Rs232 Analog Module

Does anyone here have an rs232 analog module? any idea how to set it up?

The instructions in the manual look really good. I see there's example macros in macro.mac Any trouble after doing all this?

Text from manual:

RS232 Analog Input/Output Modules


CamSoft's RS232 Analog input/output solutions currently consist of two options: CamSoft ND Series solutions and our CSA Series solutions. Both are robust options for various analog input/output applications. Both series of analog solutions use the standard RS-232 communications port on the computer to read or send out up to 10 volts.


CamSoft's ND Series Analog Solutions

The RS-232 analog input/output modules use the standard RS-232 communications port on the computer to read or send out ±10 vdc voltage.

To accomplish this, the RS232 signal is first converted to RS-485. Refer to Part No. ND-6520 (RS-232 to RS-485) Converter:

Before connecting the analog modules to the RS-485 network, each module must be reconfigured to have a unique ID address. By default every new module has the same address (01). Hence, if you are only using one analog module, it is ready to use. However, if you have more than one, you must setup each module to the ND-6520 (Converter) individually and run that module's configuration command to set the address. You can use the Analog Module Administration Utility or your CamSoft software to set these.

The ND-6520 device is the heart of the RS-485 chain of modules. It sends the digital data across the chain to each module. This device does not need to be configured for anything other than factory default.

Step (1)
Connect the 9-pin serial cable between this device and the computer's COMM Port.

Step (2)
You must supply power to the ND-6520 and all other analog devices.
Note: If you only have one analog module, the mini AC/DC adapter power supply is adequate. However, if you have more than one analog module, then use Part No. NDP-243

Step (3)
Refer to the analog module documentation for all wiring and configuration for the RS-485 chain.

For an RS-485 to communicate between all modules, only two (2) terminals are needed on the converter -- the (Y)DATA+ and (G)DATA- terminals. The TX+, TX-, RX+, RX- terminal connections are not used in an RS-485 network. Rather, these are for an RS-422 network.

Step (4)
Insert or customize the logic required for analog input or output.

Use the COMMFILE.FIL file to trap and check for any return codes and incoming data. The COMMFILE.FIL file is event driven and whenever an analog module sends data to the COMM Port, this file will automatically execute any logic in the file.
