B.1.1 CONFIGURATION
To initialize the instrument for binary communications, configure the instrument as described in Ta-
ble B-1, Column 3 (Set Up ).
Table B-1. Communication Module
Purpose: This module is used to configure the Datalink port parameters (e.g., baud rate, parity
selection, etc.).

Attribute
Instrument
Address B01 S 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 B02 S 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 L256 0 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 L258 0 0 When set to a 1, this datapoint disables the standard
Micro-DCI
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
Micro-DCI
communications software or equipment.
Datalink
Disable L257 0 0 When set to 0 , it permits full Datalink communication
capabilities. When set to 1, it disables Datalink communication
capabilities.
Note: S = Select a value from the Attribute column. Use all other datapoint values as shown.
