INSTRUCTION MANUAL

Table 4-10. Communication Module
Purpose: This module is used to configure the Datalink port parameters (e.g., baud rate, parity selection,
etc.).
Title
Symbol Datapoint Default Attribute
Instrument
Address
IA B01 0
It identifies the address of this instrument on the
Datalink network. Each unit connected to the Datalink
network must have its own unique address. Valid
addresses are from 0 -31.
Baud Rate BR B02 253
This datapoint value designates the baud rate (data
transfer rate) of the Datalink network. The baud rate
must be the same for all of the instruments connected to
the same Datalink network. Datapoint values and their
corresponding baud rates are as follows:
Value Baud Rate Value Baud Rate
255 28800 9 28800
254 14400 8 14400
N/A N/A 7
19200
253 9600 6 9600
250 4800 5 4800
244 2400 4 2400
232 1200 3 1200
208 600 2 600
160 300 1 300
N/A N/A 0 110
No Parity CP L2561 0
This datapoint indicates if parity generation and
checking should be turned on or off. It is set to 0 for
even parity serial byte protocol. It is set to 1 for no parity
protocol.
No Byte
Stuffing
CB L2581 0
When set to a 1, this datapoint disables the standard
communication protocol feature which inserts a 00
(NUL) byte after every 7EH (SOH) that is not the
beginning of a message. (This permits user written
communications software to determine the number of
bytes to expect in a response message.) It must be set
to 0 when using the Micro-DCI communications
software or equipment.
Datalink
Disable
DLD L257 0
When set to 0 , it permits full Datalink communication
capabilities. When set to 1, it disables Datalink
communication capabilities.
