Serial Port Profiles

The 

 tab configures all the serial port hardware connection information. The window below 

shows an SDS1 model; your 

 tab might display a subset of the parameters described, 

depending on the IOLAN model and supported hardware.

Configure the following parameters:

Specifies the type of serial line that is being used with the IOLAN.
Data Options: EIA-232, EIA-422, or EIA-485. 

 

SCS/STS/MDC models support only EIA-232.
Default: EIA-232

Specifies the baud rate of the serial line; keep in mind that speed is affected by 

the length of the cable. You can also specify a custom baud rate. When you 
enter a custom baud rate, the IOLAN will calculate the closest baud rate 

available to the hardware. The exact baud rate calculated can be viewed in the 

 statistics.

Range: 50-230400, custom supports 50-1843200
Default: 9600

Specifies the number of bits in a transmitted character.
Default: 8

Specifies the type of parity being used for the data communication on the serial 
port. If you want to force a parity type, you can specify 

 for 1or 

 for 

0. 
Data Options: Even, Odd, Mark, Space, None 
Default: None

Specifies the number of stop bits that follow a byte. 
Data Options: 1,1.5, 2. 1.5 is only available on the 1-port and 2-port models, 

but not on the modem line (Serial Port 2) of the SDS1M model.
Default: 1
