similar to: RS485 Audio device

Hello, Does an R package exist for communication with instruments using GPIB (IEEE 488) protocol? Something similar exists in python for control of instruments over GPIB, RS232, or USB buses (http://pyvisa.sourceforge.net/) Thanks, Marko

Hi All, I'd like to modify an existing driver to support my Victron Multiplus inverter/charger. This device is not supported by the victron driver. I do have serial protocol definition from Victron - which is a big bonus... Could anyone tell me which of the existing drivers will be easiest to modify? Thanks Thanks -- Boli

Hi, I am trying to make a program in C to communicate with a temperature sensor over my serial port that uses RS-485 and is a half duplex. I am however having trouble getting the device into RS-485 mode, is it possible to use RS-485 mode in Centos 6.5 or does it only support RS-232 mode?

I installed R-2.9.0 yesterday, and followed the instructions in the R for Windows FAQ, 2.8 What's the best way to upgrade? It reads "run update.packages(checkBuilt=TRUE, ask=FALSE) in the new R and then delete anything left of the old installation." I did this but it returned an error. It's the checkBuilt=TRUE which causes it, though I don't know why: leaving it out or

Hi all, Is there a method in centos where a program can be started that listens on a given IP port and when something connects it will transfer data from the RS232 port to the IP port. reads and writes of course. Trying not to reinvent the wheel if I dont have to... Thanks, Jerry

I just merged drm (Direct Rendering) from HEAD. - Support for latest Intel chips - Support and fixes for many AMD/ATI chips r500 and below - Support AMD/ATI IGP based chips (rs690/rs485) - Lots of code cleanups - Lots of other fixes and changes since the existing drm is 2+ years old If you are experiencing a "garbled" screen with

a friend gave me an old apc smart-ups 1250 it has a rs232 interface but i have no pc with a rs232 port i attempted to use a rs232 to usb adapter but the ups goes nuts i connected the ups to batteries and verified it was working properly when i plug the usb cable into the pc the ups shuts down when i attempt to turn it on it beeps twice and shuts down this all occurs before i start the nut software

I am running asterisk 13.1.0 In pjsip.conf, the endpoint section has an aors and an auth field. I can name the auth field anything I want. The key is to set the auth=field accordingly. However, when I try this with the aors field, it never works. It seems I have to name the aors=field to match the name of the endpoint section. Is this correct? Would there ever be a need for multiple aors to

Hi, Yes, we're implementing the dialplan in realtime too. Here the contents of sorcery.conf: [res_pjsip] endpoint=realtime,ps_endpoints aor=realtime,ps_aors contact=realtime,ps_contacts [res_pjsip_endpoint_identifier_ip] identify=realtime,ps_endpoint_id_ips Cheers, Francisco.

Hi all, (sending this again from the correct address) I'm running Asterisk 13.8.0 (I need to check if that happens with 13.9.1 too when I have the time to build it) with PJSIP realtime config. I've defined several aors in the table ps_aors, like this (real url replaced by myurl): *CLI> pjsip show aor pbx-node-1 Aor: <Aor..............................................>

Hello, I am slightly confused by the difference between chan_sip and pjsip. Especially the new (to me) objects aor and contact. I am having trouble mapping them to the typical SIP configuration settings on a phone. Suppose I have a phone with two line buttons, for two extension numbers. Now, I think that means two 'endpoints' in pjsip right? But what exactly is the difference between

Hi All, First off, I've just started using compiz and its fantastic... I'm using compiz with KDE (on FC6), all is OK apart from one small niggle which is when I use the scale or switcher plugins it includes my kicker windows (the desktop panels) in the list, which isn't so pretty. I don't know much about gconf, but poking around in the settings for compiz and found that these

What would be the proper steps to upgrade to 2.6.11 on centos 4.0 This is what I think... tar -zxvf linux-2.6.11.6.bz2 cd linux-2.6.11.6 make oldconfig - enter for all choies presented vi .config - change 8250_NR_UARTS to 36 to support 4 - 8 port rs232 cards make bzImage

I just realized that you are asking about dynamic AORs, not static Contacts in an AOR. That may be the difference. I have never actually tried giving a dynamic AOR a different name. And you wouldn't want more than one dynamic AOR, you'd just use an AOR that allowed more than 1 contact. On Wed, Apr 1, 2015 at 2:59 PM Trey Hilyard <kctrey at gmail.com> wrote: > I don't know

I installed Board Master a software that control a CNC machine to produce PCB (Printed Circuit Board). The software install flawlessly but to check if it works I need RS232 working to control CNC machine. I tried to set connection parameters in Board Master choosing COM1 (the only available) but CNC machine don't move and software keep asking for switching machine on. Of course software and

Greetings ! My goal is to get Twilio trunking working, and with TLS/SRTP. I see this concerning message in my log: [Feb 7 16:50:26] ERROR[20596] res_sorcery_config.c: Could not create an object of type 'endpoint' with id ?twilio' from configuration file ?pjsip.conf? Thus, ?pjsip show endpoints? does not show the endpoint for the Twilio trunk. Hoping for a sanity check of
