Optional Data 
Port Module
7.21 All 
IMX 1Zline and 24-line keysets may he
equipped with optional Data Port Modules (refer to RR-
PLACEkENT PARTS for the part number). The Data
Port Module contains a four-conductor modular jack
that can be used to connect 
either a data device (such as a
personal computer with a direct-connect modem) or an
LRA and an external signaling device (such as a loud
bell, horn, flashing light, etc.) to the 
keyset.
7.22Install the Data Port Module as outlined below.

Unplug the line cord 
from its modular jack.
Remove the 
lo-pin shorting plug located on the
keyset control card.
NOTE: The back cover of the keyset does not
need to be removed in order to reach the shorting
plug.
Save the shorting plug by taping it to the bottom
cover of the 
keyset or to the inside of the base-
plate. The plug must be replaced if the Data Port
Module is later removed.
Align the Data Port Module over the appropriate
scxew holes (see Figure 3-45) on the back cover
of the 
keyset and insert the screws (do not over
tighten).
Plug the Data Port Module cable into the pins on
the 
keyset control card (where the shorting plugwas previously located). Make sure the cable
connector is securely seated.
Place jumper straps 
SPl, SP2, SP3, and SP4 onthe Data Port Module in the appropriate posi-
tions. Depending on how the Data Port Module
will be used, refer to one of the two possible 
set-
tings outlined in Figure 3-45.

refer to paragraphs 7.23 through 7.25.If connecting a loud 
tinging adapter and an
extend signaling device, refer to paragraphs
7.26 through 7.28.7.23 To connect a modem-equipped data device:
The optional Data Port Module can be used to connect a
data device (such as a personal computer) equipped with
a 
directconnection modem to a keyset. The data device
can be used with the 
keyset to communicate withremote
data equipment over voice channels being used for CO
or intercom calls. The data device’s modem must be ex-
ternally powered (or capable of operating on 
2omA of
loop current) and have an 
RJll CO trunk interface.
7.24The data device can be activated using the 
keyset
or an auto-dial modem. (For more details and an expla-
nation of monitoring or transferring the data connection,
refer to page 4-101 in
FlMWRES). The data device is
disconnected whenever one of the following occurs: the
modem attached to the 
keyset disconnects from the call,
the called modem disconnects from the call, or the data
connection is transferred to 
the keyset’s primary voice
path and the call is disconnected.

7.26To connect a Loud Ringing Adapter (LRA):
The optional Data Port Module can be used to connect
external signaling equipment such as loud bells, horns,
flashing lights, etc. to a 
keyset. This application is useful
in areas where the normal ring tone of the 
keyset cannot
be heard, such as warehouses and loading docks. The
signaling device follows the normal ringing patterns of
the 
keyset.
NOTE 
Since handsfree intercom calls may be difficultto hear in noisy areas, 
keysets with LR& installed
should be programmed for handsfree disable so that us-
ers are alerted to incoming intercom calls by continuous
double ring tones. (Refer to 
FEHURES, page 4-55.)
7.27An electromechanical 
LRA device is placed be-
tween the 
keyset Data Port Module and the external sig-naling equipment to provide the necessary interface
relay. Refer to page 2-23 for LR4 device specifications
and recommendations. A diagram of a typical set-up is
shown in Figure 3-46 below.
7.28Install the 
LRA as follows:
(1)Using 24AWG wire, connect the LRA device in-
put (coil circuit) to the 
RED and GREEN wires
(2)
(3)
(4)
(5)
on a modular jack assembly. Some devices re-
quire that polarity be observed between the 
LRA
input and the modular jack.
NOTE In order for the LRA device to operate
properly, the maximum 
resistance from the mod-
ular jack to the 
LRA should be kept under 100
OIlIllS.
Attach a mod-to-mod line cord to the modularjack assembly and to the modular jack on the
keyset’s Data Port Module.
Ensure that the jumper straps on the Data Port
Module are set in the proper 
LRA positions. Re-
fer to Figure 3-45 on the previous page.
Connect the LRA device output (contacts) to the
signaling device according to the manufacturer’s
instructions. Use the appropriate gauge wire for
handling the current/voltage rating of the signal-
ing device.
Plug the 
keyset line cord into the modular jack on
the back of the 
keyset and reattach the baseplate.

SIGNAL DEVICE
(e.g., bell)
NOTE Each time the keyset rings, the Data Port Module provides 20-26mA of loop current to the LRA. This
causes the LRA contacts to close and activates the signaling device. The LRA is not affected by the ring tone
or the ringer volume of the 
keyset. The LRA must be capable of operating on 2OmA current (approximately
2OVDC).

Keyset Installation
7.33Install all Inter-Tel/DVK keysets as follows:
NOTE: For information on installing the GX and GMX
keysets, see appendixes A and B in the back of this
manual.
(1)Before mounting the modular jack assembly andconnecting the 
keyset, measure the voltage on
the RED terminal of the modular jack assembly
with respect to the GREEN terminal. (The “com-mon” probe of the voltmeter is placed on the
GREEN terminal.) It must measure 
+3OVDC
(f2.OVDC). If -30VDC is measured, check the
cabling for a reversed pair.
ICAUTION
If the power pair (W/BL, BL/W) is reversed, in-
stalling a 
keyset will open the fuse (or associated
thermistor) on the KSC-D. If the card has a fuse,this affects operation of all 
keysets, DSWBLFUnits, and Attendant Computer Consoles con-
nected to that card.
