Converter / Amplifier CAMO
M98237901-20-12C
M54090 - CAMO
OPTOISOLATED MULTISERIE
AMPLIFIER CONVERTER
1.- Features
CAMO is a protocol converter that allows the
communications between RS-232 master and
until 32 peripherals in RS-485 or till 10 devices
in
RS-422. Allows to amplifier the
communications signal in RS-485 bus to reach
more length of wiring between the master and
the different peripherals. The function of
converter or amplifier is automatically done by
the device by the communications frames
detected.
2.- Caution
Before making any maintenance
operation, connection modification,
repair, etc., you must disconnect the
device from all power supplies. If you
suspect an operational fault in the unit or in its
protection system, remove the unit from service.
Note that when the instrument is switched on, the
terminals may be dangerous when touched an
opening or removing parts may access dangerous
areas. Therefore, the equipment must not be used
until it is properly installed.
The equipment must be connected to a power
supply circuit protected with gl (IEC 269) or type M
fuses between 0.5 and 2 A. It must have an
overload/short circuit switch or equivalent device in
order to disconnect the equipment from the power
supply system. An earth leakage switch or similar
device must be fitted to disconnect the equipment
from the power supply system. The power supply
circuit are connected with a cable with a minimum
diameter of 1 mm².
3.- Installation
Installation of equipment is done on a DIN rail,
leaving all the connections inside an electrical
panel. The unit has a supply LED indicator next
to the power connector that indicates its status.
4.- Connection
Use only the pins indicated for each
wiring. Use more pins than listed will
cause device malfunction.

DB9 female connector (located in the supply
side) uses pins 2, 3 and 5 for RS-232 input
(see table 1).
The RS-485 output connection is possible to do
from the DB9 connector (see table 2) or from
the A-B connectors located beside of the
transmission/reception communications LED.

4.2.- RS-485 to RS 485 Amplifier
To use as amplifier you have to connect the
input in pins 5, 8 and 9 (see table 1).
The amplified RS-485 output can be wired from
DB9 as indicates the table 2 (see picture 1).
The RS-485 output through terminals A-B is
like indicates picture 2.
