LOCAL/REMOTE ELECTRONIC SWITCHES
3. Installation and Configuration3.1 Before You Install
Check the box and its contents before you begin installing your Local/Remote
Electronic Switch. You should have received one Switch unit, one AC power supply,
and one copy of this manual. If you didn’t receive all of these items, or if they have
sustained damage that does not seem to be shipping-related, notify Black Box right
away. If they have sustained impact or water damage that seems to have happened
during shipping, notify both Black Box and the shipping carrier immediately.
Unpack the box carefully. We recommend that you save the original container
and its packing materials in case you need to ship the Switch later.
You’ll need to install the Switch within 6 feet (1.8 m) of an AC outlet. Also,
keep the Switch away from water and extreme temperatures.
Make sure you have the proper cables or adapters. Whatever interface you want
to switch (RS-232, RS-422, RS-485, V.35, TTL, etc.), you must use either cables with
DB25 male connectors or adapters that convert the interface from your cables’
connectors to DB25 male connectors. To perform remote switching, you must use
an appropriate length of cable that has at least four wires. If you intend to connect
it to the Switch’s internal terminal block, this cable must be unterminated at the
Switch end. If you intend to connect it to the Switch’s “REMOTE” connector, this
cable must have wires pinned to Pins 3 through 6 of a male RJ-45 connector at the
Switch end. (If you must use existing cables that do not meet these requirements,
call Black Box Technical Support; we might be able to provide adapters or create
a special product for you.)
