6.0 Interfacing to the RU00-M08
 Power and Ground
All circuits on the RU00-M08 are powered from inputs at pin 11 and 12 of J6. The RU00-M08
operates with any supply voltage DC 48V +/- 10%. Because the individual supplies within the part
are regulated on the RU00-M08, a large amount of supply filtering is not required.
All 4 available ground pins of J6. Providing a highly conductive path from the M200 ground to a
continuous ground plane (by use of numerous vias to the ground plane) and as much ground
conductor area as possible on the outer layers of the user PCB will help to reduce the M200
temperature rise during operation.
 Communication
The RU00-M08 has one UART ports, each of which utilizes 3.3V CMOS I/O over a pair of pins. The
UARTs are compatible with a standard RS-232C serial port through an appropriate level translator
IC. The user’s host processor issues IRI commands to the HOST UART, which can be configured
for any standard UART data rate for 115.2k, 230.4k, 460.8k and 921.6 kbaud. The default rate is set
to 115.2 kbaud.
 RF
The RU00-M08 is configured for monostatic operation, which requires only a single RF I/O pin for
full duplex communication. The output must be routed to the antenna via 50 ohm cable. No coupling
capacitor is required given that the RF pin is AC-coupled internal to the RU00-M08. To maximize the
radiated power (and corresponding communication range), the length of the transmission line
between RU00-M08 and antenna should be made as short as possible.
 Enable
Pin9 of J6 on the RU00-M08 comprises the ENABLE signal.
 Wakeup
Pin3 of J6 on the RU00-M08 comprises the WAKEUP signal.
 Health and Status
Pin1 and Pin2 of J6 is a dedicated digital output that indicates the HEALTH & STATUS of the
RU00-M08.
