4.6 Communication Card Specifications
The following tables list the specifications for each type of communications card.
Serial Communication Cards Specifications
EIA-232D (RS-232) CARD
Meets EIA-232 (RS-232) standard for single-ended
data transmission over distances of up to 15 m
(50 ft).
Data Rate: Selectable from 300 to 9600 baud,
depending on the configuration software used.
Format: Asynchronous, 7 or 8-bit (software
selectable) with full handshaking.
Parity: None, odd, or even (software selectable).
EIA-422/485 (RS-422/485) CARD
Meets EIA-422 (RS-422) and EIA-485 (RS-485)
standard for differential data transmission over
distances of up to 1220 m (4000 ft).
As many as ten devices can be connected on an
EIA-422 (RS-422) bus.
As many as 32 devices can be connected on an
EIA-485 (RS-485) bus.
Data Rate: Selectable from 300 to 9600 bps.
Format: Asynchronous, 7 or 8-bit (software
selectable).
Parity: None, odd, or even (software selectable).
Termination Load: 140 Ω, jumper selectable.
LED INDICATORS
Individual LEDs for RXD, TXD, DTR, DCD, CTS,
and RTS signals not all apply to EIA-422/485
(RS-422/485) communications.
POWER REQUIREMENTS
