IP7-ST / STX

Getting Started Guide

Introduction

The IP7-ST/STx IP Intercom endpoint enables 2-way IP audio from an
analog call station with TalkMaster™ software and/or VoIP Systems
supporting industry standard SIP 2.0 (VoIP) protocols. Standard features
include, PoE/External Power, Dual Ethernet ports and Talk/Relay/Sensor
connections.

The ST(x) supports several types of call stations:

• PNL-CISx Single Transducer call stations. Single Transducer call stations
use a single speaker as both a speaker and as a microphone

• Aiphone™ LE / LS series 3-wire call station

• Aiphone™ IE / IF series 2-wire call station

• Call stations with a separate microphone, speaker and Call button

The ST(x) may also be used to drive an Analog Paging Amplifier.
The IP7-ST/STx is configured using TalkMaster Admin Console software.

This Getting Started booklet covers basic hardware installation and software
configuration of the IP7-ST/STx.

IP7-ST/STX Installation

Important Installation Guidelines

• Use 18-20 AWG shielded, twisted wire for microphone signals

• Use 18 AWG wire for speaker and signaling connections.

• Avoid sharing AC power and audio in conduit runs

• Do not install near power distribution equipment or noise generating

equipment such as stepper motors

• Conform to industry standard practices for grounding

Twisted Shielded

Sensor Input (Optional)

2 Conductor Wire

(No Connection)

• Set the internal ST-MIC switch
to the ST setting

• Connect SPKR 8Ω+ and SPKR
8Ω- (J2-6 and J2-7) to the

speaker terminals on the call
station (polarity independent)

• Connect TALK (J2-5) to one

contact on the call station’s

TALK button

• Jumper the remaining contact
on the call station’s TALK button
to one of the speaker terminals (this wire should be limited to 10ft or 3
meters)

• Connect GND (J2-4) to the shield of the shielded wire. Do not connect the
shield at the door station

Please refer to the IP7-ST/STx Reference Manual available on the Software
Installation CD for additional information on installation and setup

Aiphone™ LE / LS series 3-wire Call Station Installation

• Set the internal ST-MIC switch to the ST
setting

• Remove Aiphone shorting link between
E and - terminals

• Connect SPKR 8Ω+ and SPKR 8Ω- (J2-
6 and J2-7) to the “1” and “E” terminals
on the Aiphone call station

• Connect TALK (J2-5) to Aiphone “–“
(minus) terminal

• Connect GND (J2-4) to the shield of the shielded wire. Do not connect the
shield at the call station

Aiphone™ IE / IF series 2-wire Call Station Installation

• Set the internal ST-MIC switch to the
MIC setting

• Connect GND and TALK (J2-4, J2-5)
to Aiphone terminals 1 and 2 (polarity
independent)

• Connect GND (J2-4) to the shield of
the shielded wire. Do not connect the
shield at the door station

Call stations with a separate microphone, speaker and Call button

• Set the internal ST-MIC switch to the MIC setting

• Connect MIC+ and MIC- (J2-1, j2-2) to

the call stations microphone

• Connect GND (J2-4) to the shield of
the shielded wire. Do not connect the
shield at the call station

• Connect SPKR 8Ω+ and SPKR 8Ω-
(J2-6 and J2-7) to the call stations
speaker terminals

• Connect TALK (J2-5) to one contact
on the call station’s TALK button

• Connect the other contact on the call station’s TALK button to GND (J2-4)
or jumper it to one of the speaker terminals (this wire should be limited to
10ft or 3 meters)

Driving an Analog Paging Amplifier

The IP7-ST/STX has the capability to drive a balanced 600 Ohm input of an
analog amplifier using SPKR 8Ω+ and SPKR 8Ω- (J2-6 and J2-7). Set the
IP7’s volume level to 6 and adjust the amplifier’s volume control accordingly.

If the analog amplifier uses an unbalanced input, then the IP7’s Line
Out and GND (J2-3 and J2-4) must be used instead of SPKR 8Ω+
and SPKR 8Ω-. Failure to do so will damage the IP7 and void its

warranty.

Relay Options

• The integrated Relay uses COMMON (J3-2), along with NO - Normally
Open (J3-1) or NC - Normally Closed (J3-3). Use Admin Console to
configure the options

Sensor Options

• The integrated Sensor can be used to monitor the status of a door by
connecting Sensor (J3-5) and GND (J3-6) to a contact closure sense
switch. Use Admin Console to configure the options

Power Options

• Power over Ethernet (PoE - 802.3af compliant) - requires 7 watts from
Power Source Equipment (PSE)

• 9VDC - 32VDC external via J1-1 and J1-2 connectors or Aux Power

2.1mm barrel connector

• An external power supply, if detected, overrides PoE power

Network Installation

• Connect an RJ-45 cable between the Ethernet 10/100 connector and a
10/100 network switch

• On the IP7-STx, after the Ethernet 10/100 is connected, another IP device
can be connected to Port 2 10/100 jack

Mounting Instructions

The IP7 series is design to be mounted on standard 35mm DIN rail or
surface mounted using the surface mounting plate.

• DIN Rail Clip – Tilt top of unit (J1, J2, J3 connectors facing up with Volume
buttons facing forward) back towards the DIN Rail until the IP7 DIN clip
catches the top of the rail. Press in at the bottom of the IP7 to snap into
place

• Surface Mount Plate – Snap the surface mount plate in half and secure it
to the back of the unit using the provided screws so that the mounting
holes extend past the edges of the case
