Installation

ACE9092

RS232/RS485 Converter

Function

PE50035

The ACE9092 converter connects a master/central computer equipped with a

V24/RS232 type serial port (as a standard feature) to stations connected to a two-

wire RS485 network.

After you set the operating parameters, the ACE9092 converter uses two-way

simplex (half-duplex, single-pair) transmission to provide conversion, network

polarization, and automatic frame dispatching between the master and the stations

without the need for any flow control signals.

The ACE9092 converter also provides a 12 V DC or 24 V DC supply voltage for the

distributed power supply of the Sepam™ ACE9492, ACE959 or ACE969 interfaces.

The communication settings should be the same as the Sepam™ and supervisor

communication settings.

HAZARD OF ELECTRIC SHOCK, EXPLOSION

OR ARC FLASH

b Only qualified electrical workers should

install this equipment. Such work should

be performed only after reading this entire

set of instructions.

b NEVER work alone.

b Before performing visual inspections,

tests, or maintenance on this equipment,

disconnect all sources of electric power.

Assume that all circuits are live until they

have been completely de-energized,

tested, and tagged. Pay particular

attention to the design of the power

system. Consider all sources of power,

including the possibility of backfeeding.

b Always use a properly rated voltage

sensing device to confirm that all power is

off.

b Screw tight all terminals, even those not in

use.

Failure to follow these instructions will result

in death or serious injury.
