5. Setup

Follow these steps to properly set up your Fowler-Sylvac 4 Channel Multiplexer:

1. Placement: Position the multiplexer on a clean, stable, and dry surface. Ensure adequate ventilation around the unit.
2. Power Connection: Connect the appropriate power adapter to the multiplexer's power input port. Plug the adapter into a suitable power outlet.
3. Connecting Sylvac Instruments: Connect your Sylvac Opto RS-232 gages (e.g., Microcal, Ultra-Cal III, Ultra-Digit IV, Ultra-Digit V, Scales) to the input ports on the multiplexer. The multiplexer typically has clearly labeled input ports for each channel.
4. Connecting to D100S or Display Unit: Connect the output port of the multiplexer to the input port of your Fowler-Sylvac 54-618-151 D100S, 54-618-232 Deluxe Remote Digital Display Unit, or 132 Display Unit using the appropriate RS-232 cable.
5. Stacking Multiple Multiplexers (Optional): If connecting more than four instruments, up to four multiplexers can be stacked. Connect the output of one multiplexer to the input of the next, and the final multiplexer's output to the D100S or display unit. Refer to the D100S manual for specific instructions on configuring multiple multiplexers.

6. Operation

Once the multiplexer is set up and connected to your instruments and display unit, operation is straightforward:

1. Power On: Ensure all connected devices, including the multiplexer and the D100S/display unit, are powered on.
2. Instrument Recognition: The D100S or display unit should automatically detect the connected instruments through the multiplexer. Refer to the D100S or display unit's manual for specific instructions on selecting and reading data from individual channels.
3. Data Acquisition: Use the D100S or display unit's interface to select the desired channel and acquire measurements from the connected Sylvac gage. The multiplexer acts as a transparent conduit for data transmission.
4. Channel Switching: The D100S or display unit will manage the switching between the connected channels on the multiplexer.

7. Maintenance

Proper maintenance ensures the longevity and reliable performance of your multiplexer.

• Cleaning: Regularly wipe the exterior of the device with a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the ports or openings. Do not use abrasive cleaners or solvents.
• Storage: When not in use for extended periods, store the multiplexer in a dry, dust-free environment within the specified storage temperature range (-20°C to +60°C).
• Cable Inspection: Periodically inspect all connecting cables for signs of wear, damage, or loose connections. Replace damaged cables immediately.
