Pack Control

 

 

 

Enable Packing

Select to enable packing on the XPress DR+. Disabled by

 

 

 

default.

 

 

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.

 

 

 

 

 

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 XPress DR+. 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.

Flush Output Buffer (Network to Serial)

With Active Connect

Select Yes to clear the output 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 output 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 output buffer when the network

 

connection to or from the device is disconnected. The default

 

setting is No.

3.When finished, click the OK button.

4.To save and reboot, click Apply Settings on the main menu.
