TABLE 2: PIN DEFINITIONS FOR THE LT2510 TRANSCEIVER
* Pin 18 (GIO_8) on board revisions 0050-00203 Rev 0 and 0050-00196 rev 2 (and below) is internally not connected.
• All I/O is 3.3V TTL.
• All inputs are weakly pulled High via a 20kOhm pull-up resistor and may be left floating during normal operation
• Minimum Connections: VCC, VPA, GND, TXD, & RXD
• Signal direction is with respect to the transceiver
• Unused pins should be left disconnected
