Simplex or Duplex
The receiver can be set in either Simplex or Duplex by installing jumpers marked SX or DX respec-
tively. In the Duplex mode, the receiver is always enabled. In the Simplex mode, the receiver is
under RTS control. If the RTS jumper is not installed, the receiver is disabled.
Full or Half Duplex
Either Full or Half Duplex can be selected by installing jumpers at the locations marked FDX or
HDX respectively. Also, when operating in the Simplex mode, there must be a jumper installed in
the FDX position
Watchdog
If an inverted output from the watchdog circuit (i.e., held high) is desired, you maycut the clad at
jumper location “G” and install a wire jumper at location “H” (G and H are located immediately to
the left of IC U16). The Watchdog circuit can be disabled by installing a jumper at the location
marked WDOG.
Interrupts
Interrupts coming from the Temperature Alarm circuit and/or the Serial Interface are enabled by
installing jumpers at locations marked IRQ 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15. Temperature
Alarm interrupts are selected at the jumper block labelled TMP. Serial Communication interrupts
are selected at the adjacent jumper block labelled COM. Note: Levels 10, 11, 12, 14, and 15 apply
only to AT-Bus applications.
