SHORT-HAUL MODEM-B SYNC (SHM-B SYNC)
5.2 The RS-232 Signals, Flow Control, and Synchronous Timing
The SHM-B Sync should be connected to your RS-232
device with a standard RS-232 cable. The cable must
have a DB25 male connector at the SHM-B Sync’s end.
The type of connector at the other end will depend on
what type of RS-232 device you’re attaching, and the
pinning of the cable will depend on whether the device
is a DTE or DCE:
• To connect a sync terminal, a PC running a sync
protocol, or another DB25 male sync-DTE serial
port, use a straight-through-pinned DB25 male-to-
female RS-232 cable such as our product code
ECN25C-MF.
• To connect a mux’s composite port or another
DB25 female sync-DTE serial port, use a straight-
through-pinned DB25 male-to-male RS-232 cable
such as our product code ECN25C-MM.
• To connect a sync modem, a mux’s channel port,
or another DB25 female sync-DCE serial port, use
cross-pinned DB25 male-to-male tail-circuit cable
such as our product code EYN255C.
