Setting the date and time
The date and time are items Q and R on the Change Configuration menu,
respectively.
Setting the correct date and time is critical to proper schedule and system
operation.
The VLX can receive BACnet Time Sync commands from other BACnet
devices. Problems with the date and time are most often attributed to Time Sync
conflicts or errors.
Note We recommend using Time Syncs for setting up the BACnet system to
send the correct date and time to the VLX on a regular basis. Refer to Compass
Help for more information about sending Time Syncs.
The date and time are persistent as long as the coin-cell battery is operational. If
the coin-cell battery is losing its charge, the date or time may become inaccurate.
Final set up and check out at the operator workstation
After you have configured the VLX with HyperTerminal and connected it to
appropriate networks, use a Compass operator workstation to:
• Confirm network communications, if applicable, and add a record to
Device Manager
• Set up inputs for their type, scaling factors, and filter values
• Download DDC
• Set up automation features
• Confirm EXP/AXM communications
If the VLX is on a BACnet internetwork, the operator workstation can connect
using the internetwork.
See Compass Help and documentation for more information and instructions.
