CRT CONSOLE POSITION EQUIPMENT

February 1996

Part No. 004-3039-273

3.13.15 TDV-OP453 PIC AUDIO CHANNEL 3

AND 4

The basic TDM-PIC or TDV-OP450 supports two

(2) speaker ports only. TDV-OP453 is a hardware

option which specifies an applique board for the PIC

card which must be ordered for any PIC supporting

three (3) or four (4) speaker ports.

The TDM-PIC assigned to each console position

will support only

Selected Audio and Unselected

Audio speakers. TDV-OP453 allows the use of two

(2) TDV-OP451 speakers or TDV-OP452 dedicated

channel speakers in addition to or in lieu of the

Selected and Unselected Audio speakers.

3.13.16 TDV-OP454 PIC ON-LINE PERSONALI-

TY REPROGRAMMING

The console personality programming is normally

resident in one or sometimes two EPROM chips on the

TDM-PIC. Any change in the console programming

requires that a new personality EPROM be pro-

grammed and installed on the PIC. Replacement

EPROMs can be obtained from the E.F. Johnson fac-

tory or, with proper equipment and software, pro-

grammed in the field by a qualified technician. The

console must be taken off-line for EPROM replace-

ment - a process which generally can be completed in

less than 60 seconds.

TDV-OP454 is a hardware option which elimi-

nates the need for EPROM replacement by providing

personality resident in E

PROM which can be repro-

grammed with the console on-line using an IBM or

compatible PC with E.F. Johnson menu-driven soft-

ware. A console equipped with TDM-OP454 can also

be reprogrammed by modem from a remote location

by a qualified technician or by the E.F. Johnson fac-

tory if the Central Processor is equipped with TDM-

OP209 REMOTE DIAGNOSTICS AND PROGRAM-

MING. This option is furnished as standard equipment

on all consoles sold after September 1, 1993.

3.13.17 TDV-OP460 CONSOLE EQUIPPED FOR

REMOTE OPERATION

TDV-OP460 is a software option which permits

the Dispatch Position console to be placed at virtually

unlimited distances from the Central Processor Pack-

age using dedicated telephone lines or microwave mux

channels. Typically, five (5) telephone pairs (type

3002 unconditioned lines) or three (3) full duplex

microwave channels are needed for full console opera-

tion. Extra monitor or dedicated channel speakers

may require additional link pairs or mux channels.

TDV-OP460 operates at 9600 baud using a spe-

cial algorithm which provides control response times

virtually indistinguishable from those of a console

operating via a direct wire line link.

NOTE: Option specifies programming only

. Order

TDM-RIA and channel modules separately for each

console as required.

3.13.18 TDV-OP462 EQUIP CONSOLE FOR EFJ

MULTI-NET II

TDV-OP462 is a software option which equips

the console to access and control Multi-Net II talk-

groups. One (1) TDV-OP462 is required for each con-

sole that will be connected to a single or multiple RNT

Multi-Net system. The option includes a replacement

overlay for the Radio Control Panel which features the

E.F. Johnson Multi-Net II logo instead of Orbacom

TDM-150 logo.

TDV-OP462 requires that the Central Processor

Package be equipped with option TDM-OP262 and

TDM-EFJ cards for each Dispatch Position/RNT in

the system. It should be noted that each Dispatch

Position has a limit of 128 equivalent control modules

or talkgroups. A typical Multi-Net system will require

five (5) module equivalents for the talkgroup over-

head; Individual Call In, Individual Call Out, Unmoni-

tored Group Emergency, Unmodulated Group Assign-

able and Telephone Interconnect. Conventional

channels, paging keys, auxiliary switch keys and tele-

phone screens all use some number of module equiva-

lents. Contact the factory for applications assistance

in determining the talkgroup capacity for each spe-

cific systems.

NOTE: Options TDM-EFJ, TDM-OP262, TDM-

OP362 are available only through E.F. Johnson and

may not be ordered directly from Orbacom.
