V.35/EIA-530 user-programmable data port
The user-programmable V.35/EIA-530 data port connects to data terminal equipment
(DTE) through a 25-pin socket (female) connector. When set to EIA-530, the port also
supports RS449 and X.21 interfaces with appropriate cables and adapters.
Maximum cable lengths
V.35 = 50 ft (15.2 m)
EIA-530, EIA-449 (RS449), X.21 = 200 ft (61 m)
NOTE
Use cables that are 10 ft. or shorter when the data port clock rate is greater than 2 MHz.
Pinouts
For EIA-530, see Table 5 on page 47 .
For V.35, see Table 6 on page 48 .
Signal requirements
The attached DTE must be capable of asserting DTR and RTS.
xx is length in feet. Call the factory for available lengths.
