CHAPTER 3: Getting Started
3. Turn ON the PC and run ProComm (or a similar communications
program). Go on to Section 3.3 .

ONNECTION ACROSS A

INK
If you want to, you can perform first-time configuration across a modem link
instead of through a direct connection. Take these steps:
1. If you haven’t already done so, run a normal modem cable from the
remote PC’s COM port to the remote modem’s serial port. Make sure
you connect this cable to the COM port used by your communications
program.
2. Attach an appropriate modular adapter to your local modem’s serial
port.
3. Plug one end of one of the modular flat-satin cables included with the
PM Switch into the unit’s Port 1. Plug the other end of the cable into the
adapter you just attached to your modem’s serial port. (If you want to
use a different cable to make this connection, it must be a six-wire,
straight-through-pinned twisted-pair [our product code EYN725MS] or
flat-satin [our product code EL06MS] cable with RJ-11 male connectors.)
4. Turn ON the remote PC and run ProComm (or a similar
communications program). Go on to Section 3.3 .
3.3 Applying Power to the PM Switch
Connect a power cord to the IEC 320 male inlet on the rear panel of the PM
Switch. (A power cord is included with the 115-VAC versions of the
PM Switches.) Plug the other end of the cord into a working AC outlet. Move
the PM Switch’s ON/OFF switch to ON. The PM Switch’s ON LED should
light, and its RDY LED should begin to flash.
NOTE
If all of the PM Switch’s Port Activity LEDs flash when you power up the
box, this may indicate a problem with the PM Switch unit. Please contact
Black Box for technical support as described in
Section 9.1 .
