101B224-06 RS-232 Serial
Adapter
Description
The 101B224-06 converts the serial output of the DM61
meter to an unbalanced, full-duplex RS-232 signal.
The RS-232 port has a female DB9 connector with pins
2 (RX output), 3 (TX input), and 5 (Signal Ground). Pins
7 (RTS) and 8 (CTS) are tied together, and pins 1 (CD),
4 (DTR), and 6 (DSR) are tied together. The adapter is
powered by the DM61 meter M-Link connection.
Baud rates are adjustable and handled by the DM61
(see the DM61 Instruction Manual for more details).
The 101B224-06 has three diagnostic LEDs: a Power
(P) LED to show when the adapter is powered properly,
a Transmit Data (TX) LED to show when the adapter is
sending data out from the PC side, and a Receive Data
(RX) LED to show when the adapter is receiving data
from the DM61 meter.
