ImageWriter II: Maximum Interface Cable Length



I want to have an ImageWriter II printer directly connected to my Macintosh
modem port (as a non-AppleTalk device), but have the printer physically located
several yards away from the Macintosh. What is the maximum cable length for
connecting an ImageWriter II directly to a Macintosh?

Tech Comm has driven an ImageWriter/ImageWriter II at distances up to 12 feet
without difficulty. The RS-232 standard specifies a maximum of 50 feet using
the maximum voltage (+/-25V).

If one side of the output device is grounded, to convert the signal from RS-422
to RS-423 signalling, the printer should workable at (approximately) a maximum
of 50 feet away.

(NOTE: Since most Macintoshes use the same output device, the 26LS30, this
information is relevant for most systems.)
