MRS100 / MRS100A
SETTING UP
The MRS100 / MRS100A is a communication adapter designed
to convert data from a Mitutoyo device to RS-232 format for use
with a PC or other device. A typical application is shown below
in which a Mitutoyo travel display mounted to a Mark-10 test
stand is connected to a PC using a Mitutoyo cable (available
separately) and MRS100A communication adapter:
09-1048A

USING THE MRS100 / MRS100A
Connect the Mitutoyo device as shown in the figure above. Set
the communciation parameters of the RS-232 channel to 1200
baud, 8 data bits, 1 stop bit, and no parity.
Transmission of data can be initiated by the RS-232 device or
software, in which case the MRS100 / MRS100A will automatically translate the data and transmit to the RS-232 device.
However, the RS-232 device can request data from the instrument by transmitting ASCII “?” or “X”, followed by <CR> or
<CR><LF>. Note that no separate power connection to the
MRS100 / MRS100A is required, as the power available from
the RS-232 channel is sufficient for its operation.
