inavy: weapon control interface; module, weapon control interface (wci) (drawing name)
isusceptiable to electromagnetic interference damage; IEEE-488 interface the wci shall contain two 8-bit parallel maintenance bus interfaces that conform to IEEE-488.1, ieee standard digital interface for programmable instrumentation; these interfaces shall be capable of functioning as talkers, listeners, or controllers; each interface shall support a data transfer of at least 250 kilobytes per second; each interface shall be capable of driving 20 feet of cable; one of the two IEEE-488 interfaces shall support the system functionality (communication with external equipment) , while the other interface shall support the testing of the first interface; rpc interface the wci shall interface to one or two rpcs
the wci is part of the phalanx high order language (hol) computer system; wci provides the external interfaces between the hol computer and the phalanx weapon control group (wcg) and between the hol computer and an external maintenance device on an IEEE-488 bus

Identification Item Identification Guide (IIG) and Item Name Code (INC)
Definition Definition of approved item name (AIN): "INTERFACE UNIT,AUTOMATIC DATA PR"
A self-contained item which permits the transfer of information between various types of computer support equipment and computers which would not otherwise be compatible. Excludes modem, communication; expander card, computer, automatic data processing; circuit card assembly; and cable assembly (as modified).
7025-01-492-6192 Material Hazmat, Precious Metals, Criticality, Enviroment, and ESD
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
Represents items with both esd and emi sensitivity.
Represents items with no adp components
The item is a non-aviation critical safety item (csi) whose failure will result in serious damage to equipment or serious injury or death to personnel.
Identification Codes
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
Material Management Material categorization and source of supply
Navicp-erp 700 robbins avenue philadelphia, pa 19111-5099
Material Codes
SOS: Source of Supply. A three position code or routing identifier code (ric), which identifies the source of supply activity.
SMIC: Special Material Indicator Code. A two position code, which categorizes material on the basis of requirements for source or quality control, technical design or configuration control, procurement, stocking and issue control, special receipt, inspection, testing, storage, or handling.
MMAC: Material Management Aggregation Code. A two position code that identifies an item of supply to be managed by a specific activity manager.
MCC: Material Echelon Code. A two position code employed by the marine corps in classifying items into categories by materiel category and procurement echelon. the alphanumeric management code is in the first position and identifies the materiel category
IMC: Denotes wether items shall be subjected to integrated management under the defense supply agency or retained by the individual military service or other department of defense components for their management. Assigned by th activity responsible for item management coding.
