HP 50 g - PC connection series with adapter Series USB and null modem troubleshooting

I have the calculator correctly connected to my laptop via a USB series adapter, which is plugged into a null-modem adapter, which is plugged into the serial cable sold on HP Calc.org specifically for the HP 50 g. I started XModem on the calculator, but Conn4x found nothing. Is the process different from that used for USB and Conn4x connections? The problem could be with the USB Serial Driver. I use the default MicroSoft driver installed to connect? Are there tests I can run to determine if the adapter is broken, or the computer or calculator. Thank you very much in advance for your help!

I already tried the following:

  • The two indicators relevant system are correct for the serial communication
  • Tried to reinstall the driver
  • Google for any relevant information that is extremely rare
  • Tried with two Xmodem Kermit servers running on the calculator, press 'Connect' on Conn4X.

Hi!, Ranothil:

If you have the following cable "null modem" (http://commerce.hpcalc.org/serialcable.php), you can transfer, all

data, HP50G, to the PC and vice versa, throughout the connection Kit (Conn4x), without issue.

Please, see this link, to education, to transfer data with the serial null modem and connectivity kit cable... http://sense.NET/~Egan/SKB/ or... http://www.hpmuseum.org/cgi-sys/CGIwrap/hpmuseum/archv017.cgi?read=125259

Note: best if you transfer data, HP50G, PC and vice versa, through the microUSB.

  • Connect LabVIEW with a via USB pic 18f4550

    Hello everyone, as the title suggests, I would like to have communication with the PHOTO above, in order to to use as a sort of buffer control. Nothing complicated or fancy, I would use it as a sort of buffer, with LV, do all the calculations and lifting heavy objects, while the PEAK only manages communication and nothing else. Specifications are:

    -I would like to order 2 Motors step by step, I already have the drivers who are driving binary pulses (1 pulse = 1 step)

    -May or may not require an analog (0 - 5V) encoder feedback, so for now, let's assume that Yes

    -As mentioned, nothing complicated like PID or advanced control in the PIC, just send and receive some movement, LV will do most of the work as it's the only one I'm more familiar with

    -I am well informed, but not particularly good in programming C (not my cup of tea), but I'm pretty adept at BASIC, my particular environment is PIC Simulator IDE of Oshonsoft and his recent iteration, the Basic compiler.

    I've done a substantial amount of research, but most of the info is pretty obsolete, and most of the download links no longer work. I know I should use General dll of Microchip (already had), but would like to know if someone has done something similar, or could give me a starting point. I also read the white paper found here: http://www.ni.com/tutorial/4478/en/#

    So basically, if anyone has the tracks on a good starting point, tutorials, I have to take or bases miss me, they would be welcome. Thanks to a bouquet.

    I think it would be simpiler using a virtual COM port device such as the ones FTDI

    Then schedule a connection series on your PIC and just use VISA in LabVIEW to communicate with the captain like communicating with any other serial device.

    Ouch! Please do not yell at us. We can hear you if you type normally,

    You have an internal fax/voice modem, but if it is not connected to
    a land line, cannot you send/receive faxes like this.

    Your only choice is to not make use of your machine gun, but to use a web site

  • Can connect to with the bad IP and the subnet RVS4000

    Hello

    I'm relatively new to networking so that post in the forums, please be gentle. I have a strange problem. I tried to update our switch of production over the weekend with a new Gigabit switch. Everything was going well after the change and the network has been a significant change in speed.

    But when I came back Internet was down on Monday. So I tried the switch troubleshooting to see if there was a loop or something like that and put in managed mode so I could watch the config page and enjoy the function STP. When you try to access the config page I entered the default IP address in my browser and a connection appear so I tried to connect and she didn't then I noticed that the title of the tab navigator says RVS4000. So out of curiosity I put the creds for the router and here let me the router.

    The router has a static IP address and use a different subnet, then the default IP to 192.168.2.1 with switch. I put the old switch and removed a new production, but can still get to the router with IP, it is the static address and address 2.1.

    This before everyone knows or knows what I could possibly hurt? The fool is now the switch is made of bricks. I have a new future, but have need solve this problem until I put it into production.

    Thanks for any help, sorry for the novel.

    Hi Chris, it is possible that someone has set up a VLAN on the router. All ip addresses VLANS are IP management for the unit. You can check the L2 switch of the device tab and this is not the case. You can also verify that the vlan 1 router is that you are pregnant.

  • FDM with adapter Essbase: mapped and overall Dimensions

    Hello

    IM implementation of FDM 11.1.2.2 with planning, a tent to undersatnd the adapter. Can someone explain to me the diffeerence between mapped and a global dimension? And in addition the la difference difference between assets, required, use the list, use as looked up?

    I understand not mapped are the dimensions that you'll have in the columns in your flat file and a map. In addition, Im guessing that a dimension world are those that you like POV in your flat file and you need to match the control tables. But I do not understand what are the control tables for?

    In various examples of control arrays are periods and scenarios. However my source system gives me the period in a column, so I really don't need such as a global dimension. What is the impact of periods as overall not having not and so do not have as a control panel?

    Sorry for my questions newbiee and greetings!

    FDM the period targeted (month/year) and the script is used by parameters of your POV. The period and the scenario you choose here determines where he goes in the target, not the contents of your file. Therefore, you may have a file of data to say that November 2012 real but load via FDM with a POV value January 2012 Budget and it is where all the data of the IRA. In your import format you will find therfore defined only associations with the dimensions mapped so that the concerned source values are associated with the correct size mapping table. Control tables control associations for periods and scenarios/categories. In your case the period of the value in column a is not used for any mapping activity.

    You can put validations in FDM scripts to check the contents the queue data correspond to the period / settings of the script in the selected POV but as FDM are mainly a user focused on the process of loading, is normally not necessary.

  • VLAN Trunking ESXi with blade HP c7000 and Juniper EX3200

    Hi, I'm quite new in VMWare field, because recently my company is going to launch a public cloud in Malaysia, his will combine several technologies, so I guess I have no choice but to go and study all materials and related software. My background is system and network, I understood the concept and success raising (EX3200) switch with port is lucky trunking with id vlan native 48, where my other vlan is 45-47. However later on, I will consider how I need to activate multiple markup in ESXi, I found this VST it one that I seek, I created VLANs inside the vSwitch. Then I change my machines in vlan respectively (label to change card). Then I change connect it outside (adapter for vMotion and multi-service, call Management Network default console) to vlan 48, however, when I change, my blade appear to be isolated from others. I remove id vlan, or put as 4095, then it works again, but the machine all connect them my VLAN (45-47) can not ping to the outside, please help me in this...

    Yes do not activate the switch with VLAN, vlan 48 which is native on the trunk port create a portgroup of vmware on the vswitch who has network you cards connected to the switch but leave the tag of vlan empty this will be then in the vlan default of the switch, and then create three more vmware exchanges one for each vlan and this time make sure you enter the id vlan.

    then provide that the routing has been implemented each vm will be able to talk to each other (if there are now firewalls to stop).

  • MacBook does not connect to Philips TV with adapter USB - C

    Recently, I bought USB Apple-C (very expensive) adapter for my Macbook from 2016. When I connect the computer to my Philips TV via an HDMI cable, after some initial flicker, I see a stable picture on the TV. The problem is that the hard stable image usually less than one minute. This flickering cycle and temporarily stable image is repeated several times until I have finally get an error message on the TV that says "video Format not supported" and the screen turns white.

    The HDMI cable that I use works perfectly with a Sony laptop connected to the TV even. Adapter USB - C has been also updated after I bought it.

    Someone has the same problem with their TV?

    Hello

    You are able to test it on another TV, with another HDMI cable?

    If it all works, I might suggest to return the adapter HDMI Apple and get another via online service or your dealer.
