Can you tell me the model of this receiver? Q. What chip set does this receiver use? Q. What NMEA sentences does this unit output in the default mode? A. $GPGGA, $GPGLL, $GPGSA, $GPRMC, $GPVTG, $GPGSV. Q. Can you tell me if the GPS receiver will output the 1 PPS without connection to RS-232? A. Yes, 1 PPS is available on Pin 19, Normally low with 100ms TTL high pulse once every second. Q. The description states that this unit has an RS-232 level shifter installed. Does this mean that the unit can be connected directly to a PC without the need for a level conversion and inversion circuit? A. Correct, please refer to the above table "Minimum connections to make receiver work:" Q. Is there a way to disable or remove the RS232 driver? Q. Is it ok to connect VCC_5v and antenna power to the same 5V supply (assuming a 5v antenna is used)? Q. Do you have antennas for this receiver? Q. If I want multiple receivers do you offer a discounted price? Q. Will I get an email from you when I complete the purchase? Please, if you do not receive an email with your Delivery Confirmation number with in 24 hours, send me a quick note and I will manually look it up for you. Frequently asked Questions - Warranty Policy: Q. I was just wondering if you would give a D.O.A. guarantee? (please look at our rules and privacy policy) |
