GENERAL INFORMATION
BEFORE INSTALLATION
Read this manual completely and gather all information
on the unit. Make sure that you understand it fully. Check
that your application does not exceed the safe operating
specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or
similar, where access is restricted to service personnel
only.
The power supply wiring must be sufficiently fused, and
if necessary it must be possible to disconnect manually
from the power supply. Ensure compliance to national
installation regulations.
This unit uses convection cooling. To avoid obstructing
the airflow around the unit, follow the spacing recom-
mendations (see Cooling section).
This modem is for restricted access area use
only.
BEFORE MOUNTING, USING OR REMOVING THIS UNIT
Prevent access to hazardous voltage by disconnecting
the unit from power supply. Do not open connected unit. Hazardous
voltage may occur within this unit when
connected to power supply or TNV circuits.
CARE RECOMMENDATIONS
Follow the care recommendations below to maintain full
operation of unit and to fulfil the warranty obligations.
This unit must not be operating with removed covers or
lids.
Do not attempt to disassemble the unit. There are no
user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling
above the specification may cause damage to internal
circuit boards.
Do not use harsh chemicals, cleaning solvents or strong
detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent
proper operation.
Do not expose the unit to any kind of liquids (rain,
beverages, etc). The unit is not waterproof.
Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connec-
tors as well as other mechanical part may be damaged.
If the unit is not working properly, contact the place of
purchase, nearest Socomec distributor office or Socomec
Tech support.
Maintenance
No maintenance is required, as long as the unit is used
as intended within the specified conditions.

INTRODUCTION
The modem RS232 <=> RTC <=> RS485 is designed to
satisfy industry’s demands on reliability and functiona-
lity in environments with high levels of interference. It has
an RS232 interface and works as a calling / answering
modem on 2-wire Leased Lines. The product can use
4-wire Leased Lines. It can handle rates up to
115.2 kbit/ s on the terminal side and up to 33.6 kbit/ s on
the line side.
Specific parameters can also be set in hardware using
DIP-switches.
The modem is equipped with transient protection on the
line side and a “watchdog” that monitors and automa-
tically resets the modem in the event of a fault. These
functions together with the possibility for remote confi-
guration makes the modem perfect for installation at
unmanned sites and prevents the need of costly service
trips.
The modem also has password protection and dial-back
security to ensure that only authorised users can commu-
nicate with the modem.
The modem is intended for mounting on a 35 mm DIN-
rail, where the modem is attached and locked in a single
action.
In the product there is also an RS485 interface allowing
multidrop connections to many types of industrial
equipment.
It also has a single digital input and output. The input
can be used to trigger a number of different user defined
events. The output is a relay that can also be triggered by
a number of different user defined events. Both the digi-
tal input and output are galvanically isolated from the
rest of the modem.

FCC Part 15.105 Notice
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful inter-
ference in a residential installation.
This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• reorient or relocate the receiving antenna,
• increase the separation between the equipment and
receiver,
• connect the equipment into an outlet on a circuit
different from that to which the receiver is connected,
• consult the dealer or an experienced radio / TV techni-
cian for help.
