Note: Although this module is still available, it is not recommended for new designs. SIXNET recommends using an ET-GT-ST-2 I/O Concentrator to control each additional 20 modules. This intelligent controller improves system performance and reliability and removes ST-Bus distance restrictions.

ST-EX-001-20U Usage Tips

Use the ST-EX-001-20U after each group of 20 SixTRAK I/O modules, or to provide a one-time ST-Bus cable extension of 50 feet. This expander provides two buffered ST-Bus ports, which may have a total cable length of 50 feet.

Refer to the ST-Bus Wiring Guidelines for more information.
