Description
The R.F. Solutions 232C-868FR1 radio modem provides fast and reliable RF data communications at
an exceptionally competitive price. Whilst the RF modem is simple to use it is also highly adaptable and
can be used in a wide variety of applications.
The modems can be configured for various operating modes to
provide:
1. An ‘invisible’ RS232 point to point link, reproducing the
function of a half duplex RS232 cable.
2. A RS232 point to point link with data flow control to provide
data verification.
3. A functionality similar to that of a client/server network,
where each modem is assigned an address with a
maximum of 255 clients per network and a maximum of
65535 networks.
4. Point to point data transfer for up to four digital I/O signals
with continuous resend and automatic data
acknowledgement.
The modem is supplied in a tough ABS enclosure, with wall mounting lugs. The external 868MHz
antenna offers a range of up to 600 metres line of sight. The modem is supplied with an RS232 cable
and requires only a 9-12Vdc power supply.
