The Encompass 4/4800 Multiprotocol Reader System does not include a real-time
clock. The dual-protocol Encompass 4/4800 Multiprotocol Reader internal timing var-
ies depending on the operative tag read mode and the type of tag in the read field.
Unless stated otherwise, values listed for timing-related command variables assume
an ID operational mode (64-bit ID data from eGo tags, ignoring ATA tags) and an
eGo-compatible tag in the read field and these values may vary.
