General |
Serial Port Interface |
RS-232 compatible. 1200 to 38400 baud operation with 1 start, 8 data, optional parity, and one stop bit. |
Power Supply |
9-16 VDC. PDL Rover quiescent/receive power consumption 0.3W. PDL High Power Base quiescent/receive power consumption is 1.9W. PDL High Power Base in the low/high RF power setting consumes 13W/125W during transmission. The PDL Low Power Base quiescent/receive power consumption is 0.9W. The PDL Low Power Base when transmitting consumes 5W/11W. (PDL Base power consumption measured at 12.5 VDC.) |

Modem |
Transmission Rate |
19,200 or 9,600 bits per second (Four-level FSK) 9,600 or 4,800 bits per second (GMSK) |
Transmission Protocols |
Transparent, packet switched, auto-repeater, fast asynchronous, Trimtalk™. |
Forward Error Correction and Detection |
With FEC enabled, data is encoded by a block code. The data is interleaved in blocks of 20 words, giving burst error correction capabilities for up to 20 consecutive corrupted bits. 16-bit CRCs are generated and sent with every block of data providing 100% error detection for burst errors shorter than 16 bits, and 99.9984% detection of all other burst errors. |
Modulation |
Gaussian Minimum Shift Keying (GMSK) with BT of 0.5 (4800, 9600 bps link rate). Four-level FSK (9600, 19200 bps link rate). |
