EL232 XPCD Operation

Prior to powering up the EL232 XPCD, double check wiring and setup making sure all wiring is properly
terminated. 

Once power is applied, the EL232 XPCD enters the power on clear mode. All status switches are read at this time
and the unit is configured for baud rate, indicator type, and input signal type. The EL232 XPCD display goes
through a power up sequence which can provide valuable information about the operating condition and setup of
the unit. 

4.1

Lamp Test

The first display during power on clear is a lamp test.
This test lights all displays, decimal points, and
annunciators. Proper indication is “

8.8.8.8.8.8.

” with

five illuminated LEDs above the main display.

4.2

Software Revision

The software revision number which is in the EL232
XPCD is displayed. The display shows 

rEV 2.6

 for

normal revision 2.6 program. This helps identify
specially modified software.

4.3

Current Baud Rate Setting

The EL232 XPCD next shows the current baud rate
setting it had read from switch SW1. The display
shows, 

bAUd12

 for 1200 baud, 

bAUd24

 for 2400

baud, 

bAUd48

 for 4800 baud, or 

bAUd96

 for 9600

baud. 

4.4

Input Signal Type

The display shows 

rS232

 for RS232 data setting or 

C LOOP

 for current loop input. Refer to Section 3.1

for further information on setting the correct input
data type.

4.5

Indicator Type

Finally, the EL232 XPCD shows the indicator type
which the EL232 XPCD is receiving. This is
displayed as 

Ind 1

 where the 1 can be an indicator

number from 1 to 12.  Refer to Table 4-1 for a
numerical list of indicator types.

From the power on clear sequence, the current status
of the display and the current setup information can be
verified. This can be done at any time by pressing the
reset switch (see Figure 3-9 on page 17) on the CPU
or by removing AC power from the unit.
