Safe Handling of CMOS Integrated Circuit Devices
Many of the integrated circuit devices used in communications equipment are of the Complementary
Metal Oxide Semiconductor (CMOS) type. Because of their high open circuit impedance, CMOS
integrated circuits are vulnerable to damage from static charges. Care must be taken handling, shipping,
and servicing them and the assemblies in which they are used.
Even though protection devices are provided in CMOS integrated circuit inputs, the protection is
effective only against over-voltage in the hundreds of volts range such as is encountered in an operating
system. In a system, circuit elements distribute static charges and load the CMOS circuits, decreasing the
chance of damage. However, CMOS circuits can be damaged by improper handling of the modules, even
in a system.
To avoid damage to circuits, observe the following handling, shipping, and servicing precautions:
1. Prior to and while servicing a circuit module, particularly after moving within the service area,
momentarily touch both hands to a bare metal, earth-grounded surface. This will discharge any static
charge that may have accumulated on the person doing the servicing.
N
OTE: Wearing a conductive wrist strap will minimize static build-up during servicing.
2. Whenever possible, avoid touching any electrically conductive parts of the circuit module with your
hands.
3. Power down the unit before installing or removing the circuit module.
4. When servicing a circuit module, avoid carpeted areas, dry environments, and certain types of
clothing (silk, nylon, etc.) because they contribute to static build-up. Similarly, disconnect the test
probe prior to removing the ground lead.
5. All electrically powered test equipment should be grounded. Apply the ground lead from the test
equipment to the circuit module before connecting the test probe.
6. If a circuit module is removed from the system, it is desirable to lay it on a conductive surface (such
as a sheet of aluminum foil) that is connected to ground through 100k of resistance.
7. When soldering, be sure the soldering iron is grounded and has a grounded tip.
8. Prior to connecting jumpers, replacing circuit components, or touching CMOS pins (if this becomes
necessary in the replacement of an integrated circuit device), be sure to discharge any static build-up
as described in procedure 1. Since voltage differences can exist across the human body, it is
recommended that only one hand be used if it is necessary to touch pins on the CMOS device and
associated board wiring.
9. When replacing a CMOS integrated circuit device, leave the device in its conductive rail container or
conductive foam until it is to be inserted into the printed circuit module.
10. All low impedance test equipment (such as pulse generators, etc.) should be connected to CMOS
device inputs after power is applied to the CMOS circuitry. Similarly, such low impedance
equipment should be disconnected before power is turned off.
11. Replacement modules shipped separately from the factory will be packaged in a conductive material.
Any modules being transported from one area to another should be wrapped in a similar material
(aluminum foil may be used). Never use non-conductive material for packaging these modules.

Introduction to the IPE2500A Paging Encoder/Desktop Controller
The IPE2500A Paging Encoder/Desktop Controller provides a cost-effective console-like alternative to
conventional radio control. This standard unit is a “tone” control remote. However, by adding the
optional field installation kits to the IPE2500A and using the CARD Suite Programming Software, it can
be configured for DC, Local, and E&M and tone, allowing further possibilities for remote dispatch.
When used with a compatible remote adapter such as the ITA2000A, the IPE2500A provides dispatch
control. Nearly every aspect of the operation can be programmed using the CARD Suite Programming
Software for specific control needs. The multiple frequency control, two-line LCD display, aliasing
functions, intercom, parallel status updating, programmable voice delay, paging encoder, H.E.A.R., and
multiple desk set support are standard features that provide powerful fixed station control.
Each of the four programmable buttons can be configured to perform two functions. In addition, the four
optional inputs and outputs for the IPE2500A that can be programmed for various uses. With optional
relays, outputs can be configured for On-Air Light, General Purpose Control, “On-Off,” PTT, Vox
Detect, Data Enable, and Guard Tone Detect. Inputs can be configured for Button Remap, E Lead for
E&M, Output Link, and Link to a Page.
The IPE2500A also includes DTMF, 2-Tone, Plectron, and 1500, 2805, and custom 2-Tone paging
formats. Buttons can be configured for preset paging. With the relay control option, the IPE2500A is
capable of local, E&M, and E&M with tone control.
Multi-line Select is available with the IPE2500A. When equipped, the unit is referred to as an
IPE2500A-MLS. This unit provides single or multi-select transmission capability, tone remote control of
two to four base stations, vox detect indication for each line, manual unselect audio mute, mute unselect
audio on transmit, and is two-wire or four-wire compatible.

A 2175 Hz Low Level Guard Tone (LLGT) is generated for the duration of the transmission. The
LLGT is not generated during monitor. Because voice is present with this LLGT, a 2175 Hz filtering
is required in the tone panel.
When the monitor (CTCSS disable) is activated, the HLGT is generated for 120 ms, then a function
tone of 2050 Hz is generated for 40 ms.
Tone Levels
Assuming that the ITA2000A Tone Remote Adapter has the HLGT output level set to 0 dBm:
The FT level and audio voice level are –10 dBm (10 dB below HLGT)
The LLGT level is –30 dBm.
The HLGT and FT durations are programmable.
Some tone panels use the value of the FT frequency to provide certain radio control functions. If the
radio supports channel changes from an external logic source, the FT1 frequency of 1950 Hz could be
used to change the radio to channel 1. An FT6 frequency of 1450 Hz could change the radio to
channel 6. This operation is identified as “channel steering.”
DTMF Decode/H.E.A.R. System Support
The IPE2500A will decode incoming DTMF and display the ID numerically or as a preprogrammed
alias. The DTMF decode function will provide H.E.A.R. system support using a base ID DTMF code to
perform speaker un-muting and alert functions.

Operation
The IPE2500A provides radio system control from a remote location. It sends tone control to the remote
adapter through a telephone line to control radio functions such as transmit, channel steering, and
monitor.
Receive audio from the radio system is sent to the desk sets via the same line connection in two-wire
applications, or by using another pair in four-wire applications.
The numeric keypad buttons are used for selection of different base station frequencies. These
frequencies are dependent upon your radio’s capabilities. Changes to system parameters require the use
of the CARD Suite Programming Software and the programming cable, which are sold separately.
Complete information is contained in the “CARD Suite Programming Software” section of this manual.
Display
The IPE2500A has a backlit 216-character super-twist LCD display to provide valuable operator
information. This information allows the operator to determine the status of the unit. The following
describes the display at various states:

Operation IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller
Receiving Calls
When power is applied, the IPE2500A is in the receive mode, allowing receive audio to be heard through
the speaker or handset. It is always in receive mode unless the unit is transmitting, or a parallel desk set
is transmitting (parallel mute function enabled).
The IPE2500A Desk Set contains an internal or local speaker and a handset speaker that operate as
follows:
When the handset is in the cradle, or on-hook, receive audio is heard on the internal speaker. In some
operational modes, this can be changed, i.e., muting the speaker during TX of a parallel desk set.
When the handset is off-hook, receive audio is routed to the handset. By using the front panel
buttons, you may optionally select to hear audio through the local speaker in addition to the handset.
Initiating Calls
Before initiating a call, press the MONITOR button to verify that the radio channel is clear. The
MONITOR button remains illuminated until a transmit function is initiated. This operation is typically
required when a community or shared repeater is in use. Always allow time for the radio channel to be
established. In addition, if the unit is configured to generate PTT IDs and to generate side tone, a tone
will be heard during the PTT pretime and PTT generation. A voice delay can be programmed via the
CARD Suite software to eliminate this waiting time if no PTT ID is used.
To initiate a call, press the
PTT button. When the desk set is transmitting, the
TRANSMIT button, the handset push-to-talk (PTT) pressbar, or an accessory
TRANSMIT LED illuminates. The TRANSMIT button
or handset PTT bar must be held down while talking to the radio user and released to listen. When the
transmission is completed, the
TRANSMIT LED extinguishes and the desk set returns to the receive
mode.

IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation
Handset Transmit
Use of the handset is recommended when the desk set is located in noisy surroundings or if full-duplex
two-wire operation is desired. This may be used for types of systems that provide talk courtesy tones,
such as trunking. Press the handset PTT bar or
TRANSMIT button and speak into the handset
microphone to transmit when the handset is off-hook.
Transmit From Internal (Local) Microphone
Use the internal microphone only in low noise environments. The handset must be on-hook for the local
microphone to operate. Press the
TRANSMIT button and speak in the direction of the integral
microphone. For the best transmit audio quality, maintain a distance of about 18 inches from the
microphone.
Transmit From Desk Microphone or Footswitch
All models can be keyed to transmit with an external desk microphone through the audio accessory port.
When a PTT signal is asserted through this port, TX audio will also originate through this port. Use of
the GAI-Tronics XDM002A or XDM004A Desk Mic, or compatible microphone, is recommended.
N
OTES:
1. The polarity of the desk mic PTT and monitor inputs is CARD Suite programmable. If the polarity
of either of these inputs is set for normally closed, it is necessary to keep the desk microphone
connected at all times. Removing the microphone during operation may cause the keyboard to stop
responding. This is caused by the internal pull-ups on these two pins. If the desk mic maintains a
normally closed connection to ground, the connection is opened when the button is pressed and the
desk set recognizes the key as pressed. Without the desk mic connected, the connection remains
open and the desk set continually sees the key pressed.
2. The IPE2500A has three microphone sensitivity adjustments. Refer to the “Installation” section of
this manual.

Operation IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller
Parallel Status Operation
The IPE2500A supports parallel status updating. This feature allows all dispatch positions to know the
status of the base station.
To decode this information, the unit senses high level guard tone (HLGT), then decodes the function tone
that follows. Due to various tone control schemes supported by the unit, it is important to understand the
rules of decoding the function tones.
1. If the monitor function is decoded, the unit is placed into the monitor mode. If any transmit function
tone is programmed to be the same as the monitor function tone, that transmit tone will not be
decoded.
2. If two transmit function tones are programmed to the same frequency, only the first of the tones in
the sequence will be decoded; the subsequent transmit function tones set to the same frequency will
not be decoded.
3. If a PTT function tone is programmed, it is not decoded since this does not contain channel control
information. If a transmit function tone is programmed to be the same as the PTT function tone, the
transmit function tone will not be decoded.
4. If a transmit function tone is programmed to be the same as a tone supervisor tone, the supervisor
function will be decoded.
To illustrate, the priorities of the decode function are as follows:
Highest priority: Monitor Function Tone
Supervisor On Function Tone
Supervisor Off Function Tone
PTT Function Tone
Lowest priority: Transmit Function Tone (F1 to F15, F16 with Monitor disabled)
OTE: Parallel status update operation is not available with the IPE2500-MLS.
N
Frequency Display
When shipped from the factory, the LCD display shows FREQ: XX, with XX being 1 to 16, depending on
the selected frequency.
Each time the IPE2500A is powered up, the status of the base/radio is unknown. The desk set LCD
display flashes the last selected frequency when the unit was powered down. The display continues
flashing until a transmission or frequency change is entered, or a parallel unit initiates a transmission or
frequency change. Each time a guard tone is detected on the line, the desk set assumes the status of the
base/radio is unknown until a function tone is decoded at the proper time.
Note that the display remains flashing even when a monitor command is initiated after power-up. This is
because the monitor command does not control which frequency is being monitored and the state of the
base/radio is still unknown.
Since the IPE2500A-MLS does not support parallel status updating, the displayed frequency or alias is
never flashed. The operator must ensure that the base station is on the proper frequency.

IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation
Numeric Keypad Frequency Selection
The IPE2500A can be configured for multiple frequency control with the CARD Suite Programming
Software. When the desired frequency is selected using the numeric keypad, that frequency change
command is sent to the base. Other parallel units will reflect the newly selected frequency. Note that if
Direct DTMF is enabled, the numeric keypad is used for direct DTMF dialing. To select a frequency on
an IPE2500A only, the operator must first press the

monitor burst to monitor the newly selected frequency.
Press and hold
TRANSMIT or the handset PTT bar to select the new frequency, exit the frequency
selection mode and begin transmitting on the newly selected frequency.
PTT Function Tone (Key-up Only Function Tone)
This feature, compatible with tone and optional E&M with tone control, allows the desk sets to use only
a single function tone burst generation when a voice transmission is required. The parallel status
updating function is also modified. This is useful when the base station is only capable of one frequency
control or when wildcard frequency keying is required.
When a frequency change command is sent, the desk sets generate normal HLGT and frequency
function tones.
When the monitor function is sent, the normal monitor command is sent.
When a voice transmission is required, the HLGT and programmed PTT function tone is sent as the
transmit command. No channel frequency function tones are used during a voice transmission.
When a parallel unit transmission is detected, the parallel status updates the selected function tone
only if the frequency falls within programmed function tone frequencies. When a parallel PTT
function tone is detected, the function tone of the unit is not updated and continues to be unknown
(flashes) until a frequency change command is detected.
17 03/12
Operation IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller
Tone Supervisor Control
The IPE2500A offers a tone supervisor control feature which locks out transmission of parallel units
upon detection of the proper tone control sequence. This feature cannot be activated during a parallel
transmission. The supervisor unit is programmed with appropriate on/off frequencies and a supervisor
button. Parallel, non-supervisor units are programmed with the same on/off frequencies.
When the supervisor unit operator presses the supervisor button and turns on the supervisor function,
programmed parallel units will not allow any transmission and their keyboards will be locked. The
display flashes
SPV until the supervisor turns the function off.
The IPE2500A can optionally be configured for relay controlled supervisor using a relay programmable
button.
“Hard” Supervisor Control
To ensure parallel units are locked out of transmission upon demand by the supervision position, the
relay I/O module should be used and the supervisor unit placed closest to the transmitter or adapter. Note
that tone supervisor cannot be activated during a parallel transmission.
Secure Operation
When using Tone or E&M with Tone control, it is possible to use two-function tone generation to adapt
to certain secure capable systems. Parallel status does not support this mode of operation.
In this configuration, the IPE2500A generates a HLGT, a coded/clear function tone, then the channel
control function tone. Each of the coded and clear function tones are programmable to the same
frequencies as the channel control function tones and is the same level.
NOTE: A programmable button should be used to toggle the state of the unit from coded to clear
transmission mode.
By adding factory or field-installed options, other types of control, besides tone, may be used.
03/12 18
IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation
DTMF Decode
The DTMF decoder is primarily used for automatic number identification, or ANI, by the dispatch
operator. ANI is used to communicate to a dispatcher the identity of the transmitting radio. This use of
DTMF is transmitted only in one direction without the receiving unit acknowledging the receipt of
information.
When the field unit presses the PTT button of the radio, the radio generates a preprogrammed sequence
of DTMF digits prior to opening the voice path of the radio. The IPE2500A decodes these digits and
displays the ID either numerically or with a preprogrammed alias. The dispatcher then knows, without
the field radio user having to speak his identity, which radio is being received.
H.E.A.R. System Operation
The H.E.A.R. (Hospital Emergency Administration Radio) system operation is typically used in hospital
emergency rooms. During H.E.A.R. operation, the internal speaker of the IPE2500A would typically be
muted so that normal radio traffic is not heard in the emergency room. A DTMF sequence is transmitted,
prior to voice transmission, by ambulance or public safety personnel to access the emergency room’s
radio system.
To perform H.E.A.R. functions, the desk set contains a base ID used to deactivate the speaker mute.
When the desk set decodes a valid DTMF sequence, it compares the sequence to the H.E.A.R. base ID.
If the ID matches, the desk set unmutes the speaker, allowing received audio to be heard by emergency
room personnel. The unit must be returned to mute mode manually.
The speaker mute is achieved by programming a mute button using the programmable buttons found on
the front panel of the IPE2500A. An optionally installed H.E.A.R. system relay and/or audible 2 kHz
alert tone of programmable duration can also be programmed for activation upon receipt of the proper
base ID. Refer to the CARD Suite Help file for detailed programming instructions.

Optional DC Control Kit
NOTE: This optional feature requires the XDC0001A DC Control Kit and XAC0100A Mounting
Kit.
DC currents from +14 to –14 mA in 0.5 mA increments are used to control radio functions. Parameters
for dc control are set using the programming software. However, the accuracy of the adjustments may be
affected by line loads and installations. In order to work properly with varying line loads and dc remote
adapters, the time the current is present before allowing key-down may be programmed with the
software. Appropriate settings ensure the state of the remote adapter can be assured when a frequency
change current is asserted.
OTE: JU1 on the power I/O board (DPS) must be “out” for DC Control.
N
Optional Relay Control Kit
NOTE: These optional features require the XRC0001A Relay Control Kit and XAC0100A
Mounting Kit.
The CARD Suite programming software can be used to assign the type of configuration desired. It can
be configured as E&M control, local, or E&M with Tone control. Two pair of leads controls
communication between the IPE2500A and the base station. Maximum load ratings for each relay output
are 1 A @ 125 V ac and 2 A @ 30 V dc.
Local Control
For applications where the radio is connected directly to desk set units on-site, the unit must be
configured for local control. Also, a PTT and monitor relay must be programmed with the CARD Suite,
and these connections must be made to the relays.
E&M
The CARD Suite can be used to configure the IPE2500A for E&M control. The unit can be configured
for either E&M control or E&M with tone control. Two pairs of leads control communication between
the desk set and the base station. One pair is dedicated to audio TX/RX, the other pair controls the E&M
signaling.
The IPE2500A uses the M lead to signal when to transmit, and the E lead to detect when to receive. Note
that the E lead is not required. The M lead must be set on relay module using the CARD Suite software.
E Lead
In systems requiring full-featured E&M control, the input can be configured as an E lead to indicate an
unsquelched condition. The IPE2500A uses this input as a VOX indicator, so when asserted, generates a
VOX condition. However, the speaker squelch is operated by voice activity.
M Lead
A closure is needed to act as the M lead, which is the relay closure. The M lead will be closed depending
on the type of configuration and the type of transmission, only during a non-intercom transmission.
When configured as E&M control, the relay will be closed only when a transmission requiring
transmitter keying is needed.
When configured as E&M with Tone control, the relay will be closed whenever a non-intercom
transmission is done.
03/12 20
IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation
E&M with Tone Control
Used for transmitting control tones using an RF device in lieu of a telephone line. Two pair of leads
control the high level guard tone, function tone and low level guard tone. The tones are generated by the
IPE2500A to base stations via the E&M leads.
The M lead is used to assert PTT of the device, allowing transmission of the control tones to a remote
adapter with a receiving RF device. The unit must be configured for E&M with Tone control and M lead
must be set on relay mode. Note that the HLGT duration may need to be increased to allow the RF
device time to keep up and transmit to the receiving device.

N
OTE: The addition of the line select option to the IPE2500A allows the unit to control multiple base
stations with one unit using tone remote control. The option is not compatible with dc or local control
configurations.
Since the option is an ancillary device, some limitations are imposed on the operation of the unit. These
limitations include:
The LOTL detection and parallel status updating features of the IPE2500A are not available when
the multi-line select option is installed because the IPE2500A receives a sum of the select and
unselect audio and cannot distinguish the source of the audio.
During multi-select transmissions, the same control tones are used on each line. The unit is not
capable of generating different function tones on each line during a multi-select transmission.
The channel aliases are shared among all lines.
The volume control becomes a master volume for select and unselect audio. The relative level of the
unselect audio to the select audio can be adjusted during operation.
