Z-Max Surveying System Operation and Applications Manual
The Thales radio parameters are described in order as follows:
Radio serial port setting. (PORT)
This is the serial port to which the radio is connected. Valid settings are B or
D. Port D (default) is the internal port and must be selected if the
Communication Module is being used. If an external Thales U-Link radio is
used, the radio should be attached to serial port B. When this parameter is
set to port B, the port protocol will be switched to RS-422 (required for Thales
radios). Any other port selection will change the port B protocol to RS-232. To
select a port, press ENTER to access the submenu, scroll to the desired port
setting and press ENTER to select it.
Radio Baud Rate. (BAUD)
This submenu sets the baud rate of the radio serial port. Valid baud rates are
300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 56800, and 115200. The
default is 19200 and should not be changed. To select the baud rate, press
ENTER, scroll to the desired baud rate, and press ENTER to select it.
Load radio parameters to the receiver. (LOAD)
Press the ENTER key to load Thales radio parameters to the receiver. This is
done to ensure that any other active data links are fully turned off and the
receiver is ready to use the Thales radio. Perform a LOAD before attempting
to send user parameters (PROGRAM) to the receiver.
Channel selection. (CHN: **)
Displays and sets the radio frequency channel number. Channel numbers
range from 00 to 15 and each channel number is linked to a particular radio
frequency set at the factory. To set the channel number, press ENTER and
use the control keys to pick a channel number and press ENTER to select it.
Receive frequency. (RX: ***.****)
Displays the receive frequency in MHz. This field will display the receive
frequency matched to the channel number (CHN) parameter.
Transmit frequency. (TX: ***.****)
Displays the transmitter frequency in MHz. This field will display the transmit
frequency matched to the channel number (CHN) parameter.
Frequency (FRQ: ***.****)
Displays the current receive/transmit frequency. This field is useful when the
frequency cannot be found in the channel table, since in this case, both RX
and TX will show 0. When the current frequency matched the channel table,
RX or TX will be equal to FRQ.
