5W 無線發射器 TX-125


TX125EN is one of the most powerful Gold Apollo transmitter for in-house paging solution that require paging and managing messages from PC. All paging and control is done via RS232 serial port.

The transmitter support 1 and 5 watts (switchable) output power, and the coverage is up to 1-1.5KM (1 Watt) and up to 3.5-5KM (5 Watt) in open space.

Based on POCSAG protocol, TX125EN transmitter is compatible to any POCSAG pagers, included alphanumeric/numeric/tone only/LED display/desktop pagers. This makes the TX125EN suitable for any in-house paging solution.

The transmitter offers friendly user interface with Gold Apollo GACOMP2 paging software, GACOMP2 software enable users to manage all pages.

TX125EN supports a wide variety of standard control protocols, including COMP1, COMP2, SCOPE, GACOMP2, TAP protocols.

TX125EN is capable to call up to thousands of pagers.
