Wyse's Windows CE-based terminal does it all
Wyse Technology's Winterm 3315SE is the first Windows CE-based terminal I've
tested that supports the Citrix Independent Computing Architecture (ICA)
protocol and the Microsoft Remote Desktop Protocol (RDP). Support for both
protocols means you can deploy the Winterm 3315SE in any thin-client scenario: You can deploy the Winterm 3315SE with Windows NT Server 4.0, Terminal
Server Edition or with Citrix WinFrame or MetaFrame. Furthermore, you can deploy
the Winterm 3315SE in a LAN or WAN environment.
Plug It In
The base unit is a toaster-size device that you can set on a desktop or
mount on a wall using the provided hardware bracket. The unit I tested came with
a keyboard and a mouse. SVGA monitors are available through Wyse.
All the connectors for the Winterm 3315SE are on the back of the device.
In addition to connectors for the monitor, keyboard, and mouse, the
Winterm 3315SE houses a DC power supply connection, a 10Mbps unshielded twisted
pair (UTP) Ethernet port, two serial ports, a parallel port, audio I/O jacks,
and a PC Card slot. You can connect a modem to the serial port for dial-up
connections using ICA or RDP, and you can attach a local printer to the parallel
port.
Some features tie into your choice of protocols. You can use the
audio output port only if you are using the ICA protocol. RDP doesn't support
sound. Similarly, support for the Start key is available with only the RDP
protocol. If you use ICA, you can use the mouse to point and click
Start.
Solving a Mystery
Although Windows-based terminals are nearly universal, the
configuration and operation of each device varies among manufacturers. For the
Winterm 3315SE, the magic keys are Alt+End. This key sequence brings up the
built-in configuration program that lets you define and launch your host
connections.
You can use the Winterm 3315SE configuration program to define multiple
host connections. Each host connection can use a different protocol and network
connection. For example, you can configure one LAN-based ICA connection, one
LAN-based RDP connection, one modem-based ICA connection, and one modem-based
RDP connection. More practically, you can configure connections to different
hosts using the same protocol. You can also configure the Winterm 3315SE to
automatically launch a connection when you turn it on--this useful feature
keeps end users away from the configuration program.
After you define multiple host connections you can press Alt+End to return
to the configuration program and switch between different host connections. This
feature is useful in an environment in which different host servers provide
different applications. For example, if you have an Office 97 application
host, a line-of-business application host, and a financial application host, you
can move from one host to the next using Alt+End. Each connection remains active
until you log off or disconnect it.
Almost Perfect
I found two problems with the Winterm 3315SE. One is the location of the
power switch. The power switch is located on top of the Winterm 3315SE--the
switch spans the breadth of the device and is located near the front of the
unit. The large switch is as easy to turn off as it is to turn on. Many times, I
reached out to reposition the Winterm 3315SE on my desk only to turn it off
inadvertently. The second problem I found is less serious. I was testing the
Winterm 3315SE in my small office/home office (SOHO) lab and connecting back to
a host system running Terminal Server and MetaFrame in the Windows NT
Magazine Lab. My ISDN connection had intermittent problems in which the line
would frequently drop and I'd lose my connection to the host. The problem is
that when the link went down and then back up, the Winterm 3315SE would see the
disconnection but wouldn't let me reconnect to that host unless I turned the
device off and on.
I found the Winterm 3315SE to be the most flexible, easy-to-configure, and
easy-to-use Windows-based terminal I've tested. The Winterm 3315SE's support for
multiple-host connections and the ability to switch between connections is a
compelling feature in any multiple-host environment. I also liked the Winterm
3315SE's support for ICA and RDP--although if you are in a single-protocol
environment, this feature might not impress you
