The ASCII driver permits the ProLinx module to interface any ASCII device to the

many protocols and networks available. ASCII devices include barcode

scanners, weigh scales, many field instruments, printers, and terminals. The

driver supports one to four ports that provide accessibility from one to four

independent serial networks.

Transmit buffer size: 255 bytes

Transmit characters with pacing: 0 to 65535 millisecond delay between

each transmitted character

Transmit database location: -1=disable transmitter, 0 to 3896

2 Functionality

In This Chapter

Data Flow ................................................................................................9

This section describes the functionality of the ASCII driver.

2.1 Data Flow

The following illustration shows receive and transmit dataflow of the ASCII driver.

Data received from the ASCII device is accepted by the receive driver and placed

in the receive database location configured by the user. The receive driver waits

until the user-configured termination condition is recognized while receiving the

data before placing the new data into the database.

For example, if the carriage-return character (ASCII 13) is used as the

termination condition for a received message, this signals the end of the

message. When the receive driver observes this character in the input stream, it

takes all received characters and places them in the internal database.

In both receive and transmit operations, a signal is required to determine when

new data is received or must be transmitted. The first word in the two data area

is used for this purpose. When the value of the first word changes, new data is

available. Lets look at a receive example. The sequence number in the receive

data block has a value of 0 as set when the module initializes. The ASCII device

sends a new data packet and the termination condition is present. The receive

driver copies the data into the internal data area, sets the message length in the

data area, and finally, sets the new sequence number. Receive and transmit data

block structure is discussed in the following topics.

2.1.1 Receive Data

Data received by the receive driver is placed in the module's internal database in

a fixed format at the location selected by the user. The receiver driver is disabled

if the database start location is set to a value of -1. The following table shows the

structure of the received data.

Word Offset Description

0 Receive sequence number. This register is incremented by the Module's Receive

Driver for each new packet received.

1 Number of characters transmitted (0 to 255) from last transmit request.

2 Number of characters (0 to 256) in receive block (3 to 130).

3 to 130 Received data on port.

The first word of the data block is used to signal when new receive data is

available. Word 1 of the block contains the number of bytes in the last message

transmitted on the port. Word 2 contains the number of bytes in the received

message data area. Words 3 to 130 contain the data received. If the module is

configured to swap the data bytes received, the receive driver will swap the bytes

in each word received before placing the data into the data block. Because the

data received may contain an odd number of bytes, the length of the message

received will be incremented by 1 when an odd number of bytes are received and

the swap option is utilized. This is to avoid losing the last byte of data in the

message.

2.1.2 Transmit Data

Data to transmit by the transmit driver is placed in the module's internal database

in a fixed format at the location selected by the user. The transmit driver is

disabled if the database start location is set to a value of -1. The following table

shows the structure of transmit data.

Word Offset Description

0 Transmit sequence number. This number is incremented by the user's application

for each new packet to transmit.

1 Number of characters received (0 to 256) from last receive request.

2 Inter-character delay for this message (milliseconds between characters)

3 Number of characters to transmit on Port (0 to 255)

4 to 131 Data to transmit on port

The first word of the data block is used to signal when new transmit data is

available. Word 1 of the block may optionally contain the number of characters

processed in the last receive message. Word 2 of the message is used to pace

the characters during the transmission process. This may be required when

interfacing with slow ASCII devices (that is, modems in command mode).
