Introduction
The Niobrara MUCM is a TSX Momentum® compatible module that is capable of
running multiple applications for performing communication translations between se-
rial protocols. This document covers an application that allows masters of various
protocols to communicate with DF1 devices. This setup allows the master to be
placed onto an existing Data Highway network via a DF1 to Data Highway bridge.
One application is required to be loaded into the MUCM: app1.qcm contains the DF1
and other serial drivers, and the configuration software. This application must be run-
ning for the system to properly perform.
Port 1 of the MUCM is to be connected to the master to provide the interface to the
DF1 device. Port 2 is the DF1 port, and can be connected point to point with the DF1
device or, optionally, could be connected to a daisy chain of DF1 half duplex devices
using RS-232 to RS-485 convertors. The MUCM supports many DF1 devices includ-
ing Helm Instrument Company’s Loadgard Serial Interface. These devices are ac-
cessed via the master protocol by selecting the node ID assigned to each slave (0-254).
Port 1 is also the configuration port. When Application 2’s RUN/HALT switch is
switched to the memory protect mode, it interfaces to an ASCII terminal to provide
the user with a simple way to reconfigure the two serial ports.
The MUCM may be mounted on a DIN rail, or directly to a wall via mounting holes.

Installation
Module Installation
1 Mount the MUCM in an appropriate location on a DIN rail or in a cabinet.
Software Installation
The application files for the MUCM are included in the DF1.ZIP file. This file must
be unzipped using an application like PKUNZIP.EXE. A copy of PKUNZIP is in-
cluded on the standard NR&D software disk and is also available at
www.niobrara.com. The latest version of the DF1.ZIP file is located at
ftp.niobrara.com/mucm/DF1/DF1.zip
The latest version of this document in pdf format is located at:
ftp.niobrara.com/mucm/DF1/DF1.pdf
The DF1 communications protocol is available from Allen-Bradley at:
www.ab.com/manuals/cn/17706516.pdf
Serial Connections to the MUCM
Port 1 to Master
If connecting to a Modicon PLC, the Niobrara cable MU2 is ideal for this connection
since it includes a screw terminal RS-232 connection for the MUCM and a 9-pin male
RS-232 Modicon-style pinout for the PLC. This cable pinout is described in Figure
2-1.

Figure 2-1 MUCM to RS-232 DTE Port (9-pin) (MU2 Cable)
For an RS-485 connection to SY/MAX devices, Port 1 of the MUCM will be set to be
RS-485. The Niobrara cable MU7 is ideal for this connection since it includes an
RJ45 RS-485 connection for the MUCM and a 9-pin male RS-485 SY/MAX-style
pinout at the other end. This cable pinout is described in Figure 2-2.
Figure 2-2 RS-485 SY/MAX Port (9-pin) (MU7 Cable)
The master must be configured to match the serial settings of the MUCM Port 1. The
supported baud rates by both units are 1200, 2400, 9600, and 19200. 19200 baud is
the default.

Port 2 to the Personal Computer
A physical connection must be made from the personal computer to the MUCM in or-
der to download the applications. This link may be a serial connection from a COM
port on the personal computer to the RS-232 port on the MUCM. The Niobrara MU1
cable may be used for this connection. This cable is shown in Figure 2-4.

Loading the Applications into the MUCM
The MUCM is rapidly evolving so be sure to upgrade the firmware in the module be-
fore loading the latest version of APP1.QCC. Most likely the QCOMPILE.EXE has
been updated so be sure to use the newest version. Firmware upload is as follows:
1 Move the RUN/LOAD switch on the module to LOAD.
2 Only the Pwr light should be on.
3 Connect the PC to MUCM Port 1 with an MU1 cable.
4 From the command line enter

Be sure to have the colon after the PC’s com port name. The download will only
take a few minutes and will inform when finished.
5 Change the switch back to RUN.
6 It is a good idea to press the RESET button after a firmware change.
Next, load APP1.QCC into the MUCM by the following method:
1 Move Switch 1 to Halt.
2 Connect the PC to MUCM Port 1 with an MU1 cable.
3 Load the QRPC file with qload.
> qload 1 app1 com1:9600,e,8,1 -a
Will load the file into application 1’s flash and set the program to automatically
start on power-up.
4 Place Switch 1 in RUN. The RN1 light should come on.
5 Place Switch 2 in the HALT position until ready to configure the MUCM.
DF1 to MUCM Port 2
After the software has been installed into the MUCM, Port 2 becomes the DF1 port.
The connection for the MUCM to the Allen-Bradley DF1 to Data Highway convertor
should be accomplished with the Niobrara SC902-ST if the convertor’s port is set to
RS-232(Refer to Figure 2-3). If the convertor’s port is set to RS-422, the diagram for
that cable is located in figure 2-5.
