+5 Vdc, nominal (+4.75 to +5.25 Vdc).
60 mA, typical at +5 Vdc. Average power dissipation is 0.3 W, typical.
Supply must be capable of sourcing 100 mA, minimum.
Total noise and ripple requirement must be less than 100 mV (p-p) for
frequencies below 1 MHz, and less than 50 mV (p-p) for frequencies above 1
MHz.
EIA 232E (Serial RS-232), DCE configuration. 8 Data Bits, 1 Stop Bit, No
Parity, Full Duplex.
Hardware handshaking: RTS/CTS
DSR is pulled HIGH (>+3V) by the 2500S when connected and powered. DTR
is ignored
