Data Cable
The data cable carries the RS232 signal from the GasFinderFCr to an external computer,
which stores and displays the data. The cable length should not exceed 30m. If a longer
distance is required, other options are available:
RS485: This allows a twisted pair of wires to carry the data for 200 to 300m.
Fibre-optic modems: These are very small units connected with a multi-mode fi breoptic cable.
Distances covered can be many kilometers.
Wireless modems: These are usually spread-spectrum type and can transmit data over
distances limited by line of sight.
Cable Connections, Power
The GasFinderFCr will accept a power source at 100-250V, 50/60/440Hz, or 120-300V DC. A
power cord is supplied. If necessary, the plug may be removed and a local plug connected with
appropriate pins or the cord wired directly to a circuit breaker or fuse.
In areas where the power is intermittent, the use of an Uninteruptable Power Supply (UPS) that has a
minimum rating of 200VA is recommended.
An internal 3 amp fuse is accessible at the rear
of the
GasFinderFCr .
