Page 20: Ssu-2000E Control Languages
SSU-2000e Control Languages Software embedded in the SSU-2000e hardware allows operators to query and manage an SSU-2000e from a local or remote management terminal using one of three control interfaces. These management agents allow operators to change factory default settings, set or restore stored configuration settings, configure and provision the SSU-2000e to meet the requirements of a unique environment, and perform maintenance and troubleshooting.

If there is no such error, the unit uses the stored position. The SSU-2000e generates an event when the GPS module calculates a new position, and stores the new position in NVRAM as the current position and changes the engine mode to fixed position.
Page 65: Retrieve Header
This command allows you to verify that the SSU-2000e is connected to the computer or network. It may also be used to retrieve the unit name (sid) and date and time. The only action taken by the SSU-2000e is to respond with the complied message.

Status, on page 83, and Parameters, on page 141, respectively. SNMP Protocol This section describes the two versions of SNMP that the SSU-2000e supports. The Communications module software determines the version of SNMP used by the SSU-2000e. See Table 4-1 for the part number for the various software loads that are available.
Page 238: Snmp V3 Details
SSU-2000e system, its modules, module features, input ports, output ports, etc. and variables include settings and measurements. The MIB is controlled by the SSU-2000e’s SNMP agent. The SNMP agent is a server program that sends SSU-2000e status (stored in the MIB database) to the network manager when the manager transmits commands.

254 Antenna Connection Overview The SSU-2000e chassis has two antenna connections located on the rear panel. The antenna connections are made via isolated TNC connectors J6 and J7, labeled ANTENNA-A and ANTENNA-B, respectively. The connectors are DC isolated and AC bypassed to frame ground.
Page 252 Follow local building electrical codes for grounding using the frame ground lugs on the SSU-2000e chassis. The in-line amplifier receives 5 VDC power from the GPS radio receiver, and is supplied on the center conductor of the LMR-400 or equivalent coaxial cable.
Page 253 Chapter 5 Antennas Installing Antennas Recommendation: Symmetricom recommends that you consider the following location and environment influences before installing the GPS antenna: If possible, provide the antenna with an unobstructed 360-degree view of the sky from the horizon. In general, do not allow obstructions that obscure the horizon (as...
Page 254: Antenna Installation Tools And Materials
Connect transient eliminators, if part of the grounding scheme, to earth ground through a conductor. Symmetricom makes no recommendation as to whether to install transient eliminators. Symmetricom can provide suitable transient eliminators as an option. Note: connect the outside transient eliminator ground to the Do not inside equipment rack ground.
Page 255: Cutting Antenna Cables
GPS antenna and the radio receiver. Coiling the excess cable also allows you to use the factory-installed crimped connector. Symmetricom does not recommend cutting the antenna cables provided in the GPS Antenna Kits. If you must cut the cables, please ensure that the following requirements are met.
Page 256: Connecting The Cable To The Antenna
If at all possible, avoid bundling the coaxial cable with other cables (and possible noise sources). Use appropriate cable-pulling devices when pulling the coaxial cable through conduit or a weather head. 256 SSU-2000e Technical Reference 12713140-003-2 Revision E.01 – January 2007...
Page 257: Installing The Transient Eliminator
4. Connect the ground wire between the transient eliminator and the proper grounding zone (building ground, master ground bar, or other) for the mounting location. Recommendation: Symmetricom does not recommend soldered connections for grounding purposes. All grounding connections should be secured with mechanical clamp connectors.
Page 258: Installing The Antenna Cable
2. Secure the free end of the antenna cable to the appropriate antenna connector on the rear panel of the SSU-2000e using the right angle adapter provided with the antenna cable. Recommendation: Symmetricom recommends coiling excess cable to avoid gain mismatch between the GPS antenna and the SSU-2000e.
