DS-4 bOttOM View
This connection carries control data, power, and digital audio over CobraNet. PoE-enabled network switches or PoE midspan adapters
must be used to power the DS-4. These must be 802.3af compliant. The maximum distance between any unit and an Ethernet switch is
328 feet (100 meters) when using copper cabling. Additional Ethernet switches and/or fiber-optic cable can be used to further extend
distances between units on a network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions) within
a network.
If other network traffic shares an Ethernet switch with the Vocia network, a managed switch should be used with separate VLANs.
The following diagrams illustrate valid network connections for the DS-4.
Personal Identification Number (PIN) Security
The DS-4 can be configured for PIN security protection. If PIN security is enabled via the Vocia software, the four Page Code buttons may
be used to enter the required four-digit PIN (see button labeling examples below). To enter a number, the user may need to press a button
multiple times (as in SMS messaging). During PIN entry, the two “Next” and “Previous” soft key buttons on the right side of the display will
display as “Clear” and “Enter” respectively. Input the four-digit PIN sequentially, followed by the “Enter” key or the Push-to-Talk button.
Each digit will be shown briefly on the display and subsequently replaced by an asterisk for security purposes. If the entered PIN is correct,
the station will unlock and be ready for use.
After a period of inactivity (no pages made and no buttons pressed), the DS-4 will revert back to a locked state. This length of time
(at a default of 180 seconds) is set using the Vocia software. To lock the station instantly, the user can press and hold down the “Next”
and “Previous” buttons at the same time.
