1. 6 2 CPM Series Control Port Managers User s Guide Operation P 6 2 Third Party Disconnect A Third Party Disconnect is used to disconnect two ports by invoking the D command at a third port For example if you are communicating via Port 1 and you wish to disconnect Port 3 from Port 4 a Third Party Disconnect would be used a The D Disconnect command can be invoked by any port that has been granted access to All commands Administrator b The D command line can specify both connected ports or either of the two connected ports For example if Port 3 is connected to Port 4 and Port 1 has access to All commands the user can invoke one of the following commands at Port 1 D 03 04 Enter or D 03 Enter or D 04 Enter No Activity Timeout Providing the Timeout Disconnect feature has been enabled for either connected port the No Activity Timeout can be used to disconnect Resident Ports or Third Party Ports a The Timeout Feature is enabled and defined by invoking the P command to access the Port Configuration Menu for the desired port Option 9 is used to enable or disable the Timeout Feature and Option 10 is used to define the Timeout Period b When the Timeout Feature has been enabled the port will automatically disconnect when no additional data is received for the defined Timeout Period The default Timeout Period is 5 seconds Defining Hunt Groups A Hunt Group creates a situation w2. Buffered Ports The CPM has 256KB or 512KB of non volatile dynamically allocated buffer memory This prevents data overflow during communication between two ports operating at dissimilar baud rates Modem Communication The CPM can either be controlled by a local PC that communicates with the unit via cable or controlled via modem by a remote PC ProComm or another communications program is used to send commands to connect ports or display status All devices connected to the CPM have access to the modem Modem ports are password protected to restrict unauthorized access to connected devices Configuration Backup Once you have configured the CPM to fit the requirements of your application parameters and options can be sent to an ASCII text file and saved for future retrieval If configuration is accidentally altered or deleted parameters can be reloaded using your terminal emulation software 1 1 CPM Series Control Port Managers User s Guide Introduction CPM 1600 and CPM 800 This User s Guide discusses both the CPM 1600 and CPM 800 Control Port Managers The CPM 1600 includes 16 ports and the CPM 800 includes eight ports All other features function identically Typographic Conventions Throughout this manual typefaces and characters have been used to denote the following A e g E Indicates a key combination used to invoke a command For example the text A Control A indicates the Ctrl key and the A k
