RANEXP Master Port Expander,

RANBROAD Expander

The

RANEXP

is a Master Port Expander that is used in place of a

RANCPU

Control

System Master Card when the total capacitance of the

RANGER

system's control cable

run exceeds the

RANCPU

's limit (+60,000 pF). Each

RANEXP

accommodates 11 runs of

cable with a maximum of 60,000 pF. It requires 12

VDC

at 200 mA and is mounted in a

single rack space (1.75"). The

RANEXP

will not be manufactured after 1996; its

replacement is the functionally equivalent

RANBROAD

(see the following section).

The

RANEXP

(or

RANBROAD

) is typically connected directly to the

RANPCSW

computer for

programming purposes by the

2302

232 cable (supplied with the

RANPCSW

Parts Required

12 Four-pin Phoenix connector (supplied with the

RANEXP

)

1 Two-pin Phoenix connector (supplied with the

RANEXP

)

4 Mounting screws and washers (supplied with the

RANEXP

1 One-pair shielded cable for connecting

AMX

Control Link West Penn D291 or

equivalent)

1 18-gage power wires (black and red)

1 Serial interface cable (supplied with the

RANPCSW

or refer to drawing

Estimating the Number of

RANEXP

RANBROAD

Ports

In order for the

RANGER

system to operate correctly with your

RANEXP

RANBROAD

, it is imperative that you not exceed the distances specified for the

cable that you are using (as detailed in the following table).

Locate the type of cable you are using in Table 4.
