MODEL LT8116
|
16 Channel Multiple Interface Multiplexer
|
- 16 Async Channels
- Speeds Up to 38.4 Kbps
- Power Redundancy & Fiber Optic Redundancy
- LEDs for "Tx," "Rx," "Alarm"
& "PWR"
- Field Interchangeable Interfaces: RS232, RS-422,
Dry Contact Relays
- Local & Remote Loopback Single Mode & Multimode
Rack Mount or Standalone
Applications
The LT8116 provides a particularly inexpensive
method for connecting large numbers of async terminals,
printers and status collecting devices. It is
also used in harsh environments where EMI/RFI
interference and lightning conditions may exist.
Description
The LT8116 is an affordable 16-channel fiber
optic multiplexer with interchangeable interfaces
and optional power/optical redundancy. It supports
data rates up to 38.4Kbps with no controls. Because
the electrical interfaces are modular, they are
interchangeable in 4-channel increments at any
time--before or after installation. Available
interfaces include RS-232 or RS-422. Fiber optic
connectors are ST (FC or SMA are optional); electrical
connectors are RJ11. Power is 9 to 12VDC or 115/230VAC
with an external power cube.
