Choose one SMS - 1 for all the connections described below (we’ll call this the “master”), and
then connect an RCA jack from the THRU RCA jacks of the “primary” to the Input jacks of the
“slave.” You will also need to obtain a “Mouse Extension” serial cable (available at any computer
store, from your Authorized Velodyne dealer, or from Velodyne directly) and connect the RS232
OUT port of the primary SMS
- 1 to the RS - 232 IN port of the secondary SMS - 1. Then, all
runtime commands directed at the primary SMS - 1 (such as select preset, volume, etc.) will be
communicated to the secondary SMS - 1 automatically through the serial cable. If you have more
than two SMS - 1s in your setup, simply continue the daisy chain from the secondary SMS - 1 to
the next SMS - 1 in the line (using both RCA and serial connections) and so on.
NOTE: When an SMS - 1 detects an incoming RS - 232 command, it reverts to “Slave Mode.”
This means that the SMS - 1 will no longer accept IR commands. To reestablish normal
operations, disconnect the RS - 232 cable and power cycle the unit.
Note that the daisy chain connection ONLY allows the woofers to communicate basic “run - time”
commands such as volume and preset. We recommend the following sequence when setting
up daisy
- chained SMS - 1s.
1. First, connect only the master SMS - 1/subwoofer(s) to the system. Do not connect the thru
or serial cables at this time.
2. Establish the crossover, phase, and other settings EXCEPT the EQ on the master SMS -
1/subwoofer(s) (see setup steps 1 – 17 below). Note the low pass crossover, phase and
polarity settings, then save.
3. Connect the video out of the slave SMS - 1/subwoofer(s), go to the settings screen, establish
the low pass crossover, slope, phase, polarity, and night mode settings from the master
SMS
- 1, then save settings.
4. Connect the microphone to the slave SMS - 1/subwoofer(s) and use the “self - EQ” feature
(described below) to establish room EQ for that SMS - 1.
5. Repeat steps 3 and 4 for each slave SMS - 1/subwoofer(s) in your system.
6. Reconnect the video out to the master SMS - 1/subwoofer(s), and reconnect the thru and
serial cables so that the master and slave SMS - 1(s) are daisy chained.
7. EQ the primary SMS - 1/subwoofer(s) (see steps 8 - 25). Self - EQ is NOT recommended for the
primary SMS - 1/subwoofer(s).
8. Setup is complete!
