2-6 Installation
Cable Specifications Table 2-2 below shows the transmitter wiring connections using the
standard GE XMO2 4-wire cable [P/N X4(L), where L = length in ft].
This cable can be used for distances up to 450 ft (137 m).
If you are using your own cable to wire the XMO2, refer to Table 2-3
below for cable requirements.
Table 2-4 below shows the connections for the GE standard 3-wire
RS232 cable (P/N 704-667, 668, 669, or 670-L, where L = length in
ft), which is available with a DB-9 or a DB-25 connector (male or
female). This cable is available in standard lengths of 6 ft and 12 ft.
See the EIA-RS Serial Communications booklet (GE document
#916-054) for a more detailed discussion of RS232 wiring.
Note: See Figure B-4 on page B-4 for detailed drawings of the
standard GE cables described above.
