27 sie 2015 · General guidelines says most cables will support 115k baud, using x-on/x-off protocol (stop start is data on tx/rx lines) are limited to 30M, or about 100' with shielded cable. UTP cables using this same protocol setup are limited to about half the speed, so maybe 56k.
29 mar 2001 · Maximum Cable Length. As we have seen, the cable-length specification once included in the RS-232 standard has been replaced by a maximum load-capacitance specification of 2500pF. To determine the total length of cable allowed, one must determine the total line capacitance.
The standard does not define a maximum cable length, but instead defines the maximum capacitance that a compliant drive circuit must tolerate. A widely used rule of thumb indicates that cables more than 15 m (50 ft) long will have too much capacitance, unless special cables are used.
Maximum cable lengths. The maximum working length of a cable varies depending on the characteristics of the transmitters and receivers, the baud rate on the cable, and the capacitance and electrical impedance of the cable. The RS-232 standard states that a compliant port must provide defined signal characteristics for a capacitive load of 2500 pF.
4 mar 2021 · Using typical underwater cables, allowable combinations of cable length and baud rate for Sea-Bird instruments communicating with RS-232 are shown below: Maximum Cable Length (meters) Maximum Baud Rate*
15 maj 2012 · There is no single safe answer. It has a lot to do with the length of the cable, surrounding electrical noise, and how fast you want to go. Ethernet uses CAT5 cable to transmit at 10 Mbit/s for the slowest variety, so 1 Mbit/s is easily doable if you take the proper precautions. Note that with ethernet each signal gets its own twisted pair, and ...
16 mar 2023 · Cable Length: One of the most important considerations when choosing an RS232 cable is the length of the cable. RS232 signals can only travel so far, and the longer the cable, the more likely you are to experience signal degradation or loss.
