101B224-07 DM61 RS-485 SERIAL ADAPTER
Description
The 101B224-07 converts the serial output of the DM61 meter to
balanced, full or half-duplex RS-485 signals.
The 101B224-07 has a removable screw terminal connector for the
RS-485 terminals which includes Transmit Data (DO) and (/DO),
Receive Data (DI) and (/DI), and Signal Ground. The adapter is
provided 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 101B224-07 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 RS-485 bus to the
meter, and a Receive Data (RX) LED to show when the adapter is
receiving data from the DM61 meter.
