TIME CODE READER

Time Code Reader
  • Overview

Time Code Reader Unit is designed to read, check and transmit the Universal time (UT) and Count down Time (CDT) codes. It displays both UT and CDT information in dedicated Seven Segment LED display.

  • System Configuration

1. Then system can be operated in two modes:

  • I. IRIG mode

  • II. ETH mode

2. In IRIG mode, it reads and displays following signals:

  • I. Balanced

  • II. Unbalanced

  • III. DC code serial -TTL

  • IV. DC code Serial -EIA

3. In ETH mode, it reads and displays data packet based on Rotary switch user selections (optional, needed if more than 1 line of UT/CDT)

4. UT and CDT from any input mode is combined to an UDP Output

5. Code quality is checked for several Parameters and status is shown in OLED display

  • Indicators

1. IRIG and ETH source selection

2. MOD and DC selection

3. DC EIA and TTL selection

4. UT and CDT 1PPS MOD/DC Code

5. ETH mode SYS, UT and CDT selection

  • Controls and Outputs

1. Toggle switches for Source selection IRIG/ETH

2. Rotary switches to select – System 1/2/3, UT 1/2/3 and CDT 1/2/3 in Ethernet mode

3. BNC connectors for MOD code input and output

4. DC Input via RS232 connector

5. Variable Potentiometers for AGC adjustment for both UT and CDTFunctionalities

6. 1/10/100/1K PPS outputs through BNC

7. UT and CDT Serial Output through RS232 port

8. RJ45 connectors for Ethernet

  • Network

1. Two UDP ports for Input and Output through RJ45 10/100 Base T ports

2. Supports both UNICAST and MULTICAST

3. Ethernet ports, packet rates, system selection locations can be configured with the help of browser through UDP Output port

  • Specifications

1. Input UT Time IRIG-B

Time Code IRIG-B AM modulated code for Universal Time.
Input Level 500mVpp to 10Vpp
Input Impedance 10 K Ohms Minimum or suitable as per design for 50 Ohm BNC connector input cable
Input Connector Type BNC female connector for IRIG-B AM modulated code.

2. Input CDT Time(EIA)

Time Code Modified IRIG-B DC shifted code for Count Down/Up Time that supports Inverted or Non-Inverted code
Input Level Inverted Code (+12Vpp for’0′ bit-12Vppor ‘1’ bit)
Input Level Non-Inverted Code (- 12Vpp for’0′ bit+12Vppor ‘1’ bit)
Input Impedance 10 K Ohms Minimum or suitable as per design for 50 Ohm BNC connector input cable
Input Connector Type INNER JOIN borrowers ON statistics.borrowernumber=borrowers.borrowernumber

3. Input UT Time (NTP) or CDT Time over Ethernet

NTP over ethernet Unit displays UT Time coming as Ethernet packets i.e. standard NTP Time output given by Navic Receiver or GPS receiver
CDTover ethernet Unit displays CDT time through Ethernet packets (supports customized packets also)
InputConnectorType 2 separate RJ-45 Ethernet connector – one for NTP server IP another for CDT server IP

4. Configuration & Control of Unit

Connector Port 10/100Base-T RJ-45(Ethernet connector)
Configuration functions Configuration of Display Unit IP, in the Display Unit configuration of time server IP (NTP server IP and CDT server IP) from which it accepts time in the form of Ethernet packets.

5. Operating conditions

Inputpower supply IEC320C14 male power plug or 3 pin Circular Connector with power cord supporting 230V +/- 10% and 50 +/- 3Hz
Operating temperature 5 to 45 Deg. Celsius
Humidity Up-to 90% non-condensing

6. DisplayControl/Indications

UT Input Time Unit will display UT time coming either over separate BNC female connector (UT IRIG-B AM modulated) or over separate Ethernet connector(NTP packets for Navic Receiver or GPS Receiver)
CDT Input Time Unit will display CDT time coming either over separate BNC female connector(CDT EIA) or over separate Ethernet connector
UTTime Display Format Display of UT Time in 9 digit ultra bright (0.8 inch height & 0.4inch width) 7 segment display (format should be DOY HH MMSS) representing Days (3 digits), Hours (2 digits), Minutes (2digits) and Second (2digits), with clear gap between Days, Hours, Minutes and Seconds.
CDT Time Display Format The unit will display UT time and CDT time simultaneously. Display of CDT time in 6 digit ultra bright (0.8 inch height & 0.4 inch width) 7segment display (format HH MM SS) representing Hours (2digits), Minutes (2digits) and Seconds (2digits), preceded by alphanumeric sign display ‘+’ for Count Up, ‘-‘ for Count Down and ‘H’ for Hold with clear gap between Days, Hours, Minutes and Seconds or equivalent letter display ‘up’ for Count Up, ‘dn’ for Count Down and ‘ho’ for Hold.
Time Display LED color Bright RED
