Can 2 hand held Paradigm touchscreens be connected at the same time?

Yes. You Can have multiple handheld portable touchscreens on the system at once, 18 in fact per processor. I assume you mean the portable handheld version via an Ethernet cable?  A tech will have to add the touchscreen into your system configuration.

Chris - Referring to the P-TS7-H.  Now that I know that this is an option, I'll get a quote on the touchscreen.  Thanks, Tom

With the P-TS7-H you must have at least one P-LCD-DOCK or WAS (Wireless Access Station) per P-TS7-H you want to use at the same time. A single DOCK or WAS is unable to have two P-TS7-H units connected through it at the same time.

Since you already have "4 locations" where the handheld can connect, presumably that means you already have 4 DOCKs and/or WAS, which is great!. If you purchase a second P-TS7-H then you'll be able to have both units connected in two separate locations concurrently.
