D. Rear Panel Connections (Cont'd)

A (BNC) - The input signal to be prescaled is applied to this input.

FLOWMETER Connector - Alternately, the flowmeter output may be prescaled thus producing

engineering unit totals such as Barrels, Gallons or Pounds.

E. Rear Panel Controls

Identical to Section 3.3.1, E except the EXT. T. B./INT. T. B. Switch has no function in this mode.

REMOTE Programming

Purpose

This allows for remotely selecting the functions which are normally selected by the front panel Function

Selector switch, Thumbwheel switches and Multiplier switch. All front panel controls remain as described

herein, and a position is provided (REMOTE) on the Function Selector Switch which transfers the

instrument from front panel control to remote control. A multiple pin connector is mounted on the rear of

the instrument and all connections described below are made through this single connector. Note, that

all other control functions, accessible via the Control connector, J5, remain active.

A. Modes

The front panel Function switch must be placed in the REMOTE position. Five pins in the rear

mounted connector are used to select any one of the front panel functions. A function is selected by

a solid state or contact closure between any one line and circuit Common.

B. Time Base Thumbswitches

Twenty-four pins in the rear mounted connector are used to program the functions normally selected

by the front panel thumbswitches; i.e., four lines for each thumbswitch. Control is in the 1,2,4,8 BCD

format and Logic "1" control bits are applied in the form of solid state switch or contact closures to

the thumbswitch return line (pin 42).
