Cell Sync Installation
How to install the Cell Sync receiver and software
Step-by-Step Installation
Software Installation
Connecting Receiver
Quick Start
  1. Install the Cell Sync software and CDMA receiver hardware.
    Connect CDMA receiver to the computer's serial port. Plug in power.
  2. Open up the CDMA Setup screen in Cell Sync
    Select the number of the serial port connected to the CDMA receiver
  3. Select the model of CDMA receiver in use from the pull-down and press 'Reset'
    Other options are automatically set once you select the model.
  4. Open the CDMA Test screen, press the Open button
    The CDMA receiver data should now be visible in the data window.
  5. Wait till the CDMA receiver is synchronized with the cellular transmitter.
    This normally happens within a minute or two when reception is good.
  6. Check "Enable CDMA as time base" on the CDMA Option tab
    This sets ClockWatch to use the CDMA receiver as a time base
Step-by-Step Installation Instructions
 
Hardware Installation

1 Assembly

Unpack the receiver, antenna, data cable and power supply. Locate the Cell Sync CD-ROM. Screw the antenna into the gold colored connector, screw the power supply into the silver connector. Plug the 15 pin plug into the D-shaped connector.


Antenna, data and power supply connectors

 

2 Position the Receiver

Locate the receiver indoors away from computers and monitors ideally near a window.  Final receiver positioning should be done during the software receiver test. More...

3 Plug in the Power Supply

The receiver gets its power from the external universal power supply (included).  The red 'PWR' LED should light when the receiver is powered. When receiving the CDMA signals the 'LS' light will blink approximately once every second. Validation begins as soon as the unit is powered. More...

4 Connect the Receiver to Computer

Connect the receiver to the computer's serial port using the included DB-9 connector at the end of the data cable.  More...

Software Installation

Install the Cell Sync Software

Install the Cell Sync software from the CD-ROM, follow the menu to install ClockWatch>Cell Sync.

6 Configure the Receiver in Cell Sync

Open the ClockWatch program. Open the CDMA Setup screen (Options>CDMA>Setup). Select the CDMA Model (Multitech CDMA) and select the number of the COM port where the receiver is installed.

7 Test the Receiver in Cell Sync

Open the CDMA Test screen (Options>CDMA>Test). Open the connection and observe the data coming from the receiver. Time signal  validation begins as soon as the receiver is powered and is done independently from the Cell Sync software.

8 Set Cell Sync to use CDMA as Time Source

Set Cell Sync to use the CDMA receiver by ‘Enable CDMA as time source’ (Options>CDMA).  Set the interval (in minutes) how often Cell Sync will check time.  Close the Options, Setup and Test screens.

9Monitor the Receiver from Cell Sync

You can monitor the validation progress and time signal reception from the log window on the main screen of Cell Sync.

 
Start the Service in Windows
(optional)

After Cell Sync verifies that the computer has been synchronized the ClockWatch Service can be started and run to keep the computer synchronized. This service runs whenever the computer is on and the Cell Sync application need only be run to change settings.

 

Receiver Installation

Receiver Location
The antenna/receiver unit is designed to be used indoors installed on a desktop or mounted on a wall. Operation deep inside metal buildings or buildings with metal reinforcements may be marginal.

 


Mounting ears (included) permit wall mounting
 

Noise Sources
Avoid locating near suspected interference sources such as: Lamp dimmers, Fluorescent lamps, Electronic igniters, CRT monitors, Battery chargers, Switching power supplies, Motors, Automobile ignition systems, Power lines, Nearby Cell transmitters
Note: Interference is diminished by the square of the distance (i.e., doubling the distance from the source will reduce its effect by 4).

 

Broadcast  Reception
In some areas of the country the CDMA service may not be available. Check  to see if Sprint or Verizon has cell phone service in the area.

Data Cabling
The recommended cable type is RS-232.

Serial Cable Length Limits (RS-232)
Table below lists the maximum permissible cable lengths for various protocols  at various  representative data rates. These lengths are as specified in the EIA RS232C, CCITT V.55 and RS422 interface standards.


Material requirements:

  •  Conductor size and type: 24 AWG, twisted pair.

  • Nominal capacitance: 15.5 picofarads per foot (between
    conductors of each pair); 27.5 picofarads per foot (from each conductor to shield).

  • Nominal DC resistance (each conductor): 24.0 ohms per 1000 feet.

  • Nominal DC resistance (shield): 2.35 ohms per 1000 feet.

  • Shield type: Overall braided with drain wire.


Note on RS-232 Serial Cables: 
At lower peripheral speeds of up to 9600 baud, serial interfaces can usually operate over cables up to 100 feet long. Use of special high quality cable may in some cases allow this limit to be extended to as much as 200 feet.

Connecting Cell Receiver to Computer

Plug the data cable from the  CDMA receiver into the computer’s serial port. The data cable  has a female DB-9 connector at the end and plugs into an available serial port (usually named COM1 or COM2) on the computer.

Power Supply
  • The receiver gets its power from an external 100-240 VAC power supply (included)
  • The external power supply keeps the receiver active during computer downtime and reboots.
  • Re-validation of the time signal  begins as soon as the receiver is powered.
  • To  reset receiver and force a re-validation: remove power supply  from power supply or receiver, then reconnect.
