Overview

The device described in the manual is the BS330 base station, a component of a DCT1800-GAP cordless system. It functions as a radio transceiver, connecting to a radio exchange via a standard twisted pair cable. The base station can be mounted in various locations, including walls, ceilings, poles, or beams, using an included mounting bracket. For pole or beam mounting, a separate strap or flexible metal band (not included) is required.

Function Description:

The BS330 base station facilitates wireless communication within the cordless system. It receives power and data from the radio exchange through its RJ45 connectors. The base station's operational status and traffic activity are indicated by two LEDs: LED 1 (Green power LED) and LED 2 (Three-colour LED). LED 2 provides detailed status information:

  • Off: Base station operational, no traffic.
  • Green: Base station operational, traffic.
  • Red: Base station malfunctioning.
  • Amber: Base station OK, but not available (self-test, not initialized, no communication with radio exchange).
  • Flashing green: All 8 channels are in use.
  • Flashing amber: Software is being downloaded.

The base station's software can be updated by downloading new software, which is stored in flash memory. This process can be performed without disconnecting the base stations, using the Cordless System Manager (CSM) for Windows.

Important Technical Specifications:

The BS330 base station comes in several versions, each operating within a specific frequency range:

  • BS330/STD: 1880-1900 MHz
  • BS330/CHINA: 1900-1920 MHz
  • BS330/LA: 1910-1930 MHz
  • BS330/US&CDA: 1920-1930 MHz

Connectors:

  • Two 8-pin RJ45 modular jacks: For data and powering. These connectors are interconnected on the board.
  • One 6-pin RJ12 modular jack: For factory testing.

Power Distribution:

The base station can be powered by:

  • The radio exchange via the data pairs.
  • The radio exchange via the data and Express Powering Pairs (EPP).
  • A 48 V external supply connected to the radio exchange.
  • A local AC-adapter (BMLNB 101 09/n), which is a 24 Vdc adapter with an 8-pin RJ45 plug that connects to one of the data/power connectors.

It is crucial not to power the base station via the EPP terminals from a local power source and the radio exchange simultaneously, as this would interconnect the two power sources. However, simultaneous powering via data pairs from the radio exchange and a local power source is permissible due to an internal rectifier. The power inlet of the base station (EPP) is insensitive to polarity reversals.

Cabling:

The base station cable must be a twisted pair cable with a minimum of 2 pairs for data lines. Power can also be distributed via these data pairs. A three-pair cable can be used for additional EPP wires to extend the distance between the base station and radio exchange. Data lines of the same twisted pair (e.g., SC0-a and SC0-b) can be interchanged, and the EPP pair is insensitive to polarity reversal. Data pairs themselves should not be interchanged.

Usage Features:

Installation:

Base stations can be mounted vertically or horizontally. When mounting, ensure the base station is not facing large metal objects like heating pipes.

Mounting Bracket Installation:

  1. To a wall: Hold the bracket flat against the wall with the "TOP" text facing up. Mark the two holes. Ensure a minimum distance of 65 mm between the upper hole and the ceiling or any object above to allow the base station to slide onto the bracket. Drill Ø 6 mm holes for wall plugs (included) and fasten the bracket with Ø 3.5 mm screws (included).
  2. To a ceiling: Similar to wall mounting, but ensure the front of the base station points downwards if positioned above a suspended ceiling.
  3. To a pole or beam: For poles (diameter ≥ 45 mm) or beams (wider than 50 mm), use a locally purchased strap or flexible metal band (less than 30 mm wide). Fix the bracket with the "TOP" text facing up.

Cable Management:

When wall-mounted, cable ducts can be used to route wiring. Minimum distances between cable ducts and the mounting bracket are specified (e.g., 57 mm from the top of the bracket to the top of the duct, 65 mm from the top of the bracket to the ceiling, 75 mm from the side of the bracket to the side of the duct, 125 mm from the bottom of the bracket to the bottom of the duct).

Cable Securing:

For safety, secure the base station cable approximately 30 cm from the base station to prevent it from being pulled out if the base station drops.

Connecting the Base Station Plug:

Cut the base station cable to the correct length and connect it to an RJ45 modular jack. If cables need to enter centrally from above, guide them through the recess in the middle of the base station. Plug the data cable's modular jack into one of the data/power connectors. If using an AC-adapter, plug its modular jack into a data/power connector and the AC-adapter into a wall outlet.

Mounting the Base Station:

Hold the base station flat against the mounting bracket and slide it downwards until it clicks into place.

Initialization:

After installation, base stations must be initialized using the cordless system manager.

Maintenance Features:

Cable Delay Measurement:

This is necessary when the base station is connected to specific CLU or SLU boards (REX-BRD0014, REX-BRD0015, or REX-BRD0026 with revision lower than R2A). After all base stations are installed, cable delays must be measured to program them into the system at initialization.

  1. Ensure the base station cable is unplugged from the base station.
  2. Disconnect the relevant connector from the CLU, CLU-S, or SLU.
  3. Connect an echo-meter to cable pair SC0 or SC1.
  4. Measure the cable delay. The recorded value (time between sending a pulse and receiving the echo) is twice the actual cable delay, so it must be halved. The resulting value needs an accuracy of 200 ns (corresponding to 20-30 m).
  5. Record the delay value in microseconds for each base station, along with its number.
  6. Repeat for all base stations connected to the CLU, CLU-S, or SLU.
  7. Reconnect the connectors to the CLU, CLU-S, or SLU.
  8. Repeat for base stations connected to other CLUs and SLUs if applicable.

Branding:

Brand labels are not included in the box and must be ordered separately. They are to be stuck in the front cover recess of the base station.
