Pin Descriptions
The following table describes the function of each of the connector pins. In the following
descriptions, a CMOS logic low or logic 0 is < 0.8V and a CMOS logic high or logic 1 is
> 4.0V.
Pin Name Pin # I/O Pin Description
PWR 1 and 2 I
+5VDC ± 0.15V power input. 50mV peak-to-peak ripple. The
current requirement is 720mA max. The connector is rated at
0.5 A, hence the use of two pins for power.
GND 3 and 8 N/A Ground
TXD 4 O Serial data transmit output. This is a CMOS output.
RXD 5 I Serial data receive input. This is a CMOS input.
