Direct Link Cable
The Direct Link cable connects the 2x TM1-Mk3+ system controllers together for monitoring and control
purposes. The cable connects to the WatchMan connector on each unit:
TallyMan Redundancy Panel (TMRP)
The TMRP is a hardware unit dedicated to redundancy operations. It can be mounted onto a 1RU bracket
(supplied) for use in technical furniture, or into a racking system. (Other mounting methods are
available.)
The unit provides real-time status of the redundancy system as well as offering user controls to change
functions such as Failover mode and activating a unit. In addition, the unit has GPO to provide external
systems or changeover units with the active status of each TM1-Mk3+ unit in the system.
Note the buttons (with LCD displays) used on the TMRP are limited to 6 characters, so some terms and
messages have been abbreviated to ensure they fit on the display.
The TMRP has four buttons:
Functional button dedicated to the status and operation of the Primary TM1
Functional button dedicated to the status and operation of the Backup TM1
Functional button dedicated to the status and operation of the failover mode mechanism
Button dedicated to enabling the operation of the functional buttons
