Are terminating resistors required on my RS-485 network?
Viewed 1 times since Tue, Nov 28, 2006
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
Are terminating resistors necessary on my RS-485 network?
Viewed 1 times since Tue, Nov 28, 2006
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
May I make my own PROFIBUS cables?
Viewed 1 times since Tue, Nov 28, 2006
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

How can I connect my 4 wire RS-485 device to my ProSoft communication device?
Viewed 1 times since Tue, Nov 28, 2006
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
What are the pin outs for the RJ-45 jack on my Prosoft MVI module?
Viewed 1 times since Tue, Nov 28, 2006
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
Can the rubber boot on the RJ45 end of the ProSoft RJ45 to DB9M adapter cable cause communication disruption?
Viewed 1 times since Fri, Feb 8, 2008
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
I have a device that expects power to be provided through a serial or Ethernet connection. Do ProSoft communciations solutions provide such power?
Viewed 1 times since Mon, Feb 18, 2008
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
