CHAPTER 1
Overview
The IP-223 Remote Adapter Panel provides a reliable means of remotely controlling two (2) audio devices. The adapter has
multiple modes allowing it to connect to both digital and analog consoles, and performs a variety of other tasks related to
putting radios on a digital network.
The IP-223 is interconnected to the distant remote control console(s) by means of any available WAN (Wide Area Network) or
LAN (Local Area Network) connection.
Operating Modes
The IP-223 is capable of operating each audio port in different modes:
Local Mode – The radio is connected directly to the IP-223 allowing for simple migration and local control of the radio.
Tone Mode – The IP-223, based on Ethernet traffic, generates the keytones required to control standard industry tone-
equipped radio circuits. This allows an existing tone decoder and radio to be connected. This mode also supports a parallel
analog console.
FIGURE 76. Local and Tone Mode Connections

Overview
14
Console Mode – Allows the use of existing tone-based consoles. The IP-223 decodes industry standard tones, converts it
to Ethernet traffic to another IP-223 that can be in tone or local mode.
Phone Mode – Using a PIB (Phone Interface Box) or TDI (Telephone Dispatch Interface), a line on the IP-
223 is used to connect to an analog phone line.
iDen Radio Mode – Using the NI-223, allows interface with a Falcon Class PTT (Push-To-Talk) mobile phone
system.
TETRA Radio Mode – Used to interface to a TETRA digital trunked system using the IP-223 and the Sepura
SRM2000 mobile radio. The IP-223 interfaces the radio through the PEI (Peripheral
Equipment Interface) allowing dispatch access to TETRA radio assets.
Features
NOTE: The features listed below for the IP-223 version 4.100 do not comprise the full feature set. For more information
on all the features available, contact Radio Dispatch Sales listed on www.telex.com
.

Operating Modes
NOTE: Transient protection is provided near all audio inputs and outputs. The IP-223 line transformers are not designed
to operate on lines carrying DC (direct current). If a voltage is on the line, isolate with external capacitors. If the
line termination must conduct direct current, install a 600:600 Ohm transformer designed for the current
involved.
IP-223 Accessories

NOTE: Radio 1 and radio 2 are also referred to as line 1 and line 2 in this manual.
Handset Jack
An optional handset is available for the IP-223. When the optional handset is plugged into the handset jack, the ability to
monitor and talk on either line is available. The handset jack is located on the front of the unit, see Figure 78. When the
handset PTT switch is pressed, the selected radio connected to the IP-223 is keyed up on the existing frequency and the
handset microphone audio is transmitted.
Ethernet audio is also generated on the TX multicast and port for the selected line. This functionality can be used to test both
the Ethernet network and the analog connection.
IC Button
The IC button, when pressed, sends audio from the handset microphone back through the IP Network on the selected TX
multicast and port. It also sends audio to the transmit lines of the IP-223 without keying up the radio. This means no PTT relay
in local mode and no EIA (Electronic Industries Association) tones in tone mode.
NOTE: A handset is required to use the IC button.
LCD Display
The LCD display provides panel status information, such as the IP and subnet addresses, line status, and handset line selection.
•TX F# (# is the selected function tone) indicates a PTT is active.
•RX F# (# is the selected function tone) indicates the RX radio is active.
•ID # displays when a Fleetsync or MDC ANI ID is decoded. This does not include serial decoding.

•When connected to a serially controlled radio, iDEN, Sepura, Kenwood or Johnson displays.
•INTCOM displays when the front panel IC button is pressed.
•EnetIC displays when the console generated intercom is received.
•CTX F# displays when the console mode IP-223 decodes tones from a tone console in Console mode.
•CRX F# displays when the IP-223 transmits wire-line audio to a legacy tone console in Console mode.
•PTX F# displays when the IP-223 decodes tones from a legacy tone console attached in parallel in Tone mode.
•CPT F# displays when the IP-223 transmits to a line if the line-to-line crosspatch is enabled.
•Ring displays when there is an incoming phone call in Phone mode.
•Offhook displays when the line is in use during a phone call.
•LLM displays when no phone line is connected to the PIB or TDI in Phone mode.
•NO LINE ENABLED displays after power-up if neither line is enabled.
•Scan List.... displays during power up while the IP-223 is communicating with serial controlled radios that
support the Scan List feature.
To toggle the LCD display, do the following:
1. Press and hold the line button and then momentarily press the IC button.
Three different displays are available with each press of the IC button:
•While pressing the line button, press the IC button once.
The IP Address and Mask Address of the unit displays.
•Continue to hold the line button, then press the IC button a second time.
The TX alignment tones are turned ON.
•Continue to hold the line button, then press the IC button a third time.
The RX VU meter displays.
2. Press the IC button a fourth time to clear the display and return to the normal LCD display.
3. Release the line button.
Line Button
The Line button is used to select which radio, or line, the handset audio is routed and which line is being monitored. The
handset line selection is displayed as an asterisk (*) in the right most column of the LCD display. An asterisk (*) on the top
line of the display indicates a connection to line 1, and an asterisk (*) on the bottom line of the display indicates a connection
to line 2.
TX LED
The TX LED provides a visual indication the IP-223 is generating IP packets. When the LED is illuminated, packets are being
transmitted to the network.
LNK LED
The LNK LED provides a visual indication of the Ethernet connection. When the LED is illuminated, a valid network
connection is established.

10/100 Ethernet Connector
The 10/100 Ethernet connector provides the LAN or WAN connection for the IP-223.
Serial Connector
The serial connector (DB9) is used for either of the following:
•To program an initial IP Address into the IP-223 unit, if the IP Address cannot be programmed through the
Ethernet port on the installed system.
NOTE: To communicate with HyperTerminal, the jumper setting must be RS-232.
•To provide serial communication to various radios. Both radio (or line) 1 and radio (or line) 2 are supported on
this connector, with the appropriate splitter cable.
NOTE: You must adjust the position of the jumper, on J35 when using line 1, or on J26 when using line 2, according to
the serial connection type for the radio interface shown below. See “Jumper Positions” on page 25 for more
information.

Radio 1 and Radio 2 (Line 1 and Line 2) Connectors
Two (2) DB25 connectors are provided for connection to various audio devices. The pinouts shown in Table 4 are used when
custom cables need to be fabricated.
Power Connection
The IP-223 requires +12 to +16VDC, ~700mA of clean power. A 3-pin screw terminal receptacle is provided on the right rear
of the unit, pin 1 is the positive terminal, pin 2 is the ground terminal, and pin 3 is the earth ground terminal.
As with all communication equipment earth ground should be used. Earth ground is a low impedance path to earth for the
purpose of discharging lightening, static, and radiated energy.
