LRI512

POOL EAS

Command Code = 0xA2

When receiving the POOL EAS Request, all

LRI512 with the non-volatile EAS bit set generate

the EAS signal.

Request parameter (Table 52 or Table 53):

– No parameter

POOL EAS Response Format when the request

frame is correctly received

The LRI512 generates a continuous stream of 256

bits at ‘0’ using the One or Two sub-carrier modu-

lation at Low data rate ended by 2 CRC bytes.
