IRING
The EFIR10 connects to the RS-232 port of the Polycom unit. If you have
multiple units linked together via EF Bus or ASPI Bus, you may connect the IR10
to any linked unit as long as one of the linked units has the proper Device ID to
accept commands from the IR10.
We recommend keeping the distance from the receiver to the Polycom unit to a
maximum of 50 feet using RS-232 specification cable. You may be able to
increase that distance with Category 5 or other low capacitance cable. If you
decide to extend the length of the RS-232 cable, make sure the cable you use is
wired straight-through, i.e. pin 2-2, pin 3-3, and pin 5-5. Flow control is not
used by the EFIR10.
