Epson Powerlite 7850p Technical Specifications

							EPSON PowerLite 7850p Projector
10 - EPSON PowerLite 7850p Projector 6/03 Note: If the projector does not respond to the remote control, make 
sure batteries are installed and the switch on its side is turned on. 
The projector also might not respond if the batteries are weak, 
you’re standing at too great a distance from the projector, ambient 
light is too bright, a certain type of fluorescent light is present, a 
strong light source (such as direct sunlight) shines into the infrared 
receiver, or other equipment emitting infrared energy is present 
(such as a radiant room heater).
Using the Control Panel
This table summarizes the functions of the buttons on top of 
the projector. 
Controlling Multiple Projectors
If you’re using more than one projector for your presentation, 
you can use the projector’s ID system to switch between them 
using a single remote control. To do this, you need to set a 
different ID for each projector. During the presentation, it’s 
easy to change the remote control’s ID to match that of the 
projector you want to use. When you want to switch, simply 
change the remote control’s ID to match that of your second 
projector.
Setting the Projector ID
The projector’s default ID is 1. If you need to change it, 
follow these steps:
1. Access the projector’s Advanced2 menu, highlight 
Projector ID and press Enter.
2. Press the right or left side of the  pointer button to 
increase or decrease the ID value. 
3. Press 
Enter to set the value.
4. When done, press 
ESC to exit the menu system.

6/03 EPSON PowerLite 7850p Projector - 11 Setting the Remote Control ID
The remote control’s default ID is zero, which allows it to 
control any projector (although not switch between 
projectors). If you want to switch between projectors, follow 
these steps to change the remote control’s ID to match that of 
the projector:
1. Press the 
ID button on the remote 
control. You see it light up. 
2. Press one of the numbered 
buttons on the remote 
control to select the desired 
ID (0 through 9). Select zero 
to control all projectors, or 
select a number to match the 
ID of the projector(s) you 
want to operate.
The 
ID button’s light shuts off and the new ID is registered. 
If you would like to check the remote control’s current ID, 
press the 
ID button twice in succession. Count the number of 
flashes; this number corresponds to the remote control’s ID. If 
it doesn’t flash, the ID is set to zero.
Presenting Over a Wireless Network
Using EMP NS Connection, you can project images shown 
on your computer screen directly to your audience without 
connecting the projector to your computer. Before you begin, 
make sure you’ve installed EMP NS Connection from the 
CD-ROM that came with your projector. See the User’s Guide 
for installation instructions.
Note: Your computer must be running Microsoft
® Windows XP, 
2000, Me or 98. EMP NS Connection does not support 
Macitnosh.
Starting EasyMP
Before you can connect to the projector wirelessly, you have to 
switch it to EasyMP mode.
1. Turn on the remote control and the projector. Press the 
EasyMP button on the remote control to select EasyMP as 
the source.
2. Locate the EPSON 802.11b card that came with your 
projector. Insert it with the blue label facing outward.Note: Only the EPSON 802.11b card is guaranteed to work. 
Other cards may not be compatible.
Depending on whether your projector is set up to 
connect in Ad Hoc mode or Access Point mode (also called 
infrastructure mode), you see one of these screens:
If you’ve already configured the projector for your wireless 
network, go to “Projecting Wirelessly” on page 15. Otherwise, 
continue with the next section.

Projecting Wirelessly
Once you’ve started EasyMP and set up your projector and 
computer in either Ad Hoc mode or Access Point mode, 
follow these steps to start NS Connection and project 
wirelessly.
Note: You must have installed EMP NS Connection from your 
projector CD-ROM. See the User’s Guide for installation 
instructions.
1. Make sure you’ve inserted the EPSON 802.11b card in the 
projector’s card slot (see page 11). Then select 
EMP NS 
Connection
 from the Windows Start menu.The first time you start NS Connection, you see a dialog 
box asking you to select your network. Select the IP address 
for your computer’s network adapter card and click 
OK.
Note: If you don’t see your network adapter’s IP address, 
allow a minute for it to appear. If your access point uses 
DHCP, sometimes it takes a minute for the server to pick up 
the IP address.
You see the screen below. (If you have previously started 
NS Connection, this is the first screen you see.)
Note: Once you’ve selected the IP address for your network 
adapter, you won’t see the Switch network dialog box when 
you start NS Connection. If you want to change to a different 
network adapter, click 
Extension on the EMP NS 
Connection dialog box, then click 
Switch LAN.
If the connection is working properly, you see your 
projector listed. If you have additional projectors on the 
network, they are also listed, along with their status. The 
color of the status icon next to each projector’s name 
indicates its status:

❏Make sure your wireless signal is strong enough to 
establish a connection (see your computer 
documentation for details).
❏Make sure your computer’s SSID matches the ESSID 
you assigned to the projector (for example, 
CONF 
ROOM). Remember that both the SSID and ESSID are 
case-sensitive. If you’re using channel mode (Ad Hoc 
mode only), make sure the channel set for the 
computer matches that of the projector.
❏If you’re using Access Point mode, make sure the 
projector and your computer are on the same subnet.
❏Restart your computer and start NS Connection again.
❏If you still don’t see your projector and you are using 
Access Point mode, follow the instructions in 
“Connecting in IP Connect Mode” on page 16 to 
connect to the projector manually.
3. Once the name of your projector appears, select it and click 
Connect. If more than one projector is listed, you can 
select additional ones and connect to them at the same 
time. If the selected projector is being used by another 
person, you can still connect to it; doing so automatically 
disconnects the other user.
4. If you are prompted for a keyword, enter the four-digit 
number displayed on the EasyMP Network screen and click 
OK.
5. Once the connection is established, you see your 
computer’s image transmitted to the projection screen, and

Managing Projectors from a Remote 
Computer
The EasyManagement software lets you monitor and control 
projector(s) from a remote computer. These features are 
intended for use by network administrators. 
❏Use EMP Monitor to see your projectors’ status, switch 
image sources, and control basic settings.
❏Use the mail notification function to receive e-mail alerts 
about possible problems.
❏Use a network management utility running SNMP, such as 
HP OpenView,
™ to manage your facility’s equipment from 
a pre-existing system. 
Note: A plug-in is available to allow you to manage your 
projectors in HP OpenView. Additionally, other SNMP 
management utilities may be available in the future. Check with 
your dealer or EPSON for availability.

3. Press the 
Menu button on the remote control and select 
Network from the Advanced2 menu. 
4. If your network assigns addresses automatically, turn on 
DHCP.
If your network does not assign addresses automatically, 
turn off 
DHCP and enter the projector’s IP Address, 
Subnet Mask, Gateway Address, and MAC Address, as 
needed. 
❏To enter numbers using the remote control, press the 
Num button until it lights, then use the numeric 
keypad.❏To change the network addresses from the projector’s 
control panel, press the right and left arrow buttons to 
select the part of the address you want to enter, then
