Figure 4 - Full-Featured HiPR-900 Front Panel (left); HiPR-900S Front Panel (right)
Only the front panel has connections and indicators. They are:
•
One standard RJ-45 auto-sensing 10/100 UTP Ethernet connection with Auto-MDIX. Supports
direct connection to both Terminal Devices and Ethernet hubs or switches without resorting to
crossover cables. LED indicators make it simple to verify that Ethernet cables and connections
are good.
•
Two DE-9F RS232 ports. Serial baud rates from 300 to 115,200 are supported. HiPR-900 units
are factory set (default) for 115,200 b/s, 8 bits, no parity, and 1 stop bit.
•
The antenna connector for the transceiver is a female 50-ohm TNC type. The HiPR-900 is de-
signed to operate with an antenna having a maximum gain of 10 dBi. Transmitting antennas with
higher gain are strictly prohibited (FCC and Industry Canada).
•
One TNC-type female antenna connector for the PD receiver (RX antenna used may be of higher-
gain than the RX/TX antenna)
Note: PD receiver is exclusive to the full-featured HiPR-900 version. RX antenna con-
nector will not appear on HiPR-900S version (Figure 4 right).
•
One right-angle power connector. The 10 to 30 VDC wide-range switching power supply permits
powering from 12 volt as well as 24 volt systems, and the high-efficiency switching design runs
cooler with less loss. The HiPR-900 can be supplied power at its DC input (10-30V) or its PoE
input; the DC input is given priority. The unit will switch between power sources according to the
transition table below. This minimizes the load on PoE Ethernet switches while allowing them to
possibly act as a backup to the local power supply.
