INTRAC-305 SPECIFICATION & OPTIONS

firmware change and required the EPROM on the interface

card to be changed.

Mount Type Two types of antenna mount may be used with the INTRAC.

An Az/El mount or a Polar mount. The appropriate one is

selected in “Fitted Options” as AZ/El or Hr-Ang/Declination.

Resolver Type The INTRAC-305 is intended for use with standard Andrew

resolvers, either x2 or x1 versions. Normally the INTRAC-305

is to replace an Andrew APC300 and the antenna will have

been fitted with x2 resolvers. Refer to the earlier specification

section. This is a user configuration option.

Stow Option There is provision in the INTRAC-305 configuration for Az/El

preliminary and final stow positions to be set.

The “Stow” command causes the antenna to be driven to the

preliminary position in both axes. Once at this position the

antenna is driven to the final position.

The “Unstow” command causes the pin(s) to be removed

(where appropriate) and the antenna driven to the preliminary

position.

The preliminary and/or final positions can be set to “not-

used” for one or both axes.

Dual Redundant PSU The INTRAC-305 can be supplied with dual redundant power

supplies. In this option the single PSU is replaced by two

indepenent PSUs and associated combining hardware.

Independent switched power inlets are provided and the

front panel power switch is replaced by status LEDs. The

INTRAC-305 will operate normally when either or both PSUs

are operational. This option must be requiested at time of

initial order
