Solutions for an evolving world.

• Optical Source 850 nm (infrared) VCSEL

transmitter Typical transmit level —12.0

dBm Maximum output level —3.0 dBm

• Power Requirements Receives adequate

power from a single EIA-232 TXD data line

connected to Pin 3 of the DB-9 connector.

Additionally, the SEL-2812 accepts power

applied to Pin 1, 7, or 8.
