For address 23 on a System Enhancement Module (SEM), the DIP switch setting requires Switch 2 and 3 to be ON, with all other switches OFF.
Understanding SEM DIP Switch Settings
DIP (Dual In-line Package) switches are small manual electrical switches commonly found on circuit boards, used to configure the behavior of a device. In the context of a System Enhancement Module (SEM), these switches are crucial for assigning a unique address to the module, allowing it to communicate correctly within an alarm or automation system. Each specific address corresponds to a unique combination of ON/OFF positions for the DIP switches.
Exact DIP Setting for SEM Address 23
To configure a SEM for address 23, you must precisely set its DIP switches as follows:
- Switch 2: ON
- Switch 3: ON
- All other switches (e.g., Switch 1, Switch 4, etc.): OFF
This particular combination ensures the SEM is correctly recognized as address 23 by the connected system, facilitating proper system integration and functionality.
Comprehensive SEM Address DIP Settings
For a broader understanding, here's a table outlining the DIP switch settings for various common SEM addresses, including address 23:
| Keypad Address | DIP Switch Setting | VISTA Programming Command |
|---|---|---|
| 20 | Switch 3 and 4 ON, others OFF | *193 |
| 21 | Switch 2 ON, others OFF | *194 |
| 22 | Switch 2 and 4 ON, others OFF | *195 |
| 23 | Switch 2 and 3 ON, others OFF | *196 |
Practical Tips for Setting DIP Switches
Properly setting DIP switches is essential for the correct operation of your SEM. Consider these practical tips to avoid common configuration errors:
- Use a Small, Non-Conductive Tool: To avoid damaging the switches or the circuit board, use a jeweler's screwdriver, a pen tip, or a specialized DIP switch tool. Avoid using your fingers.
- Verify Each Switch Position: After setting, visually inspect each switch to ensure it is firmly and completely in its intended ON or OFF position. A partially set switch can lead to unreliable operation.
- Understand "ON" Indicators: Most DIP switches have clear markings for the "ON" position (e.g., text, an arrow, or a raised side). Confirm you understand these indicators for your specific module before making adjustments.
- Power Cycle the System: After changing DIP switch settings, it is often necessary to power cycle the SEM and, in some cases, the main control panel. This allows the system to recognize and apply the new configuration.
- Document Your Settings: For systems with multiple modules or complex setups, maintaining a record of each module's DIP switch settings can be invaluable for troubleshooting, maintenance, or future upgrades.
By carefully following these guidelines, you can ensure your SEM is correctly configured for its assigned address, enabling seamless operation within your security or automation system.
