default setting is 9600.

Data Bits

Indicates the number of bits in a transmitted data package.

The default setting is 8.

Parity

Checks for the parity bit. The default setting is None.

Stop Bits

The stop bit follows the data and parity bits in serial

communication. It indicates the end of transmission. The

default setting is 1.

Pack Control

Enable Packing

Select to enable packing on the SDS.

Two firmware-selectable packing algorithms define how and

when packets are sent to the network.

The standard algorithm is optimized for applications in which

the unit is used in a local environment, allowing for very small

delays for single characters, while keeping the packet count

low.

The alternate packing algorithm minimizes the packet count

on the network and is especially useful in applications in a

routed Wide Area Network (WAN). Adjusting parameters in

this mode can economize the network data stream.

Disabled by default.

Idle Gap Time

Select the maximum time for inactivity. The default time is

12 milliseconds.

Match 2 Byte Sequence Use to indicate the end of a series of data to be sent as one

group. The sequence must occur sequentially to indicate end

of the data collection to the SDS. The default setting is No.

Match Bytes

Use to indicate the end of a series of data to be sent as one

group. Set this value to 00 if specific functions are not needed.

Send Frame Only After the detection of the byte sequence, indicates whether to

send the data frame or the entire buffer. Select Yes to send

only the data frame. The default setting is No.

Send Trailing Bytes Select the number of bytes to send after the end-of-sequence

characters. The default setting is None.

Flush Input Buffer (Serial to Network)

With Active Connect

Select Yes to clear the input buffer with a connection that is

initiated from the device to the network. The default setting is

No.

With Passive Connect

Select Yes to clear the input buffer with a connection initiated

from the network to the device. The default setting is No.

At Time of Disconnect

Select Yes to clear the input buffer when the network

connection to or from the device is disconnected. The default

setting is No.
