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.

Modulation / Baud Rate	Sync Delay	Window Delay	Poll Timeout
4 Level / 19200	17	20	20
4 Level / 9600	17	23	25
2 Level / 9600	17	19	22
2 Level / 4800	25	23	37

	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.
