101B224-06 DM61 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.
