SeaI/O User Manual
Cabling Options
CA239 – 5” CAT5 RS-485 Interconnect Cable, used to connect SeaI/O modules
together in a stack (included in 4xxN SeaI/O expansion modules)
CA246 – 7’ Blue Ethernet Patch Cable. Can be used to connect SeaI/O Ethernet
modules to a hub (included with 4xxE SeaI/O Ethernet modules). Can be used to
connect SeaI/O RS-232 modules to both Sealevel and standard RS-232 serial ports
(included with 4xxS SeaI/O RS-232 modules as part of p/n: KT119). Optionally, it
can be used as an RS-485 interconnect cable to cascade additional SeaI/O modules
via the RS-485 In/Out ports on the side of SeaI/O modules
CA251 – 7’ Yellow Crossover Cable. Used to connect SeaI/O Ethernet modules
directly to a computer’s Ethernet port without having to go through a hub or switch
CA247 – 10’ Blue Ethernet Patch Cable. Can be used to connect SeaI/O Ethernet
modules to a hub, or can be used as an RS-485 interconnect cable to cascade SeaI/O
modules via the RS-485 In/Out ports
CA179 – USB 6’ A to B Cable (included with 4xxU SeaI/O USB modules)
KT119 – RS-232 DB9/RJ45 Kit, includes (DB109) DB9F to RJ45 adapter with RS-
232 pinout, and (CA246) 7’ CAT5 patch cable. For connecting SeaI/O modules to
both Sealevel and standard RS-232 serial ports (included with 4xxS SeaI/O RS-232
modules)
KT120 – RS-422 DB9/RJ45 Kit, includes (DB110) DB9F to RJ45 adapter with RS-
422 pinout, and (CA246) 7’ CAT5 patch cable. Optional accessory for connecting
SeaI/O modules to Sealevel RS-422 serial port products
KT121 – RS-485 DB9/RJ45 Kit, includes (DB111) DB9F to RJ45 adapter with RS-
485 pinout, and (CA246) 7’ CAT5 patch cable. Optional accessory for connecting
SeaI/O modules to Sealevel RS-485 serial port products
