♦ Checking the Model 6203 jumper settings:
1. Check that the Dual RX Audio Source Summing jumper is installed on JP14
(instead of a normal 2-pin jumper). This jumper will be three pins wide and have a
small PCB attached to its top.
2. Check that the COR Pull-up (JP9) jumper is in the “A” position.
3. Check that the VOX Control (JP3) jumper is in the “B” position.
Programming Changes to the Model 6203
This sub section covers changes that need to be made to the programmable settings in the
station alerting units in order to ensure proper system operation in both normal and backup
operating modes. The settings changed are primarily timers. You should not have to alter
the settings concerning unit type (6203 or 6204) or ID number.
♦ Checking the serial settings for the station alerting units:
1. Connect a compatible serial cable (see J1 Serial Port Pinout on page 153) between
your computer and socket J1 on the transponder board.
2. Set switch SW1-8 to the ON position.
3. Using a serial terminal emulation program (such as HyperTerminal), set up a
connection for the COM port to which the cable is connected. The settings should
be: 9600 baud, 8-bit words, 1 stop-bit, no parity checking, and flow control set to
none.
4. Hit the SPACE bar three times to open the Model 620x configuration main menu.
5. Enter a “1” to open the Station Configuration menu. Confirm the items 1 and 2 are
correctly set.
