The default is not screen. And the often used analog input signals have mA,mA,V and V. We also provide special manufacturing for other special analog input signal. It supports standard Modbus protocol,simple and easy to use. The converter is single way isolated. The isolated converter adopts independent DC power supply.
Power supply-input-output is also isolated. Standard 35mm DIN-rail mounted. Please install tightly and stably. Recommend vertical installing. I trust this helps, Mlv. As an example, I once worked with an analytical balance that accepted commands and returned data over an RS line. I think you sent it a letter 'T' to make it tare, and it would acknowledge with something like 'ok' when it had done so. Then you would send it a letter 'M' to make it measure, and it would respond with a printable ASCII string including the measurement and the units.
I think there was a mode where you could command it to transmit continuously, so it would send measurements as fast as it could make them, and you could watch it settle. A friend who insisted he was not actually a programmer built a nice graphical front end for calibrating precision pumps, all built in HyperCard stacks and running on a Mac. Some of the two machines' commands collided, but luckily not the ones he needed.
If your balance is anything like ours was, you need bidirectional communication, and I don't think On the other hand, it's not rocket science.
If you have time, you could probably make your own black box using nothing smarter than a Basic Stamp. If it is an AB plc, I know that the AB website has standard code to bring RS through your serial port on the front of the processor.
If your using that same port to get online then that would not be a good way. Your balance probably has an RS output because it is a precision instrument. Using mA to deliver measurements adds two error sources, the mA transmitter, and the mA receiver. This may destroy the precision of your balance.

Output isolation from signal and power grounds eliminates potential ground loops. Dual solid state relays for control or alarm, isolated. Rated mA at Vac or Vdc. The relays can respond to digital readings or to received control characters, or be commanded via the Modbus protocol or Custom ASCII protocol.
This software can be downloaded from this website at no charge. Programmable Streaming Input Modes Six data conversion modes are user selectable to receive and process streaming data. Remote A processes single values with a digital address. An alarm character is optional. Remote S processes single values without a digital address. Remote 1 processes the 1st of up to 4 readings embedded in a Laureate transmission. Remote 2 processes the 2nd of up to 4 readings embedded in a Laureate transmission.
Remote 3 processes the 3rd of up to 4 readings embedded in a Laureate transmission. Remote 4 processes the 4th of up to 4 readings embedded in a Laureate transmission. Specify the start character at the beginning of the string, the number of characters following the start chracter to be ignored, the number of characters to be processed following the lastignored character, and the stop character at the end of the string.
