128 H201Ti's via a single RS-232 or USB port, either locally or
remotely through an optional modem
• H201Ti's (supervisory link)
• H201Ci Controllers (H201Ci-C's and/or H201Ci-1's) in the network
(RS-485 link)
• A host computer (RS-232 or USB link)
• 2,000-V RMS isolated
• A 2-twisted-pairs (16 or 18 AWG) cable with overall shield is
required per H201Ti
• Maximal length (all cables added up): 1,200 m (4,000 ft)
• Power supply: Separate, isolated, impedance-protected, +15 Vdc
• Standard RS-485 communication port allows daisy-chaining of up
to 32 H201Ci Controllers (H201Ci-C's and/or H201Ci-1's) via the
Main Terminal Block
• One twisted triad (16 or 18 AWG) with overall shield required
• Maximal total daisy-chain length: 1,200 m (4,000 ft)
(type-B connector)
• Allows serial communications with a local host computer (or
remotely with optional modem)
• Any H201Ti can be accessed through any H201Ci Controller in the
local network
