Remote Connector
REMOTE Connector -
The Remote connector provides a way to control the VGAxi / MACxi switchers
using contact closure devices such as the following:
•
Extron KP-10 (wired remote keypad, IR-10 (infrared remote), RS-232 2-4-6-8 (Host computer)
•
Third Party Remote Control - Information below may be used to design a third party remote control.
Remote connector pin assignments are shown in the table below (Figure 4-A). To select a different
switcher input number through the remote connector, momentarily connect the pin for the desired input
number (#) to logic ground (pin 25).
NOTE __ The duration of a momentary connection is defined as 250 — 500 milli-seconds.
The Tally pins can be used for remote indication of the switcher's selected input. Tally #1 - #6 (pins
14 -19) will indicate the switcher's selected input # with a logic low (0 volts), the Tally pins are
normally at logic high (5 volts). For example, with switcher input #2 selected, the front panel LED for
that input would be ON and Tally #2 (pin 15) would be 0 volts while the remaining Tally pins would
be 5 volts.
The schematics shown below (Figure 4-B) may be used as a guide to design and build indicator
circuits for the Tally pins. An example of an LED circuit is shown at the top, two versions of
incandescent lamp driver circuits are shown below the LED circuit.
The +5 volt source on remote connector pin 13 is limited to 100mA, if a different voltage or a higher
current is required, an external voltage source will be necessary.
Looping is a configuration technique (see Figure 4-C) that enables the total number of inputs to a
switcher (A) to be increased by connecting its highest input to the output of another switcher (B). A
Loop control signal from switcher B (Loop Out - Remote connector pin 24) to switcher A (Loop In -
Remote connector pin 12) will cause switcher A to select its highest input when an input selection
is made on switcher B. If a third switcher (C) is added, its output would connect to the highest input
on switcher B and its Loop Out signal would connect to switcher B's Loop In. An input selection on
Switcher C would cause switcher B to select its highest input and signal switcher A to select its
highest input. The selected input on switcher C would be available at Switcher A's output. An input
selection on Switcher A would drop Switchers B and C out of the loop until a selection is made on
either B or C.

VGA connector pin-9 is normally not used and does not exist in most cases, however, some
equipment/applications may require the signal on input connector pin-9 to be passed to output
connector pin-9. If this is a requirement, it will be necessary to solder one or more jumpers onto the
inside of the rear panel. The jumpers (JMP1 - JMP6) are shown on the Printed Circuit Board layout
below. The switcher model determines which jumper applies to which input as follows:
SW6 VGAxi xi xi xi xi
SW4 VGAxi xi xi xi xi
SW2 VGAxi xi xi xi xi
To access the inside of the rear panel, DISCONNECT POWER and remove four screws from the top of
the switcher. The bottom panel can then be removed. Unplug the two cables connected to the circuit
board enabling it to be removed.
