TU860 模塊總線
TU849是光模塊總線調制解調器TB840/TB840A冗余配置的MTU (module termination unit)模塊。
MTU是一個無源單元，具有雙電源連接，每個調制解調器一個電源連接，單個電ModuleBus連接，兩個TB840/TB840A連接和一個用于集群地址(1 ~ 7)設置的旋轉開關。
四個機械鍵，每個位置兩個，用于為正確類型的模塊配置MTU。每個鍵有六個位置，總共有36種不同的配置。可使用螺絲刀更改配置。
MTU可以安裝在標準DIN導軌上。它有一個機械閂鎖，鎖定MTU到DIN軌道。這個插銷可以用螺絲刀鎖上/解鎖。
終端單元TU848具有單獨的供電連接，可將TB840/TB840A連接至冗余I/O。終端單元TU849具有單獨的供電連接，可將TB840/TB840A連接至非冗余I/O。

The TU849 is a module termination unit (MTU) for redundant configuration of Optical ModuleBus Modem TB840/TB840A.
The MTU is a passive unit having connections for double power supply, one for each modem, a single electrical ModuleBus, two TB840/TB840A and a rotary switch for cluster address (1 to 7) setting.
Four mechanical keys, two for each position, are used to configured the MTU for the right types of modules. Each key has six positions, which gives a total number of 36 different configurations. The configurations can be changed with a screwdriver.
The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to the DIN rail. The latch can be locked/unlocked with a screwdriver.
Termination unit TU848 has individual power supply connections and connects TB840/TB840A to redundant I/O. Termination unit TU849 has individual power supply connections and connects TB840/TB840A to non-redundant I/O.
