A200Sensor to PC Interface

Expand AllCollapse All

1. Is it necessary to purchase the A200 with a CS650 or a CS655?

   While not necessarily required, anA200 Sensor to PC Interfaceis useful for connecting a computer directly to the CS650 or CS655 for diagnosis, changing the SDI-12 address, uploading new firmware, and verifying sensor functionality. Typically, only one A200 needs to be purchased unless multiple users with multiple computers need to perform these tasks.

2. Can the A200 be used to monitor the input and output of pressure and temperature transducers through a computer?

   No. The A200 is only used to configure the CS451 and CS456 pressure transducers.

3. Can more than 10 CS650 or CS655 sensors be put on the same data logger terminal?

   Yes. Because there are a total of 62 available SDI-12 addresses (0 to 9, a to z, A to Z), it would be possible to communicate on the same universal terminal or control port with 62 sensors if each one had a unique address.

   In the specifications for the CS650 and the CS655, a limit is stated of 10 sensors per universal terminal or control port because the -VS option gives the sensor an SDI-12 address that matches the last digit of its serial number. That limits the available addresses to 0 to 9, for a total of 10 available addresses. To use addresses a to z or A to Z, change the sensor address with anA200 Sensor to PC Interfacec或终端ommands as described in the “SDI-12 Sensor Support” appendix of theCS650/CS655 manual.
