A6.2.1.6 Onboard DIP-Switch Settings
An 8-switch dip-switch is located on the front of the input circuit board adjacent to the power switch.
Positions 1 through 6 change the output designation number from 0 to 63 in binary format (see String Identifier
table in NMEA-0183/IEC 61162 String Identifier Configuration section below), without restarting (i.e., all 6 in the
ON position would give an output of $DIS63).
Switches 7 and 8 control the output repetition rate, as follows (Code version 09/03):
Switch 7 8
Maximum No of DataDiscrete:
Daisy-Chaining
1 Hz OFF OFF 3
1/3 Hz ON OFF 4
1/6 Hz OFF ON 5
1/10 Hz ON ON 10
Table A6 - 8 - Onboard DIP-switch settings
Changes to the output repetition rate can also be made without restarting the device.
NOTE! The above provided daisy-chain settings allow for a maximum string return.
A6.2.1.7 Discrete Input Voltage Levels
Minimum Voltage Levels (V) Maximum Voltage Levels (V)
Low Voltage Input (Jumpers ON) 3 60
High Voltage Input (Voltage OFF) (130K res 23.0 VDC) 170
