Tait accessories TMAA04-04 Crossband Linking Cable Installation Instructions Introduction The TMAA04-04 crossband linking cable is used to connect the auxiliary connectors of two radios configured as a crossband repeater. Components in the TMAA04-04 are optomized for voice applications. Important: The radio does not meet the IP54 protection standard once the auxiliary connector rubber bung has been removed and a crossband linking cable has been installed. Care must be taken when the radio is being operated in an environment where there is water, dust or other environmental hazards. Installation 1. Remove the rubber bung that covers the auxiliary connector on each of the radios. 2. Plug each end of the crossband linking cable into the auxiliary connector on each radio. Radio Programming After the transmit and receive channels have been programmed for both radios, settings in the following forms must also be configured: ■ PTT form (refer to Table 1) ■ Programmable I/O form — Digital tab (refer to Table 2) ■ Programmable I/O form — Audio tab (refer to Table 3). If a repeater transmit tail is required, settings in the following forms must be configured in both radios: ■ PTT form (TM8100 radios only) (refer to Table 4) ■ Basic Settings form—Subaudible Signalling tab (TM8200 radios and optional for TM8100 radios) (refer to Table 5 and Table 6). Some of the settings shown in the tables are default settings and may not need to be changed. In all cases, refer to the online help of the programming application for more information. 402-00030-00 www.taitworld.com Crossband Settings in the PTT Form The following table shows the crossband linking settings required in the External PTT (1) tab of the PTT form.

This can be set to Busy Detect + Sub if the mute is to open only when valid subaudible signalling is present with the transmission. 2 TMAA04-04 Crossband Linking Cable © Tait Electronics Limited September 2005 Repeater Transmit Tail Settings TM8100 Radios If the transmitter requires a “tail”, then this can be set in the External PTT (1) tab of the PTT form. During the PTT deactivation delay period, any signalling, such as CTCSS or DCS, is still present. Table 4 Transmit tail settings in the PTT form, External PTT (1) tab (TM8100) Field Advanced EPTT1 Setting PTT Deactivation Delay up to 1000ms If a further transmitter tail is required, then this can be configured in the Subaudible Signalling tab of the Basic Settings form. During the lead-out delay period, no signalling, such as CTCSS or DCS, is present.

During the lead-out delay period, no signalling, such as CTCSS or DCS, is present.

On the receiving radio, inject an on-channel RF signal at a level of -70dBm, modulated to ±3kHz deviation (wide bandwidth channel) or ±1.5kHz (narrow bandwidth channel), at 1kHz AF. 2. On the transmitting radio, the resulting deviation should be: ■ ±3kHz (with a tolerance of ±200Hz) on a 25kHz wide bandwidth channel. ■ ±1.5kHz (with a tolerance of ±200Hz) on a 12.5kHz narrow bandwidth channel. Interface Specification The following table and diagram summarizes the signals used for the crossband linking cable on the radios’ auxiliary connectors and shows the interface between the cable and the radios.
