Integrating HDS800 into Your Application
Base With Ashtech Radio Transmitter
Script
In the example below, it is assumed that the receiver will
generate differential data in RCTM V3.0 format. You may
replace RT3 with RT2 (RTCM2.3), ATOM, CMR or CMP
(CMR+), or DBEN. In the connection between the receiver
and the radio transmitter, port A is necessarily used on the
receiver side.
See $PASHS,RTC,TYP, $PASHS,RNX,TYP or
$PASHS,CMR,TYP if you want to change the default
messages and periods.
Action Command
Set the name of the antenna connected to
the receiver: $PASHS,ANP,OWN, ASH111661
$PASHR,ACK*3D
Set the antenna reduction mode to ON,
so that all coordinates refer to the ground
mark:
$PASHS,ANR,ON
$PASHR,ACK*3D
Set the antenna height (for example a
slant height of 1.45 meters was mea-
sured):
NOTE: When a slant height is entered,
you also need to enter the antenna radius
and the ARP-to-SHMP vertical offset
(negative if ARP is below SHMP).
$PASHS,ANT, 1.45 , 0.0921 , -0.0516
$PASHR,ACK*3D
Enter the coordinates of the base:
$PASHS,POS, 4717.93777 , N ,
130.541864 , W , 87.007
$PASHR,ACK*3D
Set the type of the radio transmitter and
the serial port to which it is connected
(port A necessarily):
U-Link TRx:
$PASHS,RDP,TYP,A,MDL
$PASHR,ACK*3D
Radio transmitter 800986:
$PASHS,RDP,TYP,A,MGL
$PASHR,ACK*3D
Set the baud rate of the port connected to
the radio (port A; 19200 Bd necessarily): $PASHS,PRT,A,6
$PASHR,ACK*3D
Select the RS422 mode for port A:
$PASHS,MDP,A,422
$PASHR,ACK*3D
Set the radio transmitter (channel num-
ber, protocol, air link speed):
U-Link TRx:
$PASHS,RDP,PAR,A,MDL,
3 ,,2, 4800
$PASHR,ACK*3D
Radio transmitter 800986:
$PASHS,RDP,PAR,A,MGL,
3 ,,2,4800
$PASHR,ACK*3D
