Page 9: Organization Of This Manual
Unpacking and Post Delivery Inspection identifies the components you have purchased. It also includes an "as-shipped" section. This is important as it lists exactly which version of RM-4 you have purchased and lists certain settings and defaults which may vary between models and serial numbers. - Page 10 This page intentionally left blank.

Save the original shipping box for the RM-4. This box has been designed to protect the RM-4 during shipping and should be used in the event that the RM-4 needs to be returned to the factory. Checking the As-Shipped Sheets The as-shipped sheet lists the serial numbers of the parts shipped, the exact hardware configuration and calibration constants associated with your hardware. - Page 12 This page intentionally left blank.

Page 13: User Guide
4 - User Guide User Guide Each section of the User guide covers an aspect of the operation of RM-4 requiring some depth and understanding. These sections are in no particular order. Overview of Functionality General The RM-4 Bridge multiplexer is used at repeater sites in digital telemetry networks to receive data from up to seven more distant sites and retransmit data to the central site via a 10Base-T Internet connection. -
Page 14: Packaging
GPS Backup Power Battery An RM-4 with GPS has a 7 mA$h, 3.3 V Lithium battery to provide backup to the RAM and real-time clock. The RAM stores the GPS almanac, ephemeris, and last position, to aid the engine in locating satellites when power is restored. -
Page 15: Figure 1: Rm-4 Front Panel
Figure 1: RM-4 Front Panel Rear Panel The rear panel of the RM-4 is used to make all of the necessary connections to the unit. Connections include Ethernet, GPS, Power, and Serial Ports 1 to 8, as shown in the figure below. -
Page 16: Remote Site Setup
Remote Site Setup Discussion The RM-4 is typically used to multiplex streams of data from digitisers onto a LAN. The data can come directly from an HRD or an Orion, or via modems, radios or satellite transceivers. Up to seven streams of data can be multiplexed by a single RM-4. -
Page 17: Internet Timeserver Setup
An RM-4 equipped with the optional GPS engine can be used as an Internet timeserver. The setup for this use of an RM-4 is shown below. Serial data streams can be accepted by the RM-4 in this configuration as well. -
Page 18: Field Deployment Procedure
4 - User Guide ports of the RM-4. The serial data stream is demultiplexed, then ported into the IP layer and transmitted to the NAQSServer in the form of UDP packets. Field Deployment Procedure Deployment The following steps are suggested to start up the RM-4 after the installation of the sensor and digitiser at the planned sites. -
Page 19: Configuring The Ethernet Port
Configuring the Ethernet Port Choosing IP Addresses Assigning the IP addresses to an RM-4 is important and must be based on the operation of the entire network. Before configuring any RM-4, obtain information on the range of available IP addresses and any operating firewalls and then carefully allocate the addresses of all of the RM-4s of the network. -
Page 20: Using External State-Of-Health Inputs
In general, bandwidth is most often limited by the radios or modems in a particular link. If, however, a link consists of a direct connection between digitiser and RM-4, then there is no reason not to use the maximum available baud rate, and reduce system latency even further. -
Page 21: Setting Up The Gps Antenna
The RM-4 supplies power to both the basic RM-4 and the GPS. Since the GPS alone consumes almost as much power as the rest of a standard RM-4, it is important to take advantage of GPS duty cycling at sites having restrictions on power consumption. As the RM-4 timeserver does not use the duty cycling feature, do not enable duty cycling when using the time server. -
Page 22: Rm-4 Timeserver Option
Use only the cable supplied with your RM-4 with +12V input option when connecting to the external power source. Although over-voltage and reverse voltage protection is provided within the RM-4, there is still a risk of damaging the unit if, for example, 12V is applied to the +5V pin of the power connector. -
Page 23: User Interface
RM-4 operation. To update the executable programs and the supporting files on an RM-4, a client can use the user interface to examine the file system on the RM-4 and then transfer the new version of a file to the RM-4. Usage and Options The RM-4 user interface consists of eight function buttons and three groups of tabbed pages for editing system configuration, monitoring system operation, and managing the RM-4 file system. -
Page 24: Figure 5: Logging On To The
After the RM-4 user interface has finished loading, click the “Log on” button to launch the “Log on” dialog box as illustrated in Figure 5. There are three levels of access to the RM-4 system: factory, tech, and user. A client can have tech or user access. With user status—the lowest access level—a client can access all the pages on system operation, and edit the user-access items in the... -
Page 25: Figure 6: System Soh
Figure 6: System SOH System The “System” page contains the internal and external state-of-health information of the RM-4, as illustrated in Figure 6. Click on the “Help on setting display...” button to toggle the help on setting display format and color. Click on a display field, e.g., the text field next to “Battery (Volt):”, to display on the right side the current display setting of the field. -
Page 26: User Interface
The new setting takes effect when a new “Request SOH” command is issued. If the setting is changed, the user will be prompted to save the change into the RM-4 configuration. A user can check all the display settings and make desired changes before saving all the changes to the configuration, i.e., saying “Yes”... -
Page 27: Figure 7: Quality Of Data Reception
The “GPS/Time” page (see Figure 8) contains the GPS operation status and the timing statistics of the RM-4 system during the most recent GPS cycle. The information displayed includes: Latitude current latitude of the RM-4 obtained from the last GPS query. +: north, -: south in degrees. Longitude current longitude of the RM-4 obtained from the last GPS query. -

4 for data port 6, the retransmit request is sent via port 4 to the digitiser connected to port 6. Note: The value of ReTx port for the default data port defines the port through which the RM-4 sends the retransmit requests for an unknown digitiser that is connected to a different RM-4. The value may vary from 0 to 7, where 0 means rejecting any retransmit request for an unknown digitiser. -

Destination Internet configuration A destination station is a remote computer to which the RM-4 server sends the time series data and SOH information through an Internet connection. The RM-4 also listens for any request from the remote computer, if the remote is running NAQSServer. -
Page 33: Figure 13: Configuration Of Access Privileges
The “Access” page (see Figure 13) contains the “log on” information for factory, tech, and user access levels. The information is used by the RM-4 when a client tries to access the system. Two fields are required for each level: Login The name of a user. -

These channels, along with three SCCs and one SMC of the PowerPC, comprise the eight external serial ports on the RM-4. All of these ports are equipped with RS-232 transceivers, and EMI suppression using ferrite beads. Surge protection is provided on all external serial connections using bi-directional transorbs which clamp external voltages at ±7.5 V. -

Using a digital multimeter, check the resistance of the fuse. This fuse will be located at F1 for a standard RM-4, or at F2 for an RM-4 which is configured for 12 V input. If the fuse appears as a short circuit (zero resistance) then the fuse is OK. -
