PSC-2 2220 connected to the same Bus RS232, using turns
I want to do using two PSC-2220 experience which, in turn, use the same RS232 cable (I intend to fill the cable). I manage the turns with shared variables. Is this possible? I mean, is that of the interface RS232 can be shared if a CFP2220 does not use it?
Hi ggarza. RS - 232 is not designed for more than two devices to communicate. It might be possible with enough
diodes and prudent to programming, but I expect it would be a challenge.
A better approach would be to use RS - 485, which is designed to support more than two devices.
Ago RS485 to RS232 converters available which will allow you to connect your device; controllers of-2220
already have a RS-485 port.

Is it possible to have two mice connected at the same time?
Hello. I have a gamer mouse, and I am pretty tired of changing the battery every now and then. So I was wondering if I could connect a wired mouse, I could use on the desktop, while my current mouse is always connected - for when I want to do some gaming. Windows Vista will allow that I have two mice connected at the same time?
Hello
You can connect two mice of universal Bus controller to the computer, but it goes to show that a single pointer.

Hi, I recently "lost" my MacBook Pro because of water damage. Fortunately, I've been using time Machine\Capsule and I have a MacBook Pro that is connected to the same network/device. I need to restore a few files in the backup TM of the computer 'lost' on computer 'work '. I was able to 'Browse' the other TM backup (click the icon TM plus the button 'Alt'). The Web browsing is extremely slow (took about an hour to break down / find the file on the network). However, I tried to copy the file and I get errors of the alias. Please advise me on what I am doing wrong.
Thank you

NAT9914 - direct connection to the GPIB bus
Hello
I have some experience with NAT9914xx. I understand, from various sources, this ASIC is connected to the GPIB bus through a Transceiver ICs, i.e. it SN75ALS160 and SN75ALS162. While I'm waiting for the part, I wish I can perform some tests.
So here's the question: If the only devices exist on a GPIB bus is my test Board and a GPIB equipment, can I have the NAT9914 on my board test connected directly to the GPIB bus without using the transceivers?
Thanks & best regards,
Tan of WH
Hello
These transceivers are absolutely necessary to communicate with GPIB instruments. It's why they're in the hardware section of the manual 9914. Transceivers will display correct tension/line transitions. Without them, there will be errors in communication.
I hope this helps.

5520 HP usb and a wireless connection at the same time
I have set up my new 5520 HP with USB connected to my desktop (Vista) for maximum reliability and can print via printer share from my laptop (XP), but I'm obviously missing out on HP web services. Can I have the USB connection or wireless connection at the same time?
Hello f1charlie,
Its new r: YES, because it would be 2 printer icons. One for the USB and the other for the wireless.
The icon of the printer wireless would be similar to Hp 5520 (network).
You can set these printer (USB or network) icon to by default.
But again, every time that you want to print using any application. Click file > print, which will display a dialog box, where, in, you can select the printer icon.
Kind regards

Two internet connection on the same PC (WiFi and ethernet)
I have windows 8. I have two internet connections. A cable (wired) and another in the microwave (wifi). Normally isn't a problem because desktop computers are on the cable connections and the TV, laptops and other toys are on wifi.
But sometimes I want to use two connections on a PC, like download a large file and stream and watch the Broncos game at the same time. I want to use Ethernet as a main and did use WiFi when Ethernet is too busy. I can't understand how to do this. Anyone know?Hi Gerard,.
You can activate the Wifi and cable connected at the same time, but you can use the Internet from one of them. The computer will prefer the cable if the cable is connected.
If both are capable of providing Internet access, computer will prefer the wired (Ethernet) network to access the Internet (and not use the Wifi network to access the Internet).
The advantage of using two connections is to get Internet access without interruption when a connection does not work.
I hope this helps! Let us know if you have other problems with Windows in the future.

Desktop sharing, allow two users to connect on the same desktop
Does anyone know if view Horizon be configured in such a way that:
-Two (or more) users can connect on the same desktop
-vSGA can still be used
The reason why I ask, is that in my area there is a request for collaboration in which two people on different locations want to go through a 3D medical treatment plan and discuss on the phone. Documentation of the Horizon does not say that it can, but it does not say that he can't.
There is nothing on the Horizon that would in native mode. You must use a product type to have two people viewing the same third party screen sharing office.

How user by VM (XP) can connect at the same time?
Hello guys,.
We test VMware View 4 and so far work fine, but I have a question? How many user by VM can connect at the same time? I test with 2 VM (XP) in the pool, but I want to use more than 2 users, but when I try to login doesn't say "no resources available", what that means is that a single user by VM? Us who is running Terminal Server and try to find alternatives.
Thank you
It's the same as with a XP machine. 1 single user can connect at the same time.

PREVENT CONNECTION WITH THE SAME CREDENTIALS
I developed an application. I gave 5 business users access, but more users are using it in connection with the same user name and password. I use custom authetication based on apex.
Is it possible to prevent two simultaneous connection with the same credentials.
Thank you
UmeshA suggestion, it is NOT perfect...
You must use custom authentication... In this configuration, you add a column to the table with user names, call it online and use a car1. When the user connects and you check their authentication, if it passes, you update the table with a 'Y' in the line with their ID card.
When they log out, you're going to run a process to update at the same table, replacing the 'Y' by "n" or null...
So when a user connects, you will also verify their line use an if the column is set to 'Y', then your custom authentication MUST return the error that this connection is already recorded...
Thank you
