VOCIA PAGING STATION INTERFACE 1 (VPSI-1)
Setup and Use
The Vocia software is used for configuring and programming the host device interfacing to the VPSI-1. The information supplied by this
manual relates to hardware installation, physical connections and device information. For more details on software setup, please consult
the Vocia Software Help File.
Installation
The VPSI-1 has mounting holes to facilitate discreet surface mount installation local to the external interfacing equipment.
Power
This will illuminate green when connected to the host device to indicate the device is receiving power.
To Host
The VPSI-1 is designed to connect directly to a Vocia Paging Station Auxiliary Port or a VI-6 Paging Port. The VPSI-1 has a female RJ-45
conector labelled ‘To Host’ to fascilitate this direct connection. A screened CAT5e or CAT6 cable wired straight through must be used,
up to a maximum of 100 foot (30 meter) distance. Unscreened cable must not be used. The VPSI-1 is not an IP device and must not be
connected to an Ethernet switch or network. It must be connected directly to either a Vocia Paging Station Auxiliary Port or a Vocia VI-6
Paging Port.
Audio In
A balanced audio input is available for paging audio. Input Level Jumper connections on the rear of the unit allow the input sensitivity to
be set. Four nominal levels are available: 0dBu, -10dBu, -40dBu and -50dBu. A three way jumper is provided that should be placed at the
required setting (fit one jumper only using long nose pliers; ensure that the jumper is correctly located on the 6-pin header).
RS-232 and LED Connector
The DB-9 connector can be configured for two modes of operation in the software, either as a RS-232 port to facilitate Paging Station
Vocia Text Protocol (PS-VTP) Interfacing or as an LED indication driver for an external interface board.
PTT
An external Push-to-Talk connector is provided. The PTT is active when shorted to ground.
