Harris M7100 Wireless Interface Option
Both channels on the Harris Dual Channel Wireless Control Card must be Harris interface
channels.
Recommendations
The following recommendations are made concerning overall system design:
Each of the radios should operate from its own 12VDC power supply.
For each radio in the system to achieve proper performance and stability, it is important
that adequate separation be provided among all of the radio antennas for the system.
Orion Dual Channel Wireless Control Card Configuration
Switches
The Orion Dual Channel Wireless Control Card has several switches that, for earlier
firmware versions, required configuration before the card is installed in the Series 4000
system. The card has four switches for each of the two channels (see Table 56 ); this table
is provided as a reference only for earlier firmware versions.
Warning!
Harris M7100IP radios with certain firmware revisions may
experience lock-up if the receive carrier detect signal changes
state too frequently (an example of this is a field unit in motion
in a fringe reception area). If this occurs with your radio, it
may be necessary to cycle the radio power supply in order to
restore normal radio operation. This potential problem also
applies to Harris J725M (Jaguar) radios.
STOP
Note
For firmware versions 1.26 and later, the DIP switches have no
effect. Full Duplex is always on. BTI and OPT are always off.
For prior firmware versions, refer to the manual delivered with your
hardware, or revision F of this manual (025-9533).
