Troubleshooting
I’ve connected a new Smart Receiver to my computer for configuration but I can’t communicate
with it
• If you are using a Windows computer, clear the ARP cache. From the command prompt and with administrator
authorization, enter:
ARP –D IPADDRESS (e.g., ARP –D 192.168.1.104).
I’ve already programmed a Smart Receiver but can’t find the IP address
• Download the SpyGlass app from http://gofrontrow.com/guides-resources and follow the instructions in the PDF of the
downloaded archive. Spyglass is a Java-based utility designed for discovering FrontRow network devices such as the
Smart Receiver, which exist on your network.
The sound from the Blu-ray player, AppleTV and teacher’s computer cuts out for a few seconds
intermittently
• In a room with ambient noise the teacher’s microphone may pick that up, inadvertently invoking the PrioriTeach (automat-
ic ducking) feature. You can turn this feature off using the Teacher Edition software or from the Smart Receiver’s System
Settings web page
I’ve connected the serial cable from the Smart Receiver to the projector and I’ve verified that
baud rate and other settings are correct, but I still can’t control the projector.
• Try switching the TX and RX wires. In a 9-pin connector the standard is to use pins 2 and 3 for TX and RX, but there is no
standard as to which is which. Most manufacturers use pin 2 for TX and pin 3 for RX, but over 10% use the reverse.
I’ve forgotten my password and need to reset the device.
• Resetting your Smart Receiver involves the same procedure as that for many FrontRow devices: briefly shorting the
RX and TX terminals.
1. Create a shorting connector by inserting the ends of a piece of wire into a Phoenix connector where the RX and TX will
be when plugged in to the serial control port, and tighten the screws.
2. With the device powered down, insert the shorting connector into the serial control port.
3. Power up your Smart Receiver.
4. After 3 seconds remove the shorting connector.
5. If the you still find that the password has not been reset, repeat the procedure with slightly more time or slightly
less time.
