Data is transmitted with a system and group address.

Data transmission begins as serial data is received— maximum

packet size is 530 bytes. All modules with the 0correct system

address, which receive the data packets, outputs the

data—error checking is optional.

Data is transmitted in packets with a system address, source

address, destination address, up to five intermediate repeater

addresses, and a 16 bit CRC error-check. If the packet is

received with a correct error check, only the destination module

will output the data and will also return an ACK transmission.

If the source module does not receive the ACK, it will retry

a further four times. DCD provides communications status.

Auto-connect and dial-up-control modes are available.

CTS/RTS flow control provided based on input

buffer availability.

freeware software package or by Hayes AT commands

Radio noise, signal strength and bit error rate (BER)

diagnostics included. Radio signal strength value available

on-line to host device.

Type Part No.
