Table 2-1: Router RS-232 Port Pin Definitions
The port can also be used to connect a remote control panel to the router. To connect to a remote panel
the port must be configured as a SMPTE 207M Tributary, as shown in Table 2-2. To reconfigure the port
the user must remove the top cover and reposition jumper J26 so that it is on pins 2 & 3 (toward header
J23) and move the ribbon cable over to J23.

Table 2-2: Router RS-422 Port Pin Definitions
GPI/O / REMOTE PANEL:
This female DB-25 pin connector provides 8 General Purpose Opto-isolated
inputs (GPIs) and 4 General Purpose isolated relay outputs (GPOs), as well as an RS-422 serial
interface for connecting the remote panel.
Vint
pr5Volts from the Router and
Vext
is used
to provide external power to the opto isolators. Typically
Vint
and
Vext
are connected together so
that the isolators may be powered from the router. Table 2-3 shows the pin definitions of the GPIO
connector. Figure 2-6 shows a schematic of the GPIO circuitry. See section 2.5 for more
information on connecting the General Purpose inputs and outputs. The functions of the GPIs and
GPOs are assigned using the Setup menu, and can be used to select crosspoints and receive
tallies from the router. See section 3.12 and 3.13 for information on setting up the GPIO operation.
