The MVI modules are shipped with adapter cables which convert the RJ-45 connector on the module to a standard DB9 male connector. Related Keywords: RJ45 RJ-45 MVI46 MVI56 MVI71 Read More

No, the 1451-9F adapter has pins 7 and 8 jumpered internally. Read More

Not generally, and most of the time they generate more problems on the network. Our recommendation is to setup your RS-485 network without terminating resistors initially. If communication problems are seen which can be attributed to signal echoes or... Read More

Belden 9841 or 9842 is recommended for RS-485 wiring. Read More

No, generally terminating resistors are not required, and can actually cause communication problems on the network. Every network is different, and has different requirements, but it is best to start without terminating resistors, and add then only... Read More

Yes, you may. Just be sure to use PROFIBUS specific cable (Belden 3079a or equivalent) and proper connectors designed specifically for PROFIBUS DP.  At least two of the connectors (one at each end of the cable) will require PROFIBUS termination... Read More

The Prosoft Modbus device port can be configured for either RS-232, RS-422, or RS-485. RS-232 allows a point-to-point connection, with 50 feet being the maximum length. RS-422 allows a multi-drop connection,with a maximum of 10 devices on the network... Read More

The ProLinx modules are shipped with adapter cables which convert the Mini-DIN connector on the module to a standard DB9 male connector. Read More

Belden 9841 or 9842, or equivalent from another manufacturer, is recommended for RS-485 wiring. Read More

The Prosoft communication module supports 2-wire RS-485 communications. Although not officially supported, it is possible to get at least some 4-wire RS-485 devices to communicate using the following steps. Jumper the receive + and transmit + pins... Read More

The pins in the RJ-45 jacks on the MVI-series modules are numbered 1, 2, 3,...8, top to bottom. Pin 1 is the topmost pin in the jack, pin 8 is the bottommost pin in the jack. You can eliminate the RJ45-to-DM9M adapter cable and wire your... Read More

Oddly enough, yes, it can. That rubber boot is meant to protect the plastic clip on the RJ45 connector from being snagged and broken when the cable is pull though tight spaces. However, it can slide back and forth on the cable, as well. If it... Read More

ProSoft inRAx, ProTalk, and ProLinx solutions do not provide any power via their serial or Ethernet ports. In the case of serial devices, if external adapters or adapter cables are used that expect to get power from the ProSoft solution's serial... Read More
