Flow Control

Flow control manages data flow between devices in a network to

 

 

 

ensure it is processed efficiently. Too much data arriving before a

 

 

 

device is prepared to manage it causes lost or retransmitted data. The

 

 

 

default setting is None.

 

 

 

 

 

 

Baud Rate

The unit and attached serial device, such as a modem, must agree on

 

 

 

a speed or baud rate to use for the serial connection. Valid baud rates

 

 

 

are 300, 600, 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600,

 

 

 

115200, or 230400. For baud rates 460 and 921 Kbps, the CPU

 

 

 

Performance Mode must be set to High.

 

 

 

 

 

 

Data Bits

Indicates the number of character bits. 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 the checkbox to enable packing on the WiBox 2100E.

 

 

 

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 the end of data collection

 

 

 

to the WiBox 2100E. 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 Immediate

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 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.
