RS-485 Termination

Both the ARC and the Control I/O feature an RS-485 termination jumper. Jumper J17 inside the Control I/O by the RS-485 jack

enables and disables termination. Jumping pins 1 and 2 = terminated, pins 2 and 3 = open. For maximum signal integrity, follow

the termination guidelines below:

RS-485 TERMINATION GUIDELINES

Daisy chain length

Termination

0 - 200 ft.

No termination required

200 - 1000 ft. (if powering over CAT-5)

Terminate at Control I/O

> 1000 ft. (or if not powering over CAT-5) Terminate at Control I/O and at the last ARC in each chain

For star configurations, terminate at the Control I/O.

MIDI I/O

With the DB15 MIDI I/O “joystick” port, the Control I/O can function as a MIDI Continuous Controller (CC) to RS-485 Controller

translator. The DB15 port uses a standard to (2) DIN 5 MIDI IN and MIDI OUT cable adapter. (Adapter not included). The

adapter is the same that most all computer sound cards with a joystick port use and is available at many computer and music

supply outlets. (Please see the SymNet Designer online help for information on how to map a MIDI Controller number to an RS-

485 Controller number in a SymNet DSP design.)

Device Address Quick Reference

Every RS-485 device (including all ARCs and Control I/Os) connected to the same SymNet Ring must be uniquely identified.

You may use the pictorial diagrams below to quickly set up and understand the device address DIP switches on the Control I/O.

Any time the DIP switches are changed, the unit must be power cycled for the changes to take effect.

Note:

The Control I/O contains field-upgradable firmware. Upgrading is facilitated by DIP switch #2 labeled “UPGRADE / RUN”.

Unless instructed by Symetrix Technical Support personnel or a Symetrix Technical Bulletin, this switch should remain in the

“RUN” position.

Control I/O DIP Switch Settings

NOTE:

For the sake of space, only switch settings for the first 8 addresses are pictured.

An address of up to 31 is possible (all DIP switches down). For systems containing

32 total Control I/O's, an address of zero (0) is available (all DIP switches UP).
