Northeast Innovations Hint #13 - Advanced Topic: Universal Station LCD Fields

Description:

This document describes how to change the way the fields of numbers display on the LCD of the Model 3008 Universal Station. It contains a quick explanation followed by a more detailed explanation.

Materials Needed:

• Northeast Innovations Universal Station Model 3008

Quick LCD Fields Explanation

1. There are 16 available characters on the bottom row of the LCD.
2. You can have up to four different fields on the bottom row of the LCD. (A field is a group of characters.)
3. Each of the first 4 digits of the A93 memory location represents a field. (The last 4 digits do other things and are zeroes by default.)
4. In memory location A93, the digit for each field denotes the position of the last character in that field. Each digit is a hexadecimal number.
5. To turn a field off, put in a zero in A93 for that field. Use leading zeroes when fewer than four fields are used.
6. You cannot turn off the fourth LCD field. If you put in a zero for the last field the station will make the 16th character the last one used in the row.

Detailed LCD Fields Explanation

Description of the LCD:

The alphanumeric display (also called the LCD) of the Model 3008 Universal Station has two rows of 16 characters for a total of 32 characters. The top row of the LCD is normally used by the station to indicate its status. The lower row of the LCD is generally used to indicate the ID number of the transcriptionist and/or the ID number of the record the transcriptionist is working on.

The following table shows the layout of the LCD characters:

Lower LCD Row Options:

The lower row of the LCD can be programmed to display up to four different fields separated by spaces. Here are a few examples of what could be displayed on the bottom line of the LCD:

• a 4-digit physician code, a space, and a 5-digit patient ID (10 characters are used including the space)
• a 3-digit department code, a space, a 4 digit physician code, another space, and a 6-digit patient ID (15 characters are used including the spaces)
• a 2-digit hospital code, a 2-digit department code, a 4-digit physician code, and a 5-digit patient ID (all 16 characters are used including the spaces)

How to Program the LCD Display Options:

The key to programming the way the LCD displays numbers lies in the A93 memory location. (If you would like information about how to program a Universal Station memory location, please refer to Hint #5 - Universal Station Programming Reference.)

More specifically, the first four digits of the A93 memory location control the fields of the LCD display. (The last four digits of the A93 memory location control other features of the station.) The default setting for A93 is 306D0000. The purpose of each of the first four characters (by default these are 306D) is described in the following table:

Which character of A93	Default Value	Purpose
First	3	Last position of the first LCD field. The value 3 means that 3 digits will be displayed as the first LCD field. After the third digit, there will be a space.
Second	0	Last position of the second LCD field. The value 0 means that the second field is disabled and there is no 2nd field used in this configuration.
Third	6	Last position of the third LCD field. The value 6 means that the third field ends with the 6th display position. After the 6th position, there will be a space.
Fourth	D	Last position of the fourth and final LCD field. The value "D" is a hex digit equivalent to the number "13" (See the table below). Therefore, the last digit displayed on the LCD will be the 13th digit in the row.

The Universal Station uses hex digits in its memory locations. This allows numbers between 10 and 15 to be represented with a single character. The following table shows the hex equivalents to digital (normal) numbers.
Regular Number	Equivalent Hex Digit	Station Keypad Button
0	0	0
1	1	1
2	2	2
3	3	3
4	4	4
5	5	5
6	6	6
7	7	7
8	8	8
9	9	9
10	A	A
11	B	B
12	C	C
13	D	D
14	E	*
15	F	#

Examples:

This section will take each of the examples mentioned above and show how to program each one.

Example 1:

First, let's look at the default setting of A93 which is 306D0000.

This setting means that the first field has three characters. Then there is a space. The second field is set to zero and thereby disabled. The third field is set to "6" meaning that the field ends with the 6th digit. The fourth field is set to "D", which means that it is set to "13". So, the last digit displayed is the 13th.

So, the 2nd line of the LCD display will appear as follows:
