Introduction
Third Party
The Model 6300 IP Gateway works with most Zetron and third-party (non-Zetron)
consoles providing Tone Remote Control (TRC) or E&M signals. However, there are
some limitations when used with third-party consoles:
• The IP Gateway requires a 4-wire interface to the console; a Tx pair and an Rx
pair. It is not compatible with consoles that only offer a 2-wire connection.
• If used in conjunction with Zetron or third party interfaces or adapters, such as a
Radio Interface Module or Tone Remote Adapter, there may be additional
limitations imposed by those interfaces or adapters.
The Model 6300 IP Gateway also works with non-radio, specialty voice applications (e.g.
hoot-n-holler and intercom lines).
Radio Compatibility
The IP Gateway is compatible with the audio and PTT/COR signals of most radios, using
either the balanced 4-wire or unbalanced direct connection ports of the IP Gateway.
If a radio’s serial data is to be passed through the IP Gateway, the radio either needs to
use RS-232 or TTL serial data, or external third-party devices will be needed to convert
the radio’s electrical interface to RS-232 or TTL. The IP Gateway’s serial data signals
only include transmit and receive data – additional handshake lines such as RTS/CTS and
DSR/DTR are not supported. Radios that require these signals will not work with the IP
Gateway.
Note
Serial data protocols used by many devices such as mobile
radios may have stringent timing requirements. Operation over
IP networks can introduce delays which may prohibit the proper
operation of certain serial data protocols.
Network Compatibility
Several network parameters such as the type of switches, overall network speed, and
prioritization settings have a direct, measurable effect on a system using Model 6300 IP
Gateways. The following list identifies specific requirements.
Caution!
Installations for critical use should only use a reliable,
quality network that meets or exceeds all of the network
requirements.
