This section contains example programs that illustrate data transfer between
the ID Sensor Unit and the CPU of the PC. Six communication commands
(Write, Auto Write, Read, Auto Read, Clear-all, and Auto Read/Write Abort)
can be used.
Also included in this section are a description of Monitoring functions and an
explanation of Command Processing Time and Turnaround Time.
The following conditions apply to the example programs in this section:
1,2,3... 1. The ID Sensor Unit unit number switch is set to 0.
2. The command data is stored in the DM area of the CPU.
Refer to 2-3 The User Program for an overview of program operation.
This section illustrates program examples of the Write, Auto Write, and Clear-
all commands.

Data to be written to Data Carrier,
13
numbers 10 through 14 (5 bytes)
2A
If the number of bytes to be written to the Data
00
Carrier is odd, shift codes 2A and 0D forward
one byte and write 00 into the last 8 bits.
Sets the number of words in the
MOV (21)
command data (7 in this example)
#0007
Word n+1
101
Sets the beginning word where the
MOV (21)
command data is stored (DM 0000
in this example).
#0000
102 Word n+2
(Bit in IR area) Holds the status
10900
until the ID Sensor Unit begins ex-
ecuting the command.
