gefran AFE200 4 Series Instruction Manual page 125

14 - COMMUNICATION
The AFE200 is provided with a standard port (9 pole sub-D connector: XS) for connecting the RS485
serial line used for AFE-PC point-to-point communication (via the GF-eXpress configuration software)
or for the multidrop connection.
The RS485 serial line format is: 8 data bits, no parity and one stop bit.
14.1 - COMMUNICATION/RS485
Menu PAR Description
14.1.1 3800 Drive address
Setting of the address to which the AFE responds when connected to the RS485 se-
rial line.
Menu PAR Description
14.1.2 3802 Serial baudrate
Setting of the RS485 serial communication speed (Baud Rate).
0 9600
1 19200
2 38400
Menu PAR Description
14.1.3 3810 Serial parameter
Setting of the format of the RS485 serial communication data.
0
None,8,1
1 None,8,2
2 Even,8,1
3 Odd,8,1
Menu PAR Description
14.1.4 3804 Serial protocol
Setting of the serial communication protocol:
0 Modbus
1 Jbus
Setting to 0 selects the Modbus RTU (Remote Terminal Unit) serial communication
protocol.
Setting to 1 selects the Jbus serial communication protocol. The Jbus protocol is func-
tionally identical to the Modbus, except for the different numbering of addresses: in the
Modbus these start from zero (0000 = 1st address) while in the JBUS they start from
one (0001 = 1st address) and maintain this difference throughout numbering.
Menu PAR Description
14.1.5 3806 Serial delay
Setting of the minimum delay between the AFE receiving the last byte and starting
its response. This delay avoids conflicts on the serial line when the RS485 interface
that is used has not been pre-set for automatic Tx/Rx switching. The parameter only
concerns the use of the standard RS485 serial line.
