Snom D7C User Manual Setting up the expansion module
Connecting the Snom D7C to a Snom phone
The connectors are marked A, B, and C. Connectors A and B are used to attach the footstands of D7C
and the phone, connector C is used to connect the footstands of two D7Cs:
◦A: connecting to D717, D735, and D765.
◦B: connecting to D785. There is also a smaller plate marked B to connect the D7C and the
D785 more securely.
◦C: connecting a D7C to another D7C.
You can connect up to three Snom D7Cs to one of the supported Snom phones. The rst expansion
module is supplied with power by the phone via the module's USB cable. The second module is
supplied with power by one of the separately available power adapters. The third expansion module
is supplied with power by the second module via the third module's USB cable.
Note: In some cases, e.g. if you connect a device requiring a lot of power to the USB
port of the D7C, you may also need to attach a power adapter to the third and the rst
module in the daily-chain.
1. Place a soft cloth on the desktop so that the display does not get scratched or otherwise damaged
if you lay the device down.
2. Attach the respective footstand to the D7C expansion module and to the phone.
3. Place the USB cable of the D7C into the cable guide (Fig. 1).
Fig. 1
4. Connect the expansion module to the phone, as shown in Fig. 2. If the phone has two USB ports
(Fig. 3), either one can be used.

securely into place, push the three levers on the connector towards the footstand of the phone
until you hear each one click into place.
7. D785 only. Place a soft cloth on the desktop and turn phone and D7C backside up. On either side
of the small plate marked B there is a ridge (Fig. 6) that ts into the slideguides on the footstands.
Insert the ridges into the slideguides of the footstands of phone and D7C and slide the connector
down toward the tips of the "legs" (Fig. 7).
Fig. 6 Fig. 7
Connecting two or three D7Cs to a Snom phone
Do not use a USB hub (Fig. 8). If the phone has more than one USB port, do not connect expansion
modules to more than one port (Fig. 9). The D7Cs must be daisy-chained. If they are not, the phone
will not be able to identify the function keys on the modules, rendering them inoperable.
Fig. 8 Fig. 9
1. Connect the modules to each other rst. If a module is connected to the phone already, connect
the second and third module to each other.
2. Important note: Attach a power adapter (available separately) to the second module and to a wall
outlet before connecting the daisy-chain to the phone or the second / second and third module to
the D7C already connected to the phone (Fig. 10).

the USB adapter of the wireless headset into the USB port on the last module in the chain,
If the Snom phone has two USB ports, the USB adapter of the wireless headset can be inserted into
the USB port on the expansion module or into the free USB port on the phone.
