APPENDIX 3
Certain older and unusual receivers have formats other than those listed on page 11. Locations 250 thru 255 provide various
methods to duplicate these unusual formats. Included in these overrides is the ability to call and report to a personal pager.
The timer adjustment options allowed in locations 250 and 255 sometimes can compensate for substandard, or older
telephone exchanges. It is suggested that you call DAS technical assistance the first time you attempt to use these override
options.
LOCATION 250 - Inter-round time of a two round parity transmission. The inter-round time will be the number contained in
location 250 times 800 mSec. If location 250 is "0", the time is determined by the individual formats in locations 118 and 140.
LOCATION 251 - Inter-digit time of a pulse format. If the number programmed in location 251 is something other than "0", The
inter-digit time will be that number divided by the PPS. For example, if the number in location 251 is "10", and the format is a
20PPS format, the inter-digit time will be 10/20 of 0.5 seconds. For locations 252 thru 255, you must add the listed values for
the desired characteristics and program the sum in the appropriate location. If the value is not added for locations 252 and 253,
the converse mode will be enabled for those locations. If the value of 1 is not added to location 252, the transmitted frequency
will be 1900 Hz. If the value of 2 is not added to location 253, the communicator will not transmit hex digits. If neither of values
4 or 8 are added to location 253, the communicator will send messages at 40 PPS.
LOCATION 252 - The number programmed in this location will determine the selected default as desired.
