SBIG Ethernet to Parallel Adapter Operating Manual
Thank you for buying SBIG’s Ethernet to Parallel Adapter (E2P or EPA). This accessory
allows you to talk to your Parallel Port based SBIG Camera (ST-7, ST-8, etc.) over an
Ethernet network. This makes it easy to talk to a camera in your backyard observatory from
the comfort of your house. While the Parallel Ports of most computers can be extended to 50
feet and possibly further, Ethernet cables on networks can be hundreds of feet in length. The
E2P adapter works with SBIG’s drivers and applications based upon those drivers running on
Microsoft Windows, Macintosh OSX and Linux.
What’s Included
SBIG’s Ethernet to Parallel Adapter consists of the following items:
Ethernet to Parallel Adapter Box
US 12VDC @ 400ma Wall Transformer
Serial Cable for Setup
Ethernet Patch Cable
Floppy Diskette with Setup Utilities
CCDOPS Version 5 Camera Control Software
Users in areas without 110V power will need to substitute an appropriate wall transformer or
power source. The power requirements for the Ethernet to Parallel Adapter Box are 9 to 34
Volts DC at 2 Watts ( 225ma @ 9V, etc). Simply unscrew the Wall Transformer from the
power connector on the back of the unit and attach the alternate power source, noting the
proper polarity:

When you first receive the Ethernet to Parallel Adapter box you must install the software and
the unit must be setup to your particular network configuration. This section details what is
required to start using the accessory.
Installing the Windows Software
If installing on a Windows 2000 or XP machine make sure you are logged in as the
administrator first. Run the SETUP.EXE program on the first floppy diskette. Follow the
instructions presented in the install program. This will install the CCDOPS Version 5
software, drivers and utility programs. After the installer program has finished Windows
NT/2000 users should do the following to start the driver:
Run the INSTDRV.EXE program from the install directory (typically
C:\Program Files\SBIG\CCDOPS5)
Enter SBIGUDRV in the Driver Name field.
Click on the Uninstall button followed by the Install button.
Running with Mac OSX or Linux based Software
Follow the separate instructions for installing the SBIG Drivers and application software for
your Mac OSX or Linux based systems.
Powering up the Unit
The typical installation of the Ethernet to Parallel Adapter (EPA) will involve connecting the
accessory to a free port on a hub on your Ethernet network as shown in the diagram below.
Please note the following regarding this accessory:
The Ethernet patch cable provided with the unit is meant to connect the EPA to a
hub. If you want to connect the EPA directly to an Ethernet adapter in your
computer without going through a hub you’ll need to obtain a “crossover” cable
and use that to connect between the computer and the EPA.
The SBIG Ethernet to Parallel Adapter is a 10 Base-T appliance but will work
fine on Auto-sense Ports of 100 Base-T hubs.
Ethernet Hub
Power up the unit by plugging in the power supply and connect the EPA to the network with
the Ethernet Patch Cable. The PWR LED on the front panel should illuminate indicating

power to the unit and the LNK LED should illuminate indicating the connection to the live
Ethernet network. If the LNK LED is not illuminated it’s probably because you have
connected directly to your computers Ethernet Adapter and did not use a crossover cable.
Also the ACT LED may blink with Ethernet activity.
Ethernet Configuration
As the Ethernet to Parallel Adapter is an Ethernet Appliance it may need to be configured for
operation on your network. From the factory the Ethernet to Parallel Appliance is configured
as IP address Changing the IP address is done using a serial cable and terminal
program like the Windows Hyper Terminal application. Before we start that though you’ll
need to obtain the following IP address information:
IP Address of the EPA – This is the IP address you will assign to the EPA (the factory
configured address is It needs to be an IP address on your local network that
is unassigned to any other devices. Typical installations include:
I access the Internet using a dial-up modem or I don’t have a local network - In this
case you need to assign an IP address to both your PC and the EPA. A typical setup
would be to set your PC to and the EPA to
I access the Internet using a Cable Modem or DSL Modem – In this case you either
have a local network and need to assign an IP address for the EPA that is compatible
with your network or you need to contact you Internet Service Provider (ISP) and ask
them for which address you can use. You must pick a fixed IP address for the EPA
even if your computers IP address is assigned dynamically by your ISP.
Network Mask – This is typically for small in-home networks. For larger
installations check with your Network Administrator.
Gateway Address – If you have a gateway on your local network that allows access to the
internet you will need its IP address. If not just leave it blank.
For convenience write the values you have chosen in the spaces below:
PC IP Address:
EPA IP Address:
Network Mask:
Gateway Address:
____ . ____ . ____ . ____
____ . ____ . ____ . ____
____ . ____ . ____ . ____
____ . ____ . ____ . ____
If you need to assign an IP address to your PC (actually the TCP/IP Protocol of your Ethernet
Adapter) use the Network Control panel as shown below:

Now let’s use the Hyper Terminal application to configure the Ethernet to Parallel Adapter:
1. Double-click to open the “Direct to COM 1” setup file in the E2PUTILS
sub-directory of the install directory or run the Hyper Terminal application from
your Start Menu -> Programs -> Accessories -> Communications and configure
Hyper Terminal for COM 1, 9600 Baud, 1 Stop Bit, No parity and Hardware or
None Flow Control.
2. Connect the provided serial cable between your PCs COM 1 port and the Ethernet
to Parallel Adapters Console port.
3. Hit the Reset button on the EPA and you will see text start to scroll across the
Hyper Terminal screen. While the text is still scrolling hit the Space Bar on your
PC. This stops the EPA from running the Server Program and allows configuring
the unit. If you don’t see a “B:>” prompt1 as the last line on the screen hit the
reset button again then hit the Space Bar.
4. At the “B:>” prompt type CONFIG then hit enter. The CONFIG program will
ask you for the IP address, subnet-mask and gateway address as we discussed
above. Enter the values you determined above. The CONFIG program may also
ask for the Primary and Secondary Name Server addresses. You can simply hit
the enter key there. If you make a data entry error you can rerun the CONFIG
Does the “B:>” prompt from the EPA remind you of MS-DOS? It should because the EPA is actually a micro
version of a PC computer running an embedded version of DOS.

5. At this point the EPA needs to be rebooted by hitting the Reset switch on its front
panel. You can quit Hyper Terminal and put the diskette away. If you ever move
the Ethernet to Parallel Adapter to a different Network or change your Network
configuration you will need to reconfigure the unit as described in this section.
At this point you can connect the camera to the EPA using your parallel cable that came with
the camera and power-up the camera.
Using the Ethernet to Parallel Adapter with CCDOPS
Run CCDOPS from the install directory and use the Graphics/Comm Setup item in the Misc
menu. Select Ethernet in the Interface pop-up item then fill in the EPA’s IP address in the
Ethernet Address field. Hit OK then use the Establish Com Link item in the Camera menu.
In a few seconds the CCDOPS software should establish a link to the camera as shown in the
Link field in the lower-right corner of the CCDOPS main window. That’s all there is to it.
You can now use CCDOPS just as if your camera were connected to the parallel port.
If you are not able to establish a link try the following trouble-shooting guide:
Make sure you are using CCDOPS Version 5 or later (with the Gold Icon, not the
Black Icon) or that the third party software you are using supports the Ethernet to
Parallel Adapter.
Make sure that the Ethernet to Parallel Adapter is plugged in and that the PWR LED
is illuminated.
Make sure that the EPA is plugged into the network, the hub is powered up and the
LNK LED on the EPA is illuminated.
Make sure the camera is connected to the EPA and is powered up. If necessary try
connecting the camera to the PCs parallel port and establishing a link there to make
sure it is working correctly. Don’t forget to use the Graphics/Comm Setup command
to reconfigure CCDOPS for the LPT port and then back to the Ethernet port.
Check the settings you have used for the EPAs IP address, sub-net mask and Gateway
address. When the unit is powered up and connected to the network you should be
able to ping the EPA using the DOS ping program. When pinging the unit the ACT
LED on the EPA should momentarily illuminate.
