Which Mode Should I Use During The GPIB-RS232 Communication?

Issue Details

I want to establish a connection between my computer and the GPIB device through USB-RS232 and GPIB-RS232. At this time, I could not control my GPIB device through the host computer.

Solution

In the process of using the host computer to control the GPIB device, it is necessary to pay attention to whether the host computer is connected to the GPIB port or the RS232 port. According to the manual, the D mode is selected by default. At this time, the interface of the host computer will select GPIB. If the interface of your host computer is to select the COM serial port, you cannot use D mode.

1. Open GPIB-Serial Converter Wizard.
2. Select Interface and click Nest.
3. Select change configuration and click Next.
4. Select C mode Click Next.
5. Configure serial settings and GPIB Settings and click Next.
6. Click Update in the Confirm Setting.

Additional Information

• D mode： When the GPIB-RS232/485/422 is configured to operate in D mode, you can connect a serial device to a GPIB system with a GPIB Controller responsible for addressing the GPIB-RS232/485/422 to talk or listen. 
• S mode：When the GPIB-RS232/485/422 is configured to operate in S mode, it lets your serial device act as a Controller in the GPIB system, addressing one or more devices, and performing other GPIB Controller functions. 
• G mode：When the GPIB-RS232/485/422 is configured to operate in G Mode, it is used as a GPIB device sending and receiving data to and from the serial device, while a GPIB controller manages the system. GPIB-RS232/485/422 implements two GPIB devices on the same physical GPIB interface. The first address is the GPIB-RS232/485/422 address. The second address is the serial device address. Data a GPIB controller sends while the GPIB-RS232/485/422 is addressed is interpreted as programming messages. Data a GPIB controller sends while a serial device is addressed is sent over the serial interface. 
• C mode: When the GPIB-RS232/485/422 is configured for C Mode, it acts as a passthrough device that reads serial data and transfers it over GPIB.
