2. Normally the Supervisor Password can be entered at any port in order to gain access to Supervisor Level commands Note that if you wish to completely deny a port s access to Supervisor Mode even with the Supervisor Password the Port Parameters menus P can be used to disable the Supervisor Mode at ports 3 through 8 The Supervisor Mode cannot be disabled at System SetUp Ports 1 and 2 Note that 1f the unit 1s reset to default parameters all ports will revert to the default state where Supervisor Level commands are available to all ports without password protection APS 8M User s Guide 5 5 2 The Port Passwords The Port Passwords or User Passwords allow system administrators to restrict access to a specific group of ports When the APS 8M command mode is accessed with a Port Password users may only connect to the RS232 Ports to which they have been granted access and review configuration parameters for those ports Port Passwords do not grant access to APS 8M configuration commands The configuration menus P for each RS232 port allow a Port Password to be assigned to each individual port In order to allow a Port Password to grant access to a group of APS 8M ports the same Port Password is assigned to each port in the group For example if the Port Password test is assigned to ports 3 4 and 5 then when test is entered at the Password Prompt the user will only be able to connect to ports 3 4 and
3. Enter Where xx and XX are two port names or numbers The APS will display the numbers of the two connected ports Example To connect Port 5 to Port 6 invoke the following command at a port with Supervisor Level command capability C 5 6 Enter When the C command specifies the port name it is only necessary to enter enough letters to differentiate the desired port from other ports Type an asterisk to represent the remaining characters in the port name For example to connect your resident port to a port named SALES the connect command can be invoked as C S providing no other port names begin with the letter S Operation 8 1 1 2 Disconnecting Ports There are three different methods for disconnecting ports the Resident Disconnect the Third Party Disconnect and the No Activity Timeout Providing the Timeout feature is enabled a No Activity Timeout will disconnect resident ports or third party ports Note When Any to Any Mode Buffer Mode or Passive Mode are selected Option 74 in the Port Parameters Menu determines how the DTR signal will react when the port disconnects The DTR signal can either be held low held high or pulsed and then held high 1 Resident Disconnect Disconnects your resident port from another port For example if you are communicating via Port 3 and Port 3 is connected to Port 4 a Resident Disconnect would be used to disassociate the two ports The APS offers two different R
4. Establishes a bi directional connection between two ports For more information and command line examples please refer to Section 8 1 There are two different types of port connections Resident Connect If the C command specifies one port name or number your resident port will be connected to the specified port Third Party Connect If the C command specifies two port names or numbers the unit will connect the two ports indicated A Third Party Connect command must be issued from a third port with Supervisor command capability User ports cannot initiate a Third Party Connect Note Ports with User command capability can only connect to ports that share the same Port Password Ports with Supervisor command capability are allowed to connect to all other ports Availability Supervisor User Format C x x Enter Where x is the number or name of the port s to be connected Response Verbose Connected xx when a Resident Connection is initiated the APS will also display the currently selected Resident Disconnect Sequence for your port Terse 1 CP Copy RS232 Port Parameters Allows quick set up when all APS RS232 ports will be configured with the same or similar parameters When the CP command is invoked the APS will display a menu that is used to select common port parameters which can then be copied to all APS RS232 ports Note that the Copy Command will not change restricted parameters at
