Section 7 - Serial Data Interface
The RD 1000’s two serial ports are used to communicate with external devices.
The Laser Port is a dedicated interface to an LTI laser, and the Data Port is a
dedicated interface to an external data collector. The accessories needed for
downloading measurement data are available from LTI or an Authorized LTI
Distributor.
The serial data interface uses RS232 voltage levels and transfers information in
an ASCII, hexadecimal format. Figure #11 shows the pin-out assignments for the
RD 1000’s two serial port connectors.
