Annex 8: Guidelines for Loading METSTAT Datalogger Program into Program

Location 8 of the SM4M/SM192 Storage Module

8-A General

It is advised to permanently store METSTAT datalogger program in program location 8 of the SM4M or SM192 Stor-

age Module. In this case, reloading METSTAT into the CR10X is automatically accomplished by connecting the SM4M/

SM192 to the logger, and toggling the switch on the PS12-LA power supply OFF/ON. METSTAT is then stored in the

logger’s RAM, and made the active datalogger program without any further user intervention.

This annex presents detailed instructions how to store METSTAT into program location 8 of the SM4M or SM192.

8-B Hardware Connection

Figure A8 presents the hardware components required for connecting the SM4M/SM192 to PC.

Figure A8: Hardware Components Involved in Connecting SM4M or SM192 to PC

The SC532A interface converts the specific data structure of the SM4M/SM192 to RS-232 Personal Computer com-

patible format. Since it runs on 110 V, use a 220-110 transformer between mains and the SC532.

Note: Do not keep 220-110V transformer near to the PC/Monitor otherwise the screen will start flickering.

Connect the SC9PS cable to the SC532A and serial port 1 or 2 of the PC. Connect the SM4M/SM192 with the blue

SC12 cable to the SC532A interface. All hardware components are now installed. Make sure power is supplied to the

SC532A.

Communication between SM4M/SM192 and personal computer is enacted through the PC208 Datalogger Support

Software, which icon is presented below:
