Transmit Mode, Norm Ack Retry | Intermec 6710 specs

SECTION 4 " Configuration

Smaller fragments may allow successful operation in an environment with a high level of interference at the expense of throughput.

Transmit Mode

Transmit Mode modulates the transmit signal and sets the bits per second. Settings are:

	BFSK
	QFSK
	AUTO

Setting	Description

BFSK	Binary Frequency Shift Keying. Transmits at 0.8
	Mbps per second. Data is transmitted by shifting
	between two frequencies to represent one bit of 0
	or 1. BFSK has extended range over QFSK at the
	expense of throughput.
QFSK	Quadrature Frequency Shift Keying. Transmits at
	1.6 Mbps per second. Data is transmitted by shift-
	ing among four frequencies to represent two bits of
	0 or 1. QFSK has better throughput over BFSK at
	the expense of range.
AUTO	Automatically adapts the bit rate to the error
(default)	conditions. The transmit mode is automatically
	selected for the best range and throughput.

Norm Ack Retry

Norm Ack Retry is the number of times any unfragmented frame (QFSK or BFSK) is resent unsuccessfully before fragmenting. The prompt is:

Range is: 1..255
