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.
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 toneequipped 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
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.

NOTE: Radio 1 and radio 2 are also referred to as line 1 and line 2 in this manual.
FIGURE 79. IP-223 Case Top Test Points
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.
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.
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.

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.
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, TDI, C-6200, or the NI-223 for a telephone connection, 100kBit is required since it is a constant, fullduplex conversation.
In general, Telex systems require multicast to function. The network must be able to support the multicast traffic generated by the system.
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 radios, such a system can appear to work flawlessly for a period of time, then no longer work.
23
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
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.
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%.
24
CHAPTER 3
Installation and Level Settings
NOTE: Connections to radios differ from connections for remote operation; therefore connections are discussed separately.
An example of the jumper positions are shown in Figure 82. 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 placed on the center pin indicating the jumper is in the NULL position.
FIGURE 82. 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.
25
Installation and Level Settings
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 83.

FIGURE 83. 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.
26
Local/Radio Connections
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.
NOTE: Shielded cable is recommended.

To connect the radio receiver audio to the IP-223, 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 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.

The COR I/O connection indicates that audio is being received from the radio. The COR connection is provided at DIG6, pin 20 of the DB25 connector.
Connect the radio PTT circuit to the PTT relay contact terminals 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.
Connect the radio MON circuit to the MON relay contact terminals 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.
The IP-223 provides two (2) 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 33. 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.

In addition to the two standard relay closures, seven (7) 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 down to ground and can be jumper selected to pull up to either +5V or the power supply voltage (minimum +12V).
Jumpers J8 (line 1) and J30 (line 2) are used to select the pull up voltage. Jumper position A pulls up to +5V and jumper position B pulls to the power supply value.
NOTE: 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 33.
The IP-223 connection can be used for a recorder output or as a CTCSS output:
Recorder output - The analog audio is generated at the connection.
CTCSS output - Each function tone can be assigned a CTCSS number which corresponds to a CTCSS frequency. See “CTCSS Tone Frequency Table” on page 131.
Tone/Console Operation
Tone and Console operation require jumpers set to specific locations. The following section discusses the jumper settings. See “Jumper Locations” on page 125.

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 (1) 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.
PCB 750743 or PCB 750630 revision C and higher
Two (2) 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.
NOTE: PCB 750630 revision A does not have these jumpers.

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.
Cross mute information to local consoles is provided at DIG0, pin 8 of the DB25 connector.
Supervisory information to and from consoles is provided at DIG1, pin 21 of the DB25 connector. The supervisory I/O is both an input and an output.
Supervisory input and output in console, tone or local mode behaves as follows:
Console Mode – Input - An Ethernet packet supervisor is sent on detection.
Output - When an Ethernet packet is received. The line level is set.
While under supervisory control, TX traffic from the Ethernet to the console is muted. The console’s audio to the Ethernet is muted. Handset PTT and the IC button are disabled.
Tone Mode – Input - An Ethernet packet supervisor is sent on detection.
Output - When an Ethernet packet is received, the line level is set.
When an Ethernet packet is received, the line level is set.
Local Mode - InputNo affect on I/O.
Output - No affect, when Ethernet packet is received.
While under control, manual PTT and the IC button are disabled.
NOTE: Information on programming the supervisory I/O is provided in the “Setup Information” chapter of this manual starting on page 33..
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.

Level Adjustments
The IP-223 has a TX alignment tone and an RX alignment VU meter accessible 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.
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 signal 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.
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 (Automatic Gain Control) 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 always displays 0dBm, the targeted level for the AGC circuitry.
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.
31
Installation and Level Settings
To adjust the TX monitor, do the following:
1.In the options section of the Per Line Setup window, select the TX Monitor.
NOTE: 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.
2.Verify the RX alignment is completed first.
To perform a standard alignment for a 4-wire system, do the following:
1.Transmit a 0dBm test tone on the TX audio pairs pins 13 and 25.
2.Measure the RX level on test point TP13 for line 1 or TP1 for line 2.
3.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.
4.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 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 open to receive audio so CTCSS is present. Adjust the Radio 1 CTCSS potentiometer (R50) or Radio 2 CTCSS potentiometer (R53) until the desired level is achieved.
The IP-223 is factory tuned to the frequencies shown below. The detection frequencies cannot be changed as they are coded into the software. However, any actual function or output can be made to work with any existing programmed frequency. Please consult the factory for special requirements for frequency selections.
