Version 175-0188 Rev. C
The RS-232 transceiver may be used as a 5-wire RS-232 channel or as two 3-wire RS-232
channels at the expense of the RS-485 channel, which is connected through 0 Ω surface-
mounted resistors at R82 and R83 as shown in Figure 8(b). R82 and R83, shown in
Figure 8(b), must be removed when configuring the Intellicom for either one 5-wire RS-232
or two 3-wire RS-232. U10 and the associated bias and termination resistors (R58, R59,
and R60) must also be removed, but R82 and R83 are left installed, if you wish the TxB
and RxB RS-232 signals to be available on header J5.
Table 2(b) summarizes the options. Note that the parameters in the
function call must also be set to match the hardware configuration being used.
