC @ 60 watts (Part #: 0847- 0300-0000)
•90-264VAC to 24VDC @ 91 watts (Part #: 0847- 0301-0000)
With regards to the modular loading affect, maximum power for each is listed below:
•RMCxxxxxxxxxxxx @ 7 watts / 14VA
•RMEx-xxxx-xxxx @ 7 watts / 14VA
•RMHx-xxxx-xxxx @ 7 watts / 14VA
•RMLx-xxxx-xxxx @ 7 watts / 14VA
•RMSx-xxxx-xxxx @ 7 watts / 14VA

Theory of Operation
Configuration is accomplished by way of comma separated variable (.csv) files located on the native file
system. Based on the model number, configuration and feature availability, various configuration files
will be loaded into RAM. Configuration files are only read on initialization. Therefore, when changes are
made, the device must be reset for changes to take effect.
When the RMA PLUS comes out of reset, it reads the file “nor:\Setup.csv.” Depending on the model
number, the records in this file give the firmware more details about how to proceed with initialization.
Getting Started
Install USB Drivers (Windows® 7, 10)
See the file RMA PLUS USB Device Driver Installation for details.
Configure Ethernet
1. Connect a Mini-B USB cable to the RMA PLUS and launch Dashboard. The discovered RMA PLUS
should be under the “USB Devices”tree node.
Figure 10 - Dashboard: USB Devices subtree
2. Expand the RMA PLUS to see basic device information.
