USER’S GUIDE
Designed to be networked with TRANSITION Networks PowerStar
™
hubs, the TRANSITION Networks PowerStar Express Multiplexer
(PSM-8E) is a site-configurable multiplexer used for extending IBM 5250*
protocol network distances over fiber.
*IBM 5250 protocol products include the IBM
®
System 34, 36, 38, and
AS/400, remote controllers, and many supporting devices manufactured
by IBM and other companies.
The PSM-8E allows multiple AS/400, System 3x, or remote controller
polling groups to be transmitted over a single fiber-optic pair, providing
maximum throughput in either 1 Mb/s Optimized mode or in 2 Mb/s
Express mode by transparently multiplexing the 5250 "split-polling"
feature. (All new IBM controllers support "split-polling" as a means of
achieving higher throughput rates, even when connected to standard
legacy devices. The PSM-8E uses "split-polling" to increase performance
up to four times over the standard legacy 1 Mb/s 5250 protocol.)
NOTE: Refer to IBM 5250 Express reference material available from
network vendors when installing the PowerStar Express Multiplexer or
PowerStar
™
in a 5250 Express network.
