PRINT OPTIONS

The various Print Options are used mainly in conjunction with a printer and

the Print Request Terminal. They provide a choice of Gemini 3300 data

values to be printed when either the Print Request Terminal is activated or the

“Transmit per Print Options” (P) command is sent to the Gemini 3300. The

various Print Options available are:

1. Print Total Counter Value

2. Print Batch Counter Value

3. Print Process Counter Value

4. Print Display P, B, & T

5. Print Display T, Presets 1 & 2, Batch Preset, and Scale Factor

6. Print Display B, Presets 1 & 2, Batch Preset, and Scale Factor

7. Print Display P, Presets 1 & 2, Batch Preset, and Scale Factor

8. Print Display P, B, & T, Presets 1 & 2, Batch Preset, and Scale Factor

A typical printout is shown below. The Print Options are selected by

setting S4, S5 and S6 on the Serial DIP Switch. See Page 23 for the various

switch settings.

CURRENT LOOP INSTALLATION

WIRING CONNECTIONS

It is recommended that shielded (screened) cable be used for serial

communications. This unit meets the EMC specifications using Alpha #2404

cable or equivalent. There are higher grades of shielded cable, such as, four

conductor twisted pair, that offer an even higher degree of noise immunity.

When wiring the 20 mA current loop, remove the 7-position terminal block

(TBD), located on the right side of the top board. Refer to the numbers listed

with the terminal descriptions below or on the top label, and install each wire

in its proper location on the terminal block. When all connections are made,

replace the terminal block into its proper location.

TERMINAL DESCRIPTIONS FOR TERMINAL BLOCK TBD

1. -20 mA SRC(COMMON) - Common for 20 mA SRC & Print Request

terminal

2. PRINT REQUEST - The Print Request Terminal is connected to common

to request the Gemini 3300 to transmit according to the Print Options mode

that has been selected. (Minimum Activation time = 25 msec.)

3. +20 mA SRC - The 20 mA SRC terminal provides the source current for

one of the loops.

4. SO- (Serial Out-)

5. SO+ (Serial Out+)

The Gemini 3300 transmits the requested data on these terminals (SO- &

SO+). They are connected in series to the receive input of the device to be

connected.

6. SI- (Serial In-)

7. SI+ (Serial In+)

The Gemini 3300 receives commands on these terminals (SI- & SI+). They

are connected in series with the transmit or output terminals of the device

to be connected.
