Buffer Size
– Enter the maximum size (between 1 and 4095 bytes) allowed in
the response to a network client. The actual number of bytes sent may be
less if the Demark Timer expires before the serial butter is full. Enter 512
(typical) for this TIM application.
Demark Timer – Enter the maximum time (from 10 to 30,000 milliseconds)
that the TIM should wait for activity on the serial port to cease before sending
a response back to the network client (presuming that at least one byte was
received). Enter 50 (typical) for this TIM application.
Response Timeout – (This field is ignored unless the “Half Duplex” option is
set; it does not apply to this TIM application.) Enter the desired timeout (from
10 to 30000 milliseconds). If a response is not received from the serial port
within the specified time, the port is released and the terminal receiver will not
read any more serial data until the next request is received. Enter 1000
(typical) for this TIM application.
Serial Ports Table – The Serial Ports Table (brown background) is part of the
Terminal Server configuration. At least one row in the Serial Ports Table must be
configured for the Terminal Server to work properly.
COM Port
– Select the serial port (COM2 or COM3) from the drop-down list.
To avoid conflicts, this port must not be configured for any other use by the
TIM. Select “COM2” (typical) for this TIM application.
Baud Rate
– Select the desired baud rate (1200 to 115, 200) for the Terminal
Server port. Select “9600” (typical) for this TIM application.
Data Bits – Select the number of data bits (5 to 8) to use for the Terminal
Server port. Select “8” (typical) for this TIM application.
Parity – Select the parity for use with the port. Select “None” (typical) for this
TIM application.
Stop Bits – Select the number of stop bits for use with this port. Select “1”
(typical) for this TIM application.
Flow Control – Select the method for use with this port. Select “None”
(typical) for this TIM application.
