CCM 1010 (MW10)
1. General description
The CCM 1010 contact closure multiplexer system
can transmit eight independent contact closure
signals unidirectionally over either one optical fiber
or a serial data link (RS-232). A CCM 1010 TX/RX
combination uses an optical wavelength of 850 nm
over multimode fiber.
Front panel LEDs indicate DC power good, correct
transmission
framing
and
correct
receiver
synchronisation.
CCM 1010 equipment comes in the form of rack-
mountable 7TE modules to be slotted into a TKH
Security MC 11 or similar power supply cabinet, or
as stand-alone units (option /SA) needing separate
power supplies PSA 12 DC.

3. Installation instructions
3.1 General
- Insert the units into an appropriate MC 11 or
similar power supply cabinet (and/or connect stand-
alone units to their power supplies) and connect
appropriate cabling. Pin assignments are listed in
section 5.
- After switching on the system, check whether all
LEDs glow green. If the FR LED on the CCM TX
is red, that unit is faulty. If the SYNC LED on the
RX lights red while the FR LED glows green,
check the optical link first.
3.2 Link type
The unit tries to establish and use a link type based
on link input measurements (default autodetect
mode; it holds on to an interface as long as signal is
present). To permanently select either the optical or
the RS-232 link, internal dip switches can be set.
To access these switches, take out the front panel
Phillips head screws indicated in figure 1 and slide
out the front panel/circuit board assembly. Dip
switches S1/S2 select between autodetect, the serial
link and the optical link (see figure 2 and table 2).
