8. Operation 8.1. Any-to-Any Mode Any-to-Any Mode Ports can be connected to other Any-to-Any, Passive, Buffer, or Modem Mode Ports by accessing command mode and issuing the /C Command. All ports can be configured for the Any-to-Any Mode. 8.1.1. Port Connection and Disconnection The APS provides communication between devices without the requirement that both devices use the same communication parameters. This allows you to connect devices that use dissimilar baud rates, parity, handshake, and etc.
APS-8M Asynchronous Port Switch; User’s Guide To Connect ports, proceed as follows: 1. Access command mode as described in Section 5.1. If the Password Prompt is displayed, enter a password that permits Supervisor Mode. 2. Invoke the /C command to connect the desired ports. a) Resident Connect: To connect your resident port to another port, type /C xx [Enter]. Where xx is the number or name of the port you want to connect.
Operation To disconnect ports, proceed as follows: 1. 2. 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 Resident Disconnect command formats; the One Character Format and the Three Character Format (for more information, please refer to Section 5.5.3.
APS-8M Asynchronous Port Switch; User’s Guide 3. No Activity Timeout: Providing the Timeout Disconnect feature is enabled at either connected port, a No Activity Timeout can disconnect Resident Ports, or Third Party Ports. a) RS232 Ports: To configure the Timeout Disconnect Feature for the RS232 Ports, invoke the /P command to display the Port Configuration Menu for the desired port as described in Section 5.5.3. Option 10 enables and defines the Timeout Disconnect Feature.
Operation 6. Your port will be connected to the first available port in the group. If all ports are presently connected, the APS will respond with a "BUSY" message. 7. It is only necessary to enter enough letters of the port name to differentiate Hunt Group ports from other ports. Type an asterisk (*) to represent the remaining characters in the port name.
APS-8M Asynchronous Port Switch; User’s Guide 8.2. Passive Mode Passive Mode Ports function the same as Any-to-Any Mode Ports, but do not allow access to command mode. A Passive Mode Port can communicate with other ports, but cannot enter command mode, and therefore cannot invoke commands to redefine port parameters, display status, and etc.
Operation 8.3.1. Reading Data from Buffer Mode Ports To retrieve data from Buffer Mode Ports, you must first determine which port buffers contain data. To check port buffers for stored data, access command mode and type /S [Enter] to display the Port Status Screen.
APS-8M Asynchronous Port Switch; User’s Guide 8.3.2. Port Buffers The Status Screen lists the amount of Buffer Memory currently used by each port. The APS uses buffer memory in two different ways, depending on the user-selected port mode. • Any-to-Any, Passive, and Modem Mode Ports: When two ports are communicating at dissimilar baud rates, the buffer memory prevents data overflow at the slower port. • Buffer Mode Ports: Stores data received from connected devices.
Operation Notes: • When a Modem Mode Port exits command mode, or the DCD line is lost while command mode is active, the APS will pulse the DTR line to the modem. The unit will then send the user-defined modem command strings to make certain the modem is properly disconnected and reinitialized. • All APS-8M RS232 ports can use both the unit’s internal modem and external modem(s) installed at another RS232 port, providing that the port password allows access to the desired modem port.

9. Saving and Restoring Configuration Parameters After the APS-8M has been properly configured, parameters can be downloaded and saved as an ASCII text file. Later, if the configuration is accidentally altered, the file with the saved parameters can be uploaded to automatically reconfigure the unit without the need to manually re-assign each parameter. Saved parameters can also be uploaded to other APS-8M units.
APS-8M Asynchronous Port Switch; User’s Guide 9.2. Restoring Saved Parameters This section describes the procedure for using your communications program to send stored parameters to the APS. 1. Start your communications program and access the APS command mode; if the password prompt is displayed, enter a password that permits access to Supervisor Mode. 2. Configure your communications program to upload an ASCII text file. 3. Upload the ASCII text file with the saved APS parameters.
10. Upgrading APS-8M Firmware When new, improved versions of the APS-8M operating firmware become available, the /UF (Upgrade Firmware) function can be used to update the APS-8M unit to the new firmware version. Updates can be uploaded to the unit via SetUp Ports one and two, or via the internal modem port (Port 8). To install a firmware update, proceed as follows: Note: All other ports will be disabled during the firmware upgrade procedure. 1. Obtain the update file.
APS-8M Asynchronous Port Switch; User’s Guide 4. Use your communication program’s (e.g. HyperTerminal’s) upload function to transfer the upgrade firmware to the unit. Select ASCII file format, and then specify the filename and directory location where the firmware upgrade file resides. Note: The Upload function will time-out after one minute of inactivity. If the function times out, type 1 and press [Enter] to continue, or press [Esc] to abort. 5.
11. Command Reference Guide 11.1. Command Conventions The commands described in this section conform to the following conventions: • Slash Character: Most APS commands begin with the Slash Character (/). • Apply Command to All Ports: When the asterisk character is entered as the argument of the /D command (Disconnect Port), or the /E command (Erase Buffer) the command will be applied to all ports. For example, to erase all port buffers, type /E * [Enter].
APS-8M Asynchronous Port Switch; User’s Guide 11.2. Command Response When commands are sent to the APS-8M, the unit can respond with either verbose (English Text) or terse messages (numeric / abbreviated). In the default state, all ports will send verbose command responses. After the unit is installed and configured, the port configuration command (/P) can specify an individual response format for each port.
