Connections

satSite 142

Note: The "B" interface, the one set for DHCP, is always the one closer to the antenna port.

Mounting the SatSite on the tower

Note: Tower work is dangerous. Do not attempt to climb a tower without proper equipment and training.

Each SatSite is provided with a pair of mounting brackets. These are different for 142 , 132 and high-temperature ("142T") versions.

SatSite 142

Each mounting bracket has

• a flat or U-shaped plate that attaches to the SatSite radiator
• a set of 3 bridles for different sizes of poles
• a set of bolts and nuts and washers for assembly

Please refer to the image Mounting Brackets SatSite 142 for details.

SatSite 142T (high-temperature)

Please refer to the image Mounting Brackets SatSite 142T for details.

Note the extra nylon spacers between the flat plate and the radiator.

SatSite 132

The SatSite 132 mounting kit has 2 bridles that fit pole sizes of 35 - 85 mm.

These bridles fit onto 4 M6 threaded rods that screw into mounting holes on the back of the unit.

Please refer to the guide Mounting SatSite 123

Power supply

The SatSite operates from -48 VDC. The input is diode-protected against reverse voltage.

The unit is supplied with a 10-meter power cable and an extra connector so that you can make your own cable following the information below.

The unit is supplied with a 200W 48VDC supply that can be used to power it from mains power of 120-240 VAC, 50-60 Hz.

Power supply cables

SatSite

• positive (supply ground, "V+") = brown cable
• negative (-48 VDC, "V-") = black and grey cables
• safety ground (G) = green + yellow cable

Mains/Grid

• mains neutral = blue
• mains 120-240 VAC 50-60 Hz ("hot" or "live") = brown
• safety ground = yellow + green

Grounding

The installation kit includes a grounding strap that should be attached from the radiator (142) or mounting bracket bolts (132) to a sufficient ground point.

The SatSite installation kit includes a lightning arrestor. For this arrestor to be effective, the SatSite unit case must be properly grounded.

For a conductive metal mast, grounding is achieved in three steps:

1. The grounding strap must be firmly attached to the mast, with good electrical contact.
2. The mast itself must be properly grounded. The requirements and techniques for grounding vary with local factors, like soil composition and construction regulations.
3. The power supply system that feeds the mast must be properly grounded.

Note: The maximum allowed resistance between the SatSite unit and ground is 4 ohms.

Note: The design of grounding systems is site-specific. Please consult a local electrician for a proper grounding system for your site.

Ethernet

The Satsite has two Ethernet connectors for Network A and Network B.

By design Network B is the port closer to the Antenna

• Network A has the fixed IP 10.0.3.1
• Network B will have DHCP IP address

Note: We recommend installing both network cables to the SatSite unit, so that the "A" port can be used to recover the unit if DHCP fails.

Thread the shroud onto the ethernet cable.

Attach and crimp the R5-45 connector onto the cable in the standard way.

For this step, you need two 19 mm wrenches. Slide the shroud over the connector.

The connector will slide completely into the shrowd, further than shown here. Then tighten the gland nut around the cable. When attaching the cable to the SatSite unit, align the connector first, then press it into place, then turn the shroud body to lock the connector. Also check the gland nut is tight and forms a good seal.

RF cable and antenna

Before attaching the antenna cable, install the supplied lightning arrestor on the antenna connector. The connect the antenna cable. When a SatSite unit is powered, the output can be as high as 20 watts RMS, enough power to cause burns if you come into direct contact with the central conductor of an RF connector. Use caution and avoid working with actively powered radio equipment.

The arrestor and RF cable must be installed carefully. Its recommended to use spanner 14 mm while connecting the cable to prevent rotation of the connector.

Getting started

In order to get started with Satsite , you can either use the static IP or dynamic IP.

1. Using static IP Connect Network A ethernet to PC , and assign the PC static IP address in the network 10.0.3.x /8 Then you can access it via ssh

• ssh yatebts@10.0.3.1 -p 54321
• then telnet 0 5037

or via the web interface http://10.0.3.1:2080/lmi The username is yatebts and the password is the serial number

2. Using dynamic IP Connect Network B to your local network and make sure it get DHCP IP address. You can find the assigned IP following the guide: Finding DCHP IP address Then you can access it via ssh

• ssh yatebts@<DHCP_IP_ADDRESS> -p 54321
• then telnet 0 5037

or via the web interface http://<DHCP_IP_ADDRESS>:2080/lmi The username is yatebts and the password is the serial number
