The DB9 socket input is used as a setting port. Settings, such as the delay compensation
value can be made through this port.
Further setting can be made through an internal four-position DIP switch.
The four-position DIP switch on the printed board is defined as follows:
Switch 1 is spare
Switch 2: When the signal is ON, the input signal is NOT calculated.
Switch
3: No compensation will be performed when “ON”.
Switch 4
: When “ON”, it is used
as “IRIG
-
B input I board”
; When "OFF", it is used as "IRIG-B
Input II Module".
The "Delay Compensation Input Module" can be set via the "GPSDelayTimePanel.exe"
software via the serial port on the front panel. The "setting" port is a standard DB9 male
connector.
The delay compensation of the "Delay Compensation Input Board" and "Delay
Compensation Output Board" is set by
Kehui’s
"GPSDelayTimePanel.exe" software. The
software sends the delay compensation value by sending a serial message to the delay
compensation module.
