A Tunnel in Accept Mode can be started in a number of ways:
Disabled: never started |
Enabled: always started |
Any Character: started when any character is read on the Serial Line |
Start Character: started when the Start Character is read on the Serial Line |
Modem Control Asserted: started when the Modem Control pin is asserted on the Serial Line |
Modem Emulation: started when triggered by Modem Emulation. Connect mode must also be set to Modem Emulation |
The Local Port can be overridden and by default is 10001 for Tunnel 1, 10002 for Tunnel 2, and so on.
The Protocol used on the connection can be one of TCP, SSH, Telnet, or TCP w/AES. If security is a concern it is highly recommended that SSH be used. When using SSH both the SSH Server Host Keys and SSH Server Authorized Users must be configured.
The Flush Serial Data boolean specifies to flush the Serial Line when a connection is made.
For debugging purposes, the Block Serial Data and Block Network Data booleans can be toggled to discard all incoming data on the respective interface.
The TCP Keep Alive timer specifies how often to probe the remote host in order to keep the TCP connection up during idle transfer periods. Enter 0 to disable.
The CP Set Group identifies a CP or CP Group whose value should change when a connection is established and dropped. On Connection specifies the value to set the CP or CP Group to when a connection is establised and On Disconnection specifies the value that should be used when the connection is closed.
The Password can be up to 31 characters in length and must contain only alphanumeric characters and punctuation. When set, clients must send the correct password string to the unit within 30 seconds from opening network connection in order to enable data transmission. The password sent to the unit must be terminated with one of the following: (a) 0x10 (LF), (b) 0x00, (c) 0x13 0x10 (CR LF) (d) 0x13 0x00. If Prompt for Password is set to On, user will be prompted for password upon connection.
