IRC Options” on page 128 to make these settings. If a kitchen printer or Datatran is used as a
shared device, you must identify the register where the device is connected at the program.
Note: If a new register is added to an existing IRC network, you must power on/off all
registers so the new register will be recognized.
IRC Cable Specifications
At minimum, CRS recommends Shielded Category 5e STP, 4-wire twisted pair cable, for use as
communication wiring for SPS-300 series IRC systems.
NOTE: Higher rated cables, such as Cat 6 are also acceptable.
CAT 5e STP (Shielded Twisted Pair) cable is a high quality general purpose data
communications cable that supports standard transmission protocols such as 232, 422, 485, and
10/100 Base-T Ethernet communications. CAT 5e STP cable consists of 4 pairs of stranded,
twisted pair wire, with an overall shield foil.
Note: CRS supplies different modular connectors for use with stranded or solid cable. Use
P/N 202896 with stranded cable; use P/N 202994 with solid cable.
Do not use unshielded CAT 5e, unless run alone inside conduit.
