Cellular Radio Address

Auto Radio Address

If Auto radio address is enabled, the 7530 G2 requests an automatically assigned
radio address. Manual radio address is displayed in grey text indicating that it
cannot be accessed.

Manual Radio Address

The value entered in the Manual Radio Address parameter is used to identify
the 7530 G2 over the radio link. A unique value from 1 to 3840 must be assigned for
each unit.

Note: This parameter is set to ‘0’ (an out-of-range value) by default to block

radio communication when the unit is initially powered up. This prevents
several new hand-helds from attempting to communicate with the same
default terminal number at initial power up. Once the default value is
changed, it cannot be set back to ‘0’.

Polling

The default values for the Polling parameters are dependent on the value assigned to
the Modulation / Baud Rate parameter in the Radio tab.

Table 5.3 Polling Parameters

Sync Delay

Warning:

This parameter should not be changed from its factory setting
without a clear understanding of radio protocol timing.

The “Sync Delay” parameter specifies the delay between the base station
transmission and the first response window, measured in milliseconds. The value
assigned to this parameter must be compatible with other hand-helds and base
stations in the system. The allowable range for this parameter is between 1 and 40.
