Configuring Your Scanner

3–19

Publication 2755-6.3

ENQ ONLY requires that the base/charger unit receive an an enquire
character (ENQ) from the host before sending data. With ENQ
enabled, the base/charger unit must receive an ENQ from the host
within a two second period after the last scan or a transmission error
occurs. The scanner will provide four short beeps to indicate the
error; the base/charger unit is ready to send again.

ACK/NAK with ENQ combines both ACK/NAK and ENQ options.

Serial Response Time-out

When enabled, this parameter determines the maximum period
allowed to elapse before the base/charger unit assumes the end of
transmission. The delay can last up to 9.9 seconds. The default
parameter is enabled at 2 seconds.

Stop Bit Select

The stop bit marks the end of each character transmitted and
prepares the receiving device for the next character in the data
stream. You can set the number of stop bits to either 1 or 2 to match
the host device. The default parameter is set to 2.

ASCII Format

When enabled, the scanner transmits data in an 8-bit ASCII format.
This allows the the base/charger unit to interface with devices using
that protocol. The default is 7-bit ASCII.

RTS Line State

When enabled, the parameter adjusts the RTS Line State since
certain hosts expect the RTS line to be in a certain state (high or
low). The default parameter is set to low.
