What is a dh485/rs-232c interface module?
About the DH485/RS-232C Module The DH485/RS-232C interface module, catalog number 1747-KE, is a communication interface module that acts as a bridge between DH485 networks and devices requiring DF1 protocol. The DF1 port on the interface module can be configured for RS-232/423, RS-422, or RS-485 devices.
What is Rs 232 & how does it work?
This essentially means that RS-232 defines the function of the different signals used in the interface. These signals are divided into four different categories: common, data, control, and timing. See Table 2. The standard provides abundant control signals and supports a primary and secondary communications channel.
What is RS-232 connector size?
The third area covered by RS-232 is the mechanical interface. Specifically, RS-232 specifies a 25-pin connector as the minimum connector size that can accommodate all the signals defined in the functional portion of the standard. The pin assignment for this connector is shown in Figure 2.
What is RS-232 data carrier detection?
**This signal is more commonly referred to as Data Carrier Detect (DCD). The third area covered by RS-232 is the mechanical interface. Specifically, RS-232 specifies a 25-pin connector as the minimum connector size that can accommodate all the signals defined in the functional portion of the standard.
