The data protocol of the output data is identical to the data going into the transmitter. No
modifications are made to the data stream from the source device except for baud rate.
The radios transmit data at 19,200 BAUD over the air and they can be configured in a variety of
ways to optimize the system for throughput, data reliability, and range. Contact MGPI for further
information.
2.2.3 Radio and Network Adaptor Configuration
The radios and the network adaptor can be reconfigured using any terminal program, such as
Windows HyperTerminal, to change parameters such as: Serial Protocol, Network Address, Over-
the-Air Radio Channel, etc. Refer to Position 3 section and Appendix 2.
The
rotary switch on the front panel can be used to select the following functions (as depicted in
Table 2 below):
Table 2: Communication Mode Summary
Position Mode Description
1 TX & RX NET, RX ONLY RS-232 Operate Base, Transmit & Receive using
Network, Receive Only using RS-232
2 TX & RX RS-232, RX ONLY NET Operate Base, Transmit and Receive using
RS-232 , Receive Only using Network;
Configure Radio 1
3 CONFIG NET OR RUN RADIO2
RS-232 Configure Network card, Operate Radio 2
using RS-232
4 REPEATER MODE WITH RS-232
MONITOR
Operate Base in Repeater Mode, monitor
using RS-232
Further description of the Communication Modes follows:
Position 1: TX & RX NET, RX ONLY RS-232
In this position, the base transceiver is configured to transmit and receive using the Network
Interface Adapter (NIA) and/or receive only using the RS-232 port (no transmit capability via RS-
232 port)
Position 2: TX & RX RS-232, RX ONLY NET
In this position, the base transceiver is configured to transmit and receive using the RS-232 port,
and/or receive only using the NIA (no transmit capability via the NIA). The radio can also be
configured in this mode position and requires a specially designed software program.
CAUTION: The WRM2 Radios are optimally configured for use with all WRM2
components and should not be modified. Contact MGP Instruments for further
information.
Position 3: CONFIGURE NET OR RUN RADIO 2 RS-232
This is the same as for Radio 1 if the base has the optional second radio installed.
