ACE9092
RS232/RS485 Converter
Description and Dimensions
DE80038
The terminal block for RS232 link is limited to 10 m (33 ft)
The Female 9-pin sub-D connector attaches the two-wire RS485 network to
the power supply
One screw-type male nine-pin sub-D connector is supplied with the converter.
Power-supply terminal block
1 Distributed power supply voltage selector switch, 12 V DC or 24 V DC
2 Protection fuse, unlocked by a 1/4 turn
3 LEDs:
b ON/OFF: If ACE9092 is energized, this is ON
b Tx: ON if the RS232 sending by ACE9092 is active
b Rx: ON if the RS232 receiving by ACE9092 is active
4 SW1, parameter setting for two-wire RS485 network polarization and line
impedance matching resistors
Function SW1/1 SW1/2 SW1/3
Polarization at 0 V via Rp –470 Ω ON
DE80022
Polarization at 5 V via Rp +470 Ω ON
Two-wire RS 485 network impedance
