MOBILE DATA
The ORION radios when operating in the EDACS configuration permit
either voice or data calls to be transmitted or received. The radio can handle
only one type of call at a time; however, selection of either data or voice is
selected transparently by the operator through normal usage of the radio.
Data communications is not supported in the conventional mode.
The mobile radios may be connected to Mobile Data Terminals (MDT) or
to a host computer. Any RS-232 compatible device that supports the Radio
Data Interface (RDI) protocol (Version 1.91 or greater) may be connected to
the mobile radio. Support for MDT's or host computers is a programmable
option per radio. Additionally, radios programmed for host computers may
also be programmed for data only operation (no voice calls transmitted or
received).
Turn the power of the radio OFF before connecting or disconnecting any
cables, including the data cable. Also, turn the power of the radio OFF
when docking or undocking a connected laptop computer. Failure to
turn the power of the radio OFF may damage the radio, requiring the
replacement of an internal non-user servicable fuse.
