Configuring Serial Ports

The AADvance controller provides up to six serial communication ports, two for each 9110 processor module present. Each pair of serial ports is identified as
Sn
-1 and
Sn
-2 where
n
 indicates the processor module:
  • [S1-1 and S1-2]
  • [S2-1 and S2-2]
  • [S3-1 and S3-2]
The serial port settings define the protocol type and the data characteristics of the individual serial ports.
Setting
Description
Name
Name of the serial port.
Baud Rate
The baud data transfer rate, in milliseconds. Possible values are 1200, 2400, 4800, 9600, 19200, 38400, 57600, 76800 or 115200; The default value is 19200.
Data Bits
The number of bits representing one character of data in a transmission. Possible values are 5, 6, 7, and 8. The default value is 8.
Parity
The type of parity used. Possible values are
None
,
Even
, and
Odd
; the default value is
None
.
Stop Bits
The number of stop bits used to indicate the end of a transmission. Possible values are 1 or 2; The default value is 1.
Type
The protocol to use for the serial port. Possible protocols are the following:
  • RS485fd
    - Full-duplex, 4-wire connection with separate buses for transmit and receive
  • RS485fdmux
    - Full-duplex, 4-wire connection with separate buses for transmit and receive and tri-state outputs on the transmit connections
  • RS485hdmux
    - Half duplex, 2-wire connection
The default property is
RS485hdmux
.
fd
 indicates full duplex and
hd
 indicates half duplex.
Comment
Plain text
TIP: Most systems use two bits after each data byte. These bits are either a parity bit (odd or even) and one stop bit, or no parity and two stop bits.
To configure serial ports
  1. In the
    Communication View
    , expand the required controller, and then double-click the
    Serial
     element.
    The
    Communication
    property page displays the serial ports.
  2. In the
    Communication
    property page, specify the properties for the individual serial ports.
