Should an error occur in the checksum, the Error LED (RED) will flash momentarily indicating a
failed packet.
2.7 Current Monitor (J8)
2.8 TX Range Test Configuration Jumper (J5)
The current monitor allows for the developer to monitor the current that ONLY the TRXXXX device is
using. By removing the jumper installed at J8 (see Figure 7) and connecting an ammeter across the two
pins, the current usage of the TRXXXX device may be monitored. Connecting the ammeter must be
performed BEFORE powering the board.
By placing the shorting jumper on J5 (see Figure 8) the board is configured for a Range Test transmitter at
power-up. Before moving the switch SW1 to “ON” the jumper must be installed. After installation, move
the switch to the “ON” position. The four LED’s will sequence and the “heartbeat” LED will flash as well as
the TX packet and serial traffic indicators (see section 2.4). Each time a packet is sent the TX indicator
will flash. The TX indicator LED will flash rapidly indicating Range Test packet transmission. Refer to
Figure 9.
