Power Indicator
Due to potential energy hazard, connections to the Auxiliary Power 24V DC inputs must be made by a qualified electrician or other
The Vocia PSKIT-1 is capable of operation from both PoE and 24V DC power. If both are being used,
PoE power is given priority. The Power Indicator LED behaves in the following manner:

CONNECTIONS
Power
The PSKIT-1 supports powering via 802.3af or 802.3at (Type 1) PoE switches or external PoE Supplies.
Alternatively the device can be powered using the Power connector and an external 24V DC supply. Both
supplies can be connected at the same time without affecting the unit. Upon loss of one power source the
unit automatically switches to the other source without interrupting device operation.
Microphone
A microphone may be connected using the external 3-pin balanced microphone input provided. The
default nominal input level is -50dBu. Phantom power is not available on this input. If using this input, the
microphone and its connection will not be monitored.
The PSKIT-1 also includes a 5-pin internal connector for supporting a Biamp monitored microphone
(optional accessory). This connection is not accessible from the outside of the enclosure and must only
be used with a Biamp supplied microphone. If the internal connector is being used with a monitored
microphone, the LK1 and LK2 jumpers must be removed. By default the jumpers are installed, which
disables the monitoring functionality so that a standard (3-pin) microphone may be used.
Do not use both the internal and external microphone connections at the same time.
PTT Input
The Push-to-Talk function will be activated when the PTT pin is connected to Ground.
General Purpose Inputs
The PSKIT-1 supports 12 unmonitored Control Inputs for connection to a keypad interface numbered 0
through 9, as well as inputs for a Next and Previous scroll button. Each Control Input is activated with a
momentary connection to Ground. Only one pin can be selected at once.
General Purpose Outputs
Two General Purpose Outputs are used to indicate the Wait and Talk states.
Once the PTT is active the "Wait" output will assert while the system establishes the necessary audio
paths, checks for zone availability
and plays the chime (if selected). The "Talk" output will assert once the audio path is live.
RS-232
A female RS-232 serial port is provided for Vocia Text Protocol (VTP) connectivity. Please refer to the
software help file for all supported
commands.
