4: Using Setup Mode for Configuration
XPort™ User Guide 36
Packing Interval: Packing Interval defines how long the unit should wait before
sending accumulated characters. This wait period is between successive network
segments containing data. For alternate packing, the default interval is 12 ms.
Trailing Characters: In some applications, CRC, Checksum, or other trailing
characters follow the end-of-sequence character; this option helps to adapt frame
transmission to the frame boundary.
Send Characters:
If 2-Byte Send Character Sequence is enabled, the unit interprets the
sendchars as a 2-byte sequence; if this option is not enabled, the unit
interprets them independently.
If Send Immediately After Characters is not set, any characters already in the
serial buffer are included in the transmission after a "transmit" condition is
found. If this option is set, the unit sends immediately after recognizing the
transmit condition (sendchar or timeout).
Note: A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout) Use this parameter to set an inactivity timeout. The unit drops the connection if there
is no activity on the serial line before the set time expires. Enter time in the format
mm:ss, where m is the number of minutes and s is the number of seconds. To
disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99
minutes, 59 seconds). Default is 0.
Send Characters You can enter up to two characters in hexadecimal representation in sendchar. If the
unit receives a character on the serial line that matches one of these characters, it
sends the character immediately, along with any awaiting characters, to the TCP
connection. This action minimizes the response time for specific protocol characters
on the serial line (for example, ETX, EOT). Setting the first sendchar to 00 disables
the recognition of the characters. Alternatively, the unit can interpret two characters
as a sequence (see Pack Control on page 35).
Telnet Terminal Type This parameter displays only if you enabled the terminal type option in Disconnect
Mode. If this option is enabled, you can use the terminal name for the Telnet terminal
type. Enter only one name.
If the terminal type option is enabled, the unit also reacts to the EOR (end of record)
and binary options, which can be used for applications like terminal emulation to IBM
hosts.
Channel (Port) Password This parameter appears only if the channel (port) password option is enabled in
Disconnect Mode. If the option is enabled, you can set a password on the serial port.
