product

Product Information

The SecureSync 2400 Master Clock is a versatile electronic device designed for defense and electronics applications. It offers precise timekeeping and synchronization capabilities, ensuring accurate timekeeping across various systems and networks.

Form Factor Options

2406-XYZ: Features six option card slots
2402-XYZ: Features two option card slots

Backup Oscillator Options

240W-XYZ:
- 0 = TCXO (Temperature-Compensated Crystal Oscillator)
- 1 = OCXO (Oven-Controlled Crystal Oscillator)
- 2 = OCXO LPN (Low Phase Noise Oven-Controlled Crystal Oscillator)
- 3 = Rubidium
- 4 = Rub LPN (Rubidium Low Phase Noise)

Accuracy and Holdover
The SecureSync 2400 Master Clock offers accuracy to UTC (locked to GPS) at 1 sigma. It also provides holdover stability, maintaining consistent timekeeping even after 2 weeks of GPS lock, with specified accuracy after 4 hours and 24 hours.

Power Options
The SecureSync 2400 can be powered using two different configurations:

Single Fixed Power 240W-XYZ:
- X options: 0 = 100-240 VAC, 3 = 12 VDC, 4 = 24/48 VDC
Hot Swap Power 240W-6YZ:
- Requires at least one power module in addition to the base unit
- Power module options: 2400-HS-A1 = 100-240VAC, 2400-HS-D1 = 12 VDC, 2400-HS-D2 = 24/48 VDC

I/O Options
The SecureSync 2400 supports network expansion and connectivity through optional I/O cards:

1204-49 Dual Nic Option Card (SFP): Provides NTP-only ports
1204-4A Quad Nic Option Card (SFP): Provides NTP-only ports

NENA Compliance
To meet NENA Master Clock specifications and synchronize legacy Spectracom TimeView Display Clocks over RS-485 Terminal Block, the following options can be added:

SFP-Copper Module(s)
CA08R-0000-0010 NENA Breakout Cable
1204-0F Alarm Relay Option Card: Enables Relay/Alarm OUT (Terminal Block) (Requires 1204-0F installed)

Accessories
Various accessories can be added to enhance the functionality of the SecureSync 2400 Master Clock.

Product Usage Instructions

To use the SecureSync 2400 Master Clock, follow these steps:

Choose the desired form factor option based on the number of option card slots required.
Select the appropriate backup oscillator option based on your needs.
Build the power configuration by either opting for Single Fixed Power or Hot Swap Power. For Single Fixed Power, populate the X with the desired power option. For Hot Swap Power, order at least one power module in addition to the base unit.
If network expansion is required, select the desired I/O option card(s) based on your connectivity needs.
If NENA compliance is necessary, order the SFP-Copper Module(s), CA08R-0000-0010 NENA Breakout Cable, and/or 1204-0F Alarm Relay Option Card.
Add any desired accessories to enhance the functionality of the SecureSync 2400 Master Clock.

For more detailed setup information on specific options, please refer to the SecureSync2400_NetClock_Option_Guide_rev1 document.

Build the Power

Single Fixed Power
240W-XYZ

Populate the X with the a power option below:

0 = 100-240 VAC
3 = 12 VDC
4 = 24/48 VDC

Integral power supply, ships with line cord or mating connector

Hot Swap Power
240W-6YZ

Dual Hot-Swap requires ordering at least one power module, on top of power option 6 for the base unit. Order (1) or (2) of the these power supply line items with the base unit, in any combination:

2400-HS-A1 = 100-240VAC
2400-HS-D1 = 12 VDC
2400-HS-D2 = 24/48 VDC

Pick the I/O

Expand Network Capacity

Order Option Card(s)

2400 includes two Gbe Network ports on chassis (1) RJ-45, (1) SFP.
Add additional network cards to increase processing capacity and the number of ports from 2 (Base) to 4, 6, 8, or 10 network ports in a single 1RU chassis.
The ethernet ports of the base chassis unit provide NTP, PTP, and Management capabilities.
Field upgradeable.
