4.5.3 Serial (RS485 Serial Port)
These pages provide configurations for the iServer’s serial port as well as different
techniques for bridging data between serial and Ethernet ports (see
Figures 4.6
through 4.10
). Fields are described below.
The RS485 Service Port Tab as shown in
Figure 4.6
will appear only for
option C4EIT.
For the iSeries EIT option the following parameters: 9600,O,7,1,none are
fixed and the device must be set to these parameters.
For EIT option there will be no tab.

Baud Rate –
This indicates the speed of the iServer’s serial port. Options are
300,
600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400,
and
460800
bits/s. The default is
9600
bits/s.
iSeries device maximum Baud Rate is 19.2 kb/s
Data Bits –
This indicates the number of bits in a transmitted serial packet. Options
are
7
and
8
. The default is
7
.
Parity –
This checks the serial packet for the parity bit. Options are
Even, Odd,
and
None
. The default is
Odd
.
Stop Bit –
This indicates the end of transmission. Options are
1
and
2
. The default is
1
.
Flow Control –
This handles the data flow between the iServer and the attached serial
device to ensure it’s processed efficiently. Too much data arriving before the device
can handle it causes lost data. Options are
Software
also called Xon/Xoff (using Tx
and Rx pins), and
None
. The default is
None
.
