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, 19200, 38400, 57600, and 115200
baud. The 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 XPress device server.
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 XPress device server. 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 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.
