For example, assume the Monitor Mode is configured as follows: · Switch if Level: 1 - High · Switch to Position: B · Return: On If the circuit starts in position "A", and the monitored line goes high, then the circuit will be switched to the "B" position.
PLS-345 - Physical Layer Switch; User's Guide 5.8. Save Configuration Parameters After the unit has been completely configured, it is recommended to save parameters to an ASCII file as described in Section 8. This allows quick recovery in the event that the unit is reset to default parameters, or if the configuration is accidentally deleted or altered.
6. The Status Screens The PLS Status Screens are used to display current conditions of the three switched A/B circuits and the network interface. There are two status screens; the Circuit Status Screen (/S), and the Network Status Screen (/SN). 6.1. The Circuit Status Screen The Circuit Status Screen lists the current A/B settings for the PLS-345's three switched circuits, and also summarizes userselected parameters, such as Command Echo, Inactivity Timeout, and Command Confirmation.

7. Operation The PLS-345 offers three different methods for switching A/B paths: 1. Manual A/B Switching: The manual A/B Switches on the PLS front panel are used to initiate switching of one or more A/B Circuits. 2. Code Activated A/B Switching: ASCII commands are sent to the PLS to initiate switching of one or more A/B Circuits. 3.
PLS-345 - Physical Layer Switch; User's Guide 7.2. Code Activated A/B Switching The PLS offers three different commands for controlling A/B switching: · The /A command, which is used to switch one or more circuits to the "A" line. · The /B command, which is used to switch one or more circuits to the "B" line. · The /D command, which is used to switch all three circuits to their user-defined default A/B positions. All three of these commands are available in both System Mode and User Mode. 7.2.1.
Section 7: Operation The Command Confirmation Prompt: Normally, when the /A or /B commands are invoked, the PLS will prompt you for confirmation before actually implementing the command. If you wish to suppress this confirmation prompt, and execute commands without confirmation, you can employ one of the following methods: · Include the ",y" option in the command line (e.g. /A 1,y.) · Disable Command Confirmation as described in Section 5.4. · Enable the Automated Mode as described in Section 5.4. 7.2.2.
PLS-345 - Physical Layer Switch; User's Guide 7.3. The Monitor Mode The Monitor Mode allows the PLS-345 perform automatic A/B switching in response to signal level changes at the monitor port on the instrument back panel. The Monitor Mode can be set to monitor a Contact or an RS-232 Line. For more information on the Monitor Mode, please refer to Section 5.7.
8. Saving and Restoring Configuration Parameters After the PLS 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 assign each parameter. Saved parameters can also be uploaded to other PLS units. This allows rapid set-up when several units will be configured with the same parameters.
PLS-345 - Physical Layer Switch; User's Guide 4. The PLS will send a series of ASCII command lines which specify the currently selected PLS parameters. The last line of the file should end with a “/G-00” command. When the download is complete, press [Enter] to return to the "PLS>" command prompt. 8.2. Restoring Saved Parameters This section describes the procedure for using your terminal emulation program to send stored parameters to the PLS. 1.
9. Application Examples 9.1. Monitoring Signal Drop and/or Power Loss In this application, the PLS-345 will monitor the DTR signal from a data device. If the signal drops or the data device loses power for more than one minute, the unit will automatically switch circuits 2 and 3 to the "B" line. Figure 9.1: Monitoring Signal Drop 1. Connect Line from Data Device: Connect a line from the Data Device to the Monitor Input Connector as shown in Figure 9.1. 2.
PLS-345 - Physical Layer Switch; User's Guide Figure 9.2: AUX Port Connection 3. Configure Monitor Mode: Access the PLS command mode as described in Section 5.2. At the PLS> command prompt, type /M [Enter] to display the Monitor Mode Parameters Menu. Note that the Monitor Mode Parameters Menu is not available in User Mode. Set Monitor Mode Parameters as follows: a) Item 1 - Monitor Mode: On. Note: Do not enable the Monitor Mode until you have finished defining the other Monitor Mode parameters.
Section 9: Application Examples Figure 9.3: Monitoring a Switch or Relay 9.2. Monitoring a Contact In this application, the PLS will monitor a switch or contact. When the contact closes (signal goes low) for more than one minute, the PLS will automatically switch module 1 to the "B" position. Later, if the contact returns to the open position, the PLS will return circuit 1 to the "A" position. Note: This example could also be used to monitor a contact or switch that is normally closed.
PLS-345 - Physical Layer Switch; User's Guide Figure 9.4: AUX Port Connection 3. Configure Monitor Mode: Access the PLS command mode as described in Section 5.2. At the PLS> command prompt, type /M [Enter] to display the Monitor Mode Parameters Menu. Note that the Monitor Mode Parameters Menu is not available in User Mode. Set Monitor Mode Parameters as follows: a) Item 1 - Monitor Mode: On. Note: Do not enable the Monitor Mode until you have finished defining the other Monitor Mode parameters.
10. Command Summary All PLS-345 commands conform to the following standards: · All commands normally begin with the "/" (foreword slash) character. If you wish to temporarily suppress command echo, use the "\" (backward slash) character instead of a forward slash. · All command lines are invoked by pressing the [Enter] key. · Both the System Level Password and User Level Password are case sensitive. 10.1.
