ENIGMA II DR-81000 Digital Receiver
Version 2.00
3. Installation
Mounting the Receiver
The ENIGMA II DR-81000 receiver is shipped by
default in a standard 3HE 19” desktop housing. With
the mounting holes on the front panel, the housing
can be installed in standard 19” rack cabinets.
NOTE:
the feet of the desktop housing may have to
be removed when installing into rack cabinets.
NOTE:
the LCD screen on the receiver is designed to
be viewed below eye level (12h viewing angle). If the
receiver has to be mounted above eye level, it might
be useful to angle the unit downward improving
visibility or readjust LCD contrast settings.
Printer Connections
Any Printers equipped with a parallel Centronics
interface can be connected to the ENIGMA II DR-
81000 receiver. To connect the printer to the
receivers parallel printer output use a parallel printer
cable.
IMPORTANT:
Using parallel printer cable with only
one common ground wire is not recommended.
Computer Connections
Connect the automation computer to the ENIGMA II
DR-81000 serial COM A port using the supplied
cable, or to USB A using the supplied miniUSB cable.
If the supplied cable is not long enough, a serial Null-
modem cable can be used up to 15 meters in length,
and a longer miniUSB cable can also be used, if
necessary.
The port COM B or the USB B port can be used to
connect to the automation computer, too, in case
they are set to Report mode. The same type of serial
or USB cable can be used on COM B.
IMPORTANT:
Please, do not use standard AT-
modem (straight) cables for the serial ports. Always
use a null modem (crosslink) cable.
Ethernet Connection
The DR-81000 receiver can be connected to the
Ethernet network at its RJ45 modular 10 BaseT
terminal with a standard patch cable. Please, note,
that the connection must be made to a switch or
router on the network. The necessary setup for the
local network can be found in the TCP/IP section.
