MD485 RS-485 Multidrop Interface

Current dataloggers and wiring panels (not mentioned in Table 2) provide

12 V on pin 8. For older products not listed, check for 12 V between

CS I/O connector pin 8 and pin 2 (GND) or contact Campbell Scientific.

b. Use default settings of MD485.

Step 3 – Connect Base MD485 to Remote MD485

a. Connect the CABLE2TP cable from the 3-pin terminal block on the Base

MD485 to the 3-pin terminal block on the Remote MD485 as described in

Section 3.3.

Step 4 – PC400/LoggerNet/PC208W Set-up

a. The next step is to run PC400/LoggerNet/PC208W and configure it to

connect to the datalogger via the MD485 point-to-point network you have

set up. The MD485 in a point-to-point network can operate transparent to

PC400/LoggerNet/PC208W. Using the EZSetup Wizard in PC400 or

LoggerNet, transparent communications is set up as if it is a direct

connect. If not using the EZSetup Wizard, simply add a datalogger to a

COM port in the Device Map.
