Installation 2-1 PRISM 4001
2. Installation
This chapter contains information and instructions required
to prepare the TxPORT PRISM 4001 unit for use. Included
are initial inspection procedures, mounting instructions,
configuration guidelines, connection instructions, and pow-
ering information.
Safety Summary
This manual contains information and warnings which must
be followed by the user to ensure safe operation and to
maintain the equipment in safe condition.
This WARNING sign denotes a poten-
tial hazard to the operator. It calls
attention to a procedure or practice which, if
not correctly performed or adhered to, could
result in injury or loss of life. Do not proceed
beyond a warning sign until the indicated
conditions are fully understood and met.
Follow proper ESD (electrostatic dis-
charge) procedures when handling
circuit boards.
Supplied Materials
The 4001 is shipped from the factory with the 1051-to-DDS
adapter (PN 9-1001-075-1) and reference manual. The user
may also require the following additional materials for
installation and operation:
• -48 VDC power source
• Network and DTE Interface cables
• 20-gauge stranded wire (or similar) for DC power and alarm
connections
For specific applications, the users may require additional
cables and adapters. The interface requirements of any
application may be met using the appropriate cable. Contact
TxPORT if assistance is required in cable. Additional cables
are also shown in Optional Equipment Part Numbers on
page 1-4.
Mounting
The PRISM 4001 is a modular unit that plugs into a 1051
chassis.
Chassis Assembly
Up to 12 PRISM 4001 units may be inserted into a chassis
and the chassis may be installed into a 19-inch or 23-inch
rack using four screws. Connections are made from the rear
of the chassis (refer to Figure 2-6 and Figure 2-7 on page
2-7).
Unit Configuration
The PRISM 4001 can be hardware configured by switches
or software configured by using a terminal connection to the
front panel supervisory (SUPV) access port. The terminal
interface provides more capabilities than do the configura-
tion switches.
If there is a power failure and the configuration has been
saved, the 4001 retains its configuration in non-volatile
memory. This feature allows the unit to automatically
restore normal service at power loss. See sections Configu-
ration on page 4-1 and Store Parameters to EEPROM on
page 4-13 for more information.
The 4001 stores its operating firmware in Flash memory. If
a software upgrade is ever needed, TxPORT will provide
the hex files, the download program, and the downloading
instructions.
Hardware switches on the side of the circuit boards will
configure most simple applications. These switches are
described in the following paragraphs. If an ambiguous con-
figuration is programmed, the unit overrides invalid config-
uration items.
The unit is hardware configured using four DIP switches
and two slide switches, which are located along the upper
side of the unit (see Figure 2-2). Switch positions are num-
bered as follows: position 2 of Switch S4 is referred to as
Switch S4-2, and so on.
Before installation, verify each configuration switch setting.
A removable configuration guide is included at the back of
this manual to record option selections for future reference.
Configuration Switch S1
Switch S1 (Figure 2-1) is used to set the configuration
parameters listed in the following paragraphs.
Factory default settings are underlined through-
out this manual.
