SHORT-HAUL MODEM-B SYNC (SHM-B SYNC)
posts. (The SHM-B Sync units must both be set
to the same data rate, which they will generate
internally; the attached devices must be set to
accept clock from them.)
• Three pairs of posts are used to set the SHM-B
Sync’s CTS delay. They’re at the rear of the right-
hand side of the board (the ones labeled “CTS-
DELAY SELECTION” in Figure 3-1). The CTS delay
is the amount of time that the SHM-B Sync waits
after detecting that the attached device has raised
RTS before it responds by raising CTS. The possible
settings are LONG (53 ms), SHORT (7 ms), or
NONE. Factory default is NONE, but if your RS-232
device needs to see a CTS delay in order to function
properly, move the jumper to the appropriate post
in that SHM-B Sync only
.
Standalone units only:
To open the unit’s case, push in on
either side of the top half of the case, close to the front
of the unit, then pry the top of the case away from the
bottom half. (If your hand is large enough, you can
squeeze both sides of the case’s top half toward each
other at the same time, then pry it upward.) The halves
of the case are hinged at the back, so the unit swings
open like a compact or a makeup case.
