DTMF/H.E.A.R. Functions
As noted in the “Operation” section of this manual, the IPE2500A must be manually placed in “mute”
mode when used in a H.E.A.R. operation. This requires that one of the function keys to be programmed
for mute operation. While in CARD Suite under the IPE2500A programming archive, select the
Programmable Buttons tab. Select PB1–PB4 from either the Programmable Button Selection or the CTL
+ Programmable Button Selection (CTL + the programmable button means that the CTL button must be
depressed while pressing the assigned mute button). Select the Mute function from the drop-down box.
Be certain that the “mute duration” remains at “0” (on/off activation).
The parameters listed below are also programmable via CARD Suite Programming software. Refer to
the CARD Suite Help file for detailed programming instructions.
DTMF Decode Inter-digit Time - Allows the decoder to qualify the duration of a DTMF digit and to
further ensure that the DTMF sequence meets the desired customer specifications.
Minimum and Maximum Digit Count - Allows the decoder to ignore those DTMF sequences that are
not actual ID’s or ID’s of interest; the IPE2500A is capable of decoding one to eight digits.
DTMF Decode Alias - Provides alphanumeric display of the transmitting radio’s ID.
H.E.A.R. System Base ID - This ID is used to determine whether the incoming DTMF sequence is to
unmute the desk set speaker.
H.E.A.R. System Base ID Size - Allows proper comparison of an incoming DTMF sequence with the
programmed ID.
H.E.A.R. System Flags - Include audible alert on/off and duration of the audible alert.
H.E.A.R. System Alert Relay - When an incoming DTMF sequence matches the H.E.A.R. system base
ID, this optionally installed relay is asserted.
Audio Accessory/RS-232 Port
Use the eight-pin audio accessory/RS-232 port to connect a PC to the IPE2500A with the XAC0004A
Programming Cable in order to use the CARD Suite Programming software. See the CARD Suite
Software Help file for instructions on set up and programming options.
After programming is complete, connect an audio accessory, such as a desk microphone, gooseneck
microphone, boom microphone, headset, or footswitch, if desired. The microphone input type is passive,
with an input impedance of greater than 2k ohms and a nominal input level of −20 dBm.
Refer to the audio accessory/RS-232 port pinout on page 7 in the “Connectors” section of this manual.
