RS-232C (Applies to the 900-TC8 only)
• RS-232C connections are 1:1.
• The total cable length is 15m max.
• Use a shielded, AWG24 to AWG14 (cross-sectional area of 0.205 to
2.081 mm2) twisted-pair cable for the 900-TC8 and 900-TC16.
• Use a shielded, AWG24 to AWG18 (cross-sectional area of 0.205 to
0.823 mm2) twisted-pair cable for the 900-TC32.
