Loading to External Input Channels (DX2000 Only)
The DX inputs the data loaded from the server to the external input channel as a 16-bit
signed integer type.
• Example 1
Load the values of the 16-bit unsigned integers assigned to register 30001 of
instrument C to external input channel 201.
30001 201 16-bit unsigned integer
External input channel Register of instrument C
Command setting
R 201 - 201 3 30001 UINT16
• Example 2
Load the values of the 32-bit unsigned integers assigned to registers 32001 and
32002 of instrument C to external input channel 202. Only the smallest register
number need be specified in commands.
32-bit unsigned integer

Writing Measured Values to the Server
• Example
Write the measured value (16-bit signed integer) from channel 1 to register 40001 of
instrument A.

Measurement channel Register of instrument A
001 40001
Command setting
W 001 - 001 1 40001 INT16
Writing Computed Values to the Server
• Example
Write the computed values (32-bit signed integers) from channel 101 to registers
40001 and 40002 of instrument A, in the order lower 16 bits/higher 16 bits. Only the
smallest register number need be specified in commands.
