Valcom’s V-GPS-TX Wireless Master Clock receives accurate time updates via GPS satellites and interfaces directly with Valcom’s Analog and Digital Clock Systems.

• Up to 10 server addresses can be pre-programmed into the unit for continuous, accurate synchronization (with web interface software upgrade)
• Extremely intuitive GUI that allows user to configure all of the settings of the master clock through a simple web interface
• Automatic bi-annual daylight savings time changes (when used as a primary master clock)
• Ten-year battery backup for timekeeping

The Valcom V-VCU, 2-Wire Clock Driver corrects Valcom analog and digital display clocks over a single pair of UTP cable. Time may be adjusted to update from once every second to once an hour.

• Provides power and data for Valcom 2-Wire Clock connection over a single par of wires
• User selectable correction intervals
• Data error LED indicators
• Power/data output LED indicators

The Valcom VIP-MC, IP Master Clock is designed to provide clock synchronization signals to Valcom and other manufacturers’ clocks. IP network device signals include Network Time Protocol (NTP) and Daytime protocol. Analog (wired) correction signals include 2-wire Digital Correction, 2-wire BCD Correction, and many relay-controlled corrections. Relays not used for clock correction may be programmed to activate on a schedule. Up to 100 entries may be entered, such as triggering external tone generators, opening doors, and others.

• Acquires time from any NTP server over the IP
• Network or date and time can be manually set
• Provides time to NTP clients and/or Daytime
• Protocol clients
• Programmable via web browser, Valcom VIP-102B
• Very high-precision internal Real Time Clock
• Provides 2-wire Digital correction, 2-wire BCD
• Correction and over 16 Relay correction formats
• Four Form C relay outputs
• Two Contact Closure inputs
• Power over Ethernet (PoE) 802.3af compatible
• DC power input jack for non-PoE installations
• Each relay may be scheduled for up to 100 events per day to activate external equipment

Valcom’s V-WMCA, Wireless Master Clock Transceiver provides a single time standard for wireless clocks. The V-WMCA features browser-based setup eliminating the need for resident software.

• Can act as a transmitter or repeater for Valcom Wireless Clock Systems
• TCP/IP network connection
• Frequency tuning circuit allows for time correction with changes in temperature.
• Field-enabled Daylight Savings Time (When used as a primary master clock)
• Can act as an interface between existing systems to Valcom Wireless Systems

The V-WMCRA Wireless Master Clock Repeater extends the range of correction signal to more clocks
in your organization. The Wireless Master Clock Repeater has dual use that can be used as a repeater
or with additional equipment, and as a transmitter.

The V-WMCRA is not a stand alone wireless master clock. It must be used with a V-DCPI Digital Clock Protocol Interface, a V-GPSA, GPS Receiver or a V-WMCA Wireless Master Clock.

• Transmits wireless clock correction signal to the Valcom Wireless Clocks
• 915 – 928 MHz frequency-hopping technology
• Can transmit up to 2000 meters in open space
• Wirelessly receives & transmits data
