ESCRIPTION
The TRML series multi line tone remote allows users to reliably control up to four separate conventional and/or
trunked two way base stations and/or repeaters via twisted pair wiring. One TRML remote allows users to
communicate on 4 separate radios individually or a combination of 2 to 4 radios simultaneously. Incoming receive
audio signals are controlled by independent select and unselect audio controls with the capability of each line being
muted.
Programmable features include line enable/disable and select all enable/disable. The TRML does not require
additional software for programming. Data is stored in a nonvolatile EEPROM and will retain the data when power
is lost. Programming is accomplished using the standard front panel buttons on the face of the remote allowing
fully field programmability.
When a PTT occurs from the handset, front panel, optional desk mic, optional gooseneck, or optional headset
interface the other mics will mute to eliminate background noise during the transmission. Receive audio is
transferred to the handset earpiece when taken off hook.
Parallel Status Indication allows the remote to update when a channel change function is performed from another
remote on the system. The TRML activates the Parallel Transmit Indication (PTI) by lighting the TX LED when
parallel remotes key and can also be configured to mute the speaker by enabling the crossmute function to prevent
audio feedback when remotes are in close proximity.
Standard features include volume controls for selected and unselected lines, individual activity line indicators, front
panel PTT switch, LED transmit indicator, monitor function with LED indicator, intercom function with LED indicator,
select all function with indicator, individual receive mute switches with LED indicators, receive and transmit audio
compression, 2175Hz transmit and receive notch filters, PTI indication, crossmute, 2 wire and 4 wire selection per
line, locking quick disconnect power supply, and RJ45 connections to termination panels.
The TRML is available in many optional configurations. Some of the available options include: (-DM) Desk mic in
addition to handset, (-GN) Gooseneck mic replaces the handset, (-FS) Foot switch to activate PTT, (-CC) Contact
Closure PTT relay output, (-8F) Eight frequency control per line, (-SPK/JACK) 3.5mm jack for amplified speaker,
and (-SPKR) Speaker (external, amplified, requires 12VDC).
