Function of the converter:
The Espa 4.4.3 to Espa 4.4.4. converter acts as a gateway between older Espa
4.4.3. systems and newer Espa 4.4.4. systems, creating the possibility to read Espa
4.4.3 messages from an older system and sent them to a Espa 4.4.4. installation.
The converter is connected to the PABX with:
M and M’ (Mouth contact)
E and E’ (Ear-contact),
A and B (600 ohm line)
When connecting the PABX to the converter make sure that the M and the E
contact are crossed. The Mouth contact for the PABX is like the Ear contact of the
converter.

If a call is received via Espa 4.4.3. it will be translated to an Espa 4.4.4 call and
sent. The status that is received via Espa 4.4.4. will be forwarded to the Espa 4.4.3.
side, generating a ‘paged‘ or ‘absent‘ call on the Espa 4.4.3. side.
If the forward of the status is not needed (or the ESPA 4.4.4. system does not
generate a ‘paged‘ or ‘absent‘ status, the status generated on the ESPA 4.4.3. side
can be fixed to ‘paged’ .

Connecting to an existing Espa 4.4.3. installation:
The converter uses PhotoMos technology for the M contact. This contact is used in
Espa 4.4.3 to indicate to the PABX that all digits are received, and also to indicate
the Absent/Paged status.
The converter also has a build in supply to power the E contact. The supply is
limited to 12V 8mA. So if the PABX also supplies the E contact that should not
cause any problem. The current will be limited automatically. Please check the
polarity (+ and -) of the E contact before connecting the converter. A faulty polarity
will not harm the converter, but if the converter sends + 12V and the PABX sends –
12V, both signals end up as 0V, and are not detected by the converter.
The AB line are the lines over which the actual DTMF digits are sent from the PABX
to the converter.
If the total amount of digits is received by the converter, it will generate a ‘all digits
received’ puls on its M contact, indicating to the PABX that the digits are received. If
the amount of DTMF digits is insufficient, a time-out status will occur,

2: E-
3: A
4: B
5: M (+)
6: M’ (-)
The E+ and E– inputs are connected to the M+ and M–
output contacts of the PABX. When the PABX wants to send
a message it will start by raising the M contact, connecting
M+ and M-. If the M+ and M– outputs of the PABX are not
isolated, or send power over the M+ and M- contacts, then
please note the polarity of that power. Please note that If the
PABX sends +10V to +16V over the M contact, the polarity is
important, because the converter uses its own power
generator of 12V to read the status of the M contact. If both
are 12V and the polarity is wrong, no M contact is detected.
Then switch the M+ and M– contact and it should be ok.
Internally the detector runs from 10V to 48V DC.
The polarity of the M+ and the M– contact is not important.
The contacts are used by the converter to indicate a status
present/paged/absent to the PABX on its M+ and M–
terminals.
The A and B terminals are used to send DTMF data to the
converter. If the PABX occupies the converter, the converter
can be programmed to generate a dailtone. Or a busy tone in
case the pager is absent.

LED indicators for ESPA 4.4.3:
Status: Short green flash every second:
The converter is in idle state, no errors detected on ESPA 4.4.3 or
ESPA 4.4.4. side. No calls present in buffer.
Long green flash every second:
The converter is in idle state, no errors detected on ESPA 4.4.3. or
ESPA 4.4.4. side. But there are calls to be transferred in the buffer.
Short red flash every second:
An error is detected.
Long red flash every second:
An error has occurred, and the error is remaining.
Short orange flash:
DTMF data is received.
MThis LED indicates that the converter has activated the M contact .
EThis LED indicates that the E input of the converter is activated by the PABX..

Connecting the power:
The power supply of the converter is 12V DC.
Please us the supplied power supply.
Manual for the Espa 443 to 444 converter page 9 Date: 23 Februari 2014
Connecting the Espa 4.4.4. output:
The converter uses a standard 9 pole SUBD connector with RS232 to
communicate with its peripheral (PC or other system).
The pin-layout is::
Pin 2: TxD
Pin 3: RxD
Pin 5: GND
Pin 7: CTS
Pin 8: RTS
The pin 7 and pin 8 are used for hardware handshake. With a software tool
you can select if the hardware handshake is used or not.
We strongly advise to use the locking screws to connect the plug to the
converter.

Connecting the Espa 4.4.4. output:
The TxD and RxD leds indicate the communication on the RS232 serial lines
to the ESPA 4.4.4. device. If data is sent, the red led lights up shortly, if data is
received the green led lights up shortly.
