IP9xx Series
1.0 Overview
The IP Series is a high-performance wireless ethernet bridge and
serial gateway. Alternately, a Master IP Series unit may be config-
ured to operate as a wireless ethernet router (and serial gateway).
When properly configured and installed, long range communications
at very high speeds can be achieved.
The IP Series operates within the 902-928MHz ISM frequency band,
employing frequency hopping spread spectrum (FHSS) and also, for
1.1Mbps operation, digital transmission service (DTS) technology.
They provide reliable wireless ethernet bridge functionality as well
gateway service for asynchronous data transfer between most equip-
ment types which employ an RS232, RS422, or RS485 interface.
The small size and superior performance of the IP Series makes it
ideal for many applications. Some typical uses for this modem:
1.1 Performance Features
Key performance features of the IP Series include:
1 920-928MHz, which is license-exempt within North America, may need to be
factory-configured differently for other areas: contact Microhard Systems Inc.
 SCADA
 remote telemetry
 traffic control
 industrial controls
 remote monitoring
 LAN extension
 GPS
 wireless video
 robotics
 display signs
 fleet management
 transmission within a public, license-exempt band of the radio
spectrum1- this means that the modems may be used without
access fees or recurring charges (such as those incurred by
cellular airtime)
 maximum allowable transmit power (1 Watt)
 longest range
 transparent, low latency link providing reliable wireless IP/
ethernet communications with constant baud rate over
distance
A BRIDGE separates two network
segments within the same logical
network (subnet).
A SERIAL GATEWAY allows
asynchronous serial data to enter
(as through a gate) the realm of IP
communications.
The serial data is encapsulated
within UDP or TCP packets.
A ROUTER forwards data across
internetworks (different subnets).

2.0 Quick Start
This QUICK START guide will enable you to promptly establish basic
IP connectivity between a pair of IP Series in a point-to-point (ref.
5.1) configuration.
Note that the units arrive from the factory with a Radio Configuration
of ‗Remote‘ and the Local Network setting configured as ‗Static‘ (IP
Address 192.168.1.254, Subnet Mask 255.255.255.0, and Gateway
192.168.1.1).
2.1 Factory Default/Reset Method
2.11 Required Materials

IP9xx Series
2.0 Quick Start
The ethernet connections are dependent upon what is available to
work with for the test configuration. For the purposes of this QUICK
START, the assumption is that a LAN connection is available (with
Internet connectivity) and that the PC is connected to this LAN.
 Disconnect the PC‘s LAN connection from its NIC card
and insert the now ‗loose end‘ of the ethernet patchcable
into the rear ETHERNET RJ45 connector at the rear of
the MASTER IP Series.
 Using a CROSSOVER cable, connect the PC‘s NIC card
RJ45 jack to the ETHERNET RJ45 connector on the RE-
MOTE IP Series.
At this point there is a wireless connection between the PC and the
LAN, and you should be able to go about your typical networking ac-
tivities, including accessing the Internet (via the LAN).
Also, by opening a web browser and entering the IP address of either
IP Series, you will be taken to the respective unit‘s Web User Inter-
face LOGIN window.
If communications not available as outlined above:
 Verify the RSSI LEDs on the front of each IP Series are
illuminated.
 Verify TX (red) LED activity on the front of each IP Se-
ries.
 Observe the rear of each IP Series, specifically the
ETHERNET connection: the green LINK LED should be
illuminated (indicating proper cabling) and the amber
(ACTIVITY LED) should also be flickering—indicating
DATA traffic at the ETHERNET connector.
 If using Windows XP, the firewall function could inhibit
desired data traffic. Anti-virus software may also have a
negative impact.
To connect an IP Series to a PC,
an ethernet CROSSOVER (not a
straight-through) cable must be
used.

IP9xx Series
3.0 Hardware Features
On the front of the IP Series are, from left to right:
 COM2 Port (DCE)
 CFG pushbutton
 TX LED
 RX LED
 SYS LED
 RSSI LEDs (3)
Image 3A: Front View of IP Series
The IP Series is a fully-enclosed unit ready to be interfaced to
external devices.
Any IP Series may be configured as a Master, Repeater (or
Repeater/Slave), or Slave. This versatility is very convenient from a
‘sparing‘ perspective, as well for convenience in becoming very
familiar and proficient with using the device: if you are familiar with
one unit, you will be familiar with all units.

3.0 Hardware Features
The COM2 Port (DCE) is used for two purposes:
 Text User Interface (local console port) at 115.2kbps
(using MHS-supplied BLACK RJ45-DE9 cable (P/N
MHS044000) and HyperTerminal (or equivalent).
 User data (serial, RS-232, wired for RxD, TxD, and SG)
The COM2 port is NOT an
Ethernet port.
CFG Button
Holding this button depressed while powering-up the IP Series will
boot the unit into FLASH FILE SYSTEM RECOVERY mode. The
default IP address for system recovery (only - not for normal access
to the unit) is static: 192.168.1.39.
(For more information on performing a firmware upgrade, see
Appendix B and Section 6.1.9.1.)
If the unit has been powered-up for some time (>1 minute),
depressing the CFG Button for 8 seconds will result in FACTORY
DEFAULTS being restored, including a static IP address of
192.168.1.254. This IP address is useable in a Web Browser for
accessing the Web User Interface.
