The information presented here is necessary only if you wish to write your own driver, or to connect the ADC-16 to the PC in some unusual way (for example, via a radio modem).

The ADC-16 uses the following RS-232 data lines (pin connections as on ADC-16)

Pin

Name

Usage

3

TX

Data from the PC to the ADC-16

2

RX

Data from the ADC-16 to the PC

7

RTS

Held at a positive voltage (> 7 V) to power the ADC-16

5

GND

0 V line

4

DTR

Held at a negative voltage (< -7 V) to power the ADC-16

 

The driver powers up the ADC-16 by enabling RTS  and disabling DTR to provide the correct polarity power supply.  If these are set incorrectly no damage will occur to either PC or ADC-16.
