Pinout and Wiring
Gateway Relay Outputs
The two relay outputs each accept a 2.5mm jack plug. These are individually controlled SPST relay contacts. Comark can
supply jack plugs for wiring external equipment to be activated by the Gateway.
The maximum lead length for the relay outputs is 3m.
Ensure that any external equipment presents only a low voltage on the jack so as to prevent any chance of
personal injury due to electric shock should the jack plug become disconnected.
FCC Approvals
The RF500 Gateway and Transmitters comply with Part 15 of the FCC Rules. Operation is subject to the following four
conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that may cause undesired operation.
• To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotropic radiated power (e.i.r.p.) is not more than that permitted for successful communication.
• Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
Transmitters must be placed greater than 20cm from the body.
