CHAPTER 1
Overview
The IP-223 Remote Adapter Panel (IP-223) provides a reliable means of remotely controlling two 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 WA N (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 for local control.
FIGURE 1. Local and Tone Mode Connections
5
Overview
• Ethernet TX and LINK LEDs
• PTT, Monitor, F1 and F2 relays (programmable to any
function tone or revert to F1)
• Four (4) PTT modes and three (3) monitor modes
• Nine selectable PTT frequencies
• 7 digital outputs for channel selection, completely
programmable per function tone
• CTCSS (Continuous Tone Coded Squelch System)
generation (64 frequencies)
• Hardware and software gain control
• Local handset port for monitoring activity and
transmission back to base or to radio
• RS-232C port on rear for initial configuration and
direct radio control
• Single function tone recognition (16 function tones)
• RX (Receive) audio squelch
• Crosspatch capability
• ANI (Automatic Number Identification) over the air –
decode and display
• Provides iDen interface
• Supports Sepura SRM2000, TETRA radio
• E.F. Johnson RS5300 P25 radio interface
• Remote Crosspatch capabilities
• POTS line fail-over
• Phone line interface
• MDC and Fleetsync Decode
• 5/6 Tone signalling encode/decode
• Kenwood radios interface
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 regenerates the industry standard tones for control of existing tone remote
adapters.
FIGURE 2. Console Mode Connection
Phone Mode – Using the PIB-223 Phone Interface Box, 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.

IP-223 Specifications
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.

CHAPTER 2
Communications System Design
Designing an IP-223 system requires an understanding of the radio network and how the various radios and communication
equipment are connected.
The first step in designing an IP-223 system is to create a roadmap of the radio, console, and any other communication
equipment locations. This roadmap must include the following:
• Multicast addresses for each channel of TX (transmit) and RX (receive) communication.
• Port numbers for each channel of TX and RX communication.
• Base IP addresses assigned to each console and IP-223 on the network.
Network Requirements
Bandwidth
Each VoIP channel requires 50kBit of bandwidth while active. Full-duplex conversation (audio in each direction) requires
100kBit of bandwidth.
NOTE: Most radio voice communications are half-duplex (only in one direction at any one time), thus requiring 50kbits.
Some radio systems transmit “go-ahead” beeps when it is clear to talk. In order for the console operator to hear the beeps, the
system must support full-duplex communication. Full-duplex bandwidth may only be required for the first few seconds of a
conversation, due to the brief nature of the “go-ahead” beeps at the beginning of the transmission.
When using a PIB-223, C-6200, or the NI-223 for a telephone connection, 100kBit is required since it is a constant, full-duplex
conversation.
Multicast
In general, Telex systems require multicast to function. The network must be able to create a static multicast address that is
accessible at all times.
It is very common for networks to enable multicast after an IGMP (Internet Group Management Protocol) join message is sent
out, and then “prune” off branches after a period of time. Due to the intermittent usage patterns of two-way radio, such a
system can appear to work flawlessly for a period of time, then no longer work.
13
Communications System Design
NOTE: When using Cisco technology, IP PIM dense mode is generally recommended. Generally speaking, sparse-
dense-mode can also be implemented effectively. We recommend explicitly joining the multicast group with an
IP IGMP static-join X.X.X.X command. For more information on Cisco and IGMP, visit www.cisco.com
Internet Group Management Protocol (IGMP)
IGMP can be used to control where multicast is allowed to propagate. When a console on the subnet is expected to be
continually operational, multicast must be active for that subnet at all times.
Network Performance
Networks should perform well under any loading conditions. The default audio delay is 120ms, plus any delay added by the
network. While delay alone does not cause issues, variable delay (jitter) does. Jitter in a network cannot exceed the
maximum packet buffer of any individual product buffer. Refer to the individual product manuals for these specifications. For
example, the IP-223 can handle approximately 600ms of network jitter.
NOTE: Losing more than 5% of the total packets transmitted compromises audio quality and system performance.
Optimally, packet loss should be less than 1%.

Installation and Level Settings
Local/Radio Connections
NOTE: Connections to radios differ from connections for remote operation; therefore connections are discussed
separately.
Jumper Positions
An example of the jumper positions are shown in Figure 7. In the figure, jumper 14 (J14) is shown in position A, jumper 3
(J3) is shown in position B, and jumper 23 (J23) has been hung on the center pin indicating the jumper is in the NULL
position.
FIGURE 7. Jumper Positions
To adjust the position of a jumper, do the following:
1. Remove power from the IP-223 unit.
CAUTION: Failure to remove power may cause damage to the IP-223.
2. Remove the six (6) screws from the case top.

3. Carefully slide the case top forward past the IC and LINE buttons, and then lift up to gain access to the PCB (Printed
Circuit Board) as shown in Figure 8.
FIGURE 8. IP-223 PCB Assembly
4. Locate the desired jumper on the PCB assembly and use needle nose pliers to adjust the jumper, if necessary.
5. Carefully lift up the case top and place it into position on the chassis bottom.
6. Secure the case top into position using the six (6) screws.
7. Connect power to the IP-223 unit.
16
Local/Radio Connections
TX Audio Connection
The IP-223 has a number of options when connecting to the radio. Different jumper settings are required for different
revisions of the PCB installed in the IP-223 unit, and are noted below. Set the jumper position listed for the line according to
the connection type shown below.
If the radio transmit audio output is balanced, connect to pins 13 and 25 of the DB25 connector. If the transmit audio is single
ended, use pin 25 of the DB25 connector.
Shielded cable is recommended.

RX Audio Connection
To connect the radio receiver audio to the IP-223, several settings are required. Different jumper settings are required for
different revisions of the PCB installed in the IP-223 unit, and are noted below. Set the jumper position on the jumpers listed
for the line according to the connection type shown below.
If the radio receiver audio output is balanced, connect to pins 12 and 24 of the DB25 connector. If the receiver audio is single
ended, use pin 24 of the DB25 connector. The audio source must be after the squelch circuit to prevent sending continuous
noise to the remote console. If a high-impedance point in the receiver is used, a shielded cable is recommended.

COR (Carrier Operated Relay) I/O (Input/Output)
The ability to control RX packets to the Ethernet is provided at DIG6, pin 20 of the DB25 connector. This overrides LAM
(Line Activity Monitor) control and uses COR from the radio to generate RX packets to the consoles.
PTT Connection
Connect the radio PTT circuit to the PTT relay contact terminals of the panel on the DB25 connector. Usually the common of
the relay contact switch is grounded and the normally open contact connects to the PTT input. An alternative method to ground
the common of the relay internal to the unit is to jumper R377 (line 1) and R381 (line 2) with a piece of wire soldered closed.
Monitor Connection
Connect the radio MON circuit to the MON relay contact terminals of the panel on the DB25 connector. Usually the common
of each relay contact switch is grounded and the normally open contact connects to the MON input. An alternative method to
ground the common of the relay internal to the unit is to jumper R376 (line 1) and R380 (line 2) with a piece of wire soldered
closed.
R1 and R2 Relays
The IP-223 provides two relay closures for controlling the frequency of the radio, or switching a remote ancillary device. The
F1 and F2 contacts can be connected through the DB25 connector. Usually the common of each relay contact switch is
grounded and the normally open contact connects to the radio frequency control terminals. Information on programming the
R1 and R2 relays is provided in the “Setup Information” chapter of this manual starting on page 23. An alternative method to
ground the common of the relay R1 internal to the unit is to jumper R375 (line 1) and R379 (line 2), and for relay R2 jumper
R374 (line 1) and R378 (line 2) with a piece of wire soldered closed.
18
Tone/Console Operation
Digital I/O
In addition to the two standard relay closures, seven lines of digital I/O are also included. These lines are open-collector
transistor outputs. They can be programmed on a per line basis to generate any of 128 combinations. They pull to ground and
can be jumper selected to pull up to either +5V or the power supply voltage (minimum +12V). Jumper J8 (line 1) and J30 (line
2) are used to select the pull up voltage. Jumper position A pulls up to +5V and the B jumper position B pulls to the power
supply value. Some radios provide a pull-up voltage. When this occurs, place the jumper into the “null” position. Information
on programming the digital I/O lines is provided in the “Setup Information” chapter of this manual starting on page 23.
CTCSS (Continuous Tone Coded Squelch System) Connection
The IP-223 is programmed with a full range of CTCSS frequencies. Each function tone can be assigned its own CTCSS
frequency for PTT operation, or a number of CTCSS tones can be set using different function tones. This connection is also a
programmable recorder output pin. A single ended, cap coupled, low impedance output is available on pin 11 of the DB25
connector.

2-/4-Wire Jumper Settings
2-Wire / 4-Wire Selection: Line 1 Line 2
2-Wire A position J33 and J34 J5 and J6
4-Wire B position J33 and J34 J5 and J6
The RX termination J14 (line 1) and J24 (line 2) should be placed in jumper position A on 4-wire systems for a single unit at
the end of a line. If multiple units are connected in parallel, only one unit should have the RX termination jumper in the A
position. The RX termination jumper should be in the NULL position on the rest of the units.
For 2-wire operation:
• PCB 750743 or PCB 750630 revision C and higher - Set J14 or J24 to the NULL position.
TX Side Settings
PCB 750743 or PCB 750630 revision C and higher
Two jumpers on the transmit pair allow a degree of control over the output impedance. The jumper positions for each line,
depending on how many consoles are placed in parallel, are shown below.

Local PTT I/O
The Local PTT I/O is used to generate TX Ethernet traffic on a local keyed system as opposed to the 2175Hz detection on a
tone keyed system. The input is at DIG5; pin 23 of the DB25 connector. The TX condition is caused by an active low.
19
Installation and Level Settings
Cross Mute I/O
Cross mute information to local consoles from the Ethernet is provided at DIG0, pin 8 of the DB25 connector.
Supervisory I/O
Supervisory information to and from consoles through the Ethernet is provided at DIG1, pin 21 of the DB25 connector. When
the IP-223 port is in either the console or tone mode with Supervisory enabled, Supervisory ON and OFF packet bursts are
sent to the Ethernet with the sense of logic levels at pin 21 of the IP-223 port. Information on programming the supervisory I/
O is provided in the “Setup Information” chapter of this manual starting on page 23.
The IP-223 provides the following when the ON/OFF burst packets are received from the Ethernet:
Console Mode – Mutes TX traffic from Ethernet to console.
Tone Mode – Pulls the Supervisory line low for control of parallel console control.
Local Mode - No control of the supervisory pin.
Level Adjustments
Once the IP-223 unit is connected to the system, the level potentiometers can be set. Access to test and adjustment points on
newer versions of the IP-223 are provided through labeled openings on the case top and on the front panel of the unit. On older
versions of the IP-223 access to some of the test and adjustment points is provided through labeled openings on the front
panel, however, the case top needs to be opened to access the other test and adjustment points.
General Alignment
The IP-223 has a TX alignment tone and an RX alignment VU meter accessed from the front panel of the unit.
• Press and hold the line button and then momentarily press the IC button twice to generate the 1kHz 0dB TX
alignment tone on both lines.
• Press and hold the line button and then momentarily press the IC button three times to display the RX VU
meters.
Radio/Line TX Level
The Radio 1 TX test points (TP2 and TP6) and the Radio 2 TX test points (TP8 and TP9) are located on the front panel of the
IP-223. These provide a point to measure the actual value being placed into the radio or balanced TX line. The front panel
accessible adjustment Radio 1 TX potentiometer (R47) and Radio 2 RX potentiometer (R61) are used to adjust these levels.
NOTE: If the unit is placed into single-ended mode, the radio TX+ should be measured with respect to ground.
It is also possible to place jumper J9 (line 1) or J26 (line 2) into the “A” position to decrease the output of the TX line by a
factor of 10. The final adjustment should allow for undistorted audio to be transmitted for the full range of transmission levels
at the desired deviation. This can be accomplished by turning on the TX alignment tone and adjusting the TX output to 0dB, as
measured into a 600 ohm load.
20
Level Adjustments
Radio/Line RX Level
Standard Alignment Procedure for a 2- or 4- wire System:
• Inject a 0dBm test tone on the RX pair (4-wire pins 12 and 24: 2-wire pins 13 and 25).
• Measure the RX level on test point TP13 for line 1 or TP1 for line 2.
• Adjust potentiometer R175 for line 1 or potentiometer R110 for line 2 until 0dBm is measured between the test
point and GND. (0dBM = 2VPP = .707VRMS)
• Detune slightly 1-2dBm to provide overhead for large transients.
• AGC compression potentiometers RV5 for line 1 and RV1 for line 2 control the aggressiveness of the AGC
circuitry, if enabled. The AGC can be used to enhance the gain capabilities of the RX circuitry. Set RV5/RV1
fully clockwise and, if required, back off 10 to15 degrees maximum.
• Use the RX alignment tool (VU meter) accessed through the LCD display (press and hold the line button and
then momentarily press the IC button 3 times) to verify the dBm level. The reading should be 0dBm with the
AGC turned off. If the AGC is ON, it is likely the RX alignment software will always display 0dBm, the targeted
level for the AGC circuitry.
Line TX Monitor Level (Tone and Console Mode only)
PCB 750743 or PCB 750630 revision C and higher
The Line TX Monitor Level adjustment is used when the IP-223 is connected to consoles set in 4-wire mode. This allows for
local TX audio to be sent back on the Ethernet and played at other consoles so both sides of the radio traffic can be heard. The
alignment for TX monitor is similar to 4-wire RX alignment.
NOTE:
1. The TX Monitor field must be selected in the Options section on the Per Line Setup window.
2. If this feature is not necessary, or the line is in 2-wire mode, the TX Monitor field in the Options section on the Per
Line Setup window should be cleared.
3. Make sure the RX alignment is completed first.
Standard Alignment Procedure for a 4-wire System:
• Inject a 0dBm test tone on the TX audio pairs pins 13 and 25.
• Measure the RX level on test point TP13 for line 1 or TP1 for line 2.
• Adjust potentiometer R390 for line 1 or potentiometer R391 for line 2 until 0dBm is measured between the test
point and GND. (0dBM = 2VPP = .707VRMS)
NOTE: Do not adjust the RX potentiometers.
• Use the RX alignment tool (VU meter) accessed through the LCD display (press and hold the line button and
then momentarily press the IC button 3 times) to verify the dBm level.
CTCSS Level
The CTCSS level is measured by connecting an oscilloscope or RMS meter to ground and Radio 1 CTCSS test point (TP7) or
Radio 2 CTCSS test point (TP10). With the radio connected to the CTCSS output, have the remote console key up so CTCSS
is present. Adjust the Radio 1 CTCSS potentiometer (R50) or Radio 2 CTCSS potentiometer (R53) until the desired level is
achieved.

CHAPTER 4
Setup Information
The setup information for the IP-223 is accessed by using a web browser, such as Internet Explorer™. This section describes
the programming information for the IP-223. It includes information on setting the IP address, accessing the IP-223 web setup
windows, the setup window standards, and an explanation of the fields on each window used to program the IP-223.
Setting the IP Address Information
Before entering the setup information for the IP-223, the IP address and Network Mask must be assigned to the IP-223 by
the use of a web browser or Windows™ HyperTerminal™ if the assigned IP address is not accessible on your network.Contact
your network administrator to obtain the network IP address and Mask.
For the IP-223 to interface successfully with the LAN or WAN, the IP addresses of the IP-223 and your PC must be on the
same subnet. IP addresses consist of four numbers separated by periods. For example, 10.2.99.101. For more information on
IP Addresses and subnets, consult your network administrator.
In order for the PC and the IP-223 unit to communicate via IP, both devices need to be in the same subnet.
NOTE: For operation on different subnets, a gateway address must be configured.
These IP addresses reside in the same subnet:
PC IP Address: 10.2.99.250
IP-223 IP Address: 10.2.99.251
IP-223 Network Mask: 255.255.255.0
To display the IP address and Network Mask assigned to the IP-223, do the following:
1. Connect power to the IP-223.
2. The IP address and subnet mask are displayed on the LCD momentarily upon power up. To check the IP address and
subnet mask at any other time, press and hold the line button on the front panel of the IP-223, and then momentarily
press the IC button.
The IP address is displayed on the top line of the LCD, and the Network Mask is displayed on the bottom line of the
LCD.
23
Setup Information
Verify the IP address and Network Mask obtained from your network administrator to the IP-223 addresses. If any portion of
the first three segments of the IP addresses for the PC and the IP-223 do not match, the IP-223 addresses must be changed to
match the PC subnet.
If the IP address and Mask need to be set up using the serial port, see “Using HyperTerminal” below.
