SAM4s SPS-300 Operator's & Programming Manual v1.4 IRC (Inter-Register Communications) Appendix • 277
IRC Programming & Setup
The only IRC settings are made by selecting IRC OPTIONS from the S-Mode menu. See.
“IRC Options” on page 121 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 the new register will be recognized.
Communication Cable Specifications
At minimum, CRS recommends Shielded Category 5e STP , 4 twisted pair cable, for use as
communication wiring for SPS-2000/SPS-5X0 system.
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.
