DATA CONNECTION

A reliable data connection begins with the right cable.

Microphone cable cannot transmit data reliably over

long distances or for long periods. For best results, use

only cable designed for RS-485 applications. One

cable for connecting the first fixture is included; you

will need additional cables to connect additional

fixtures. Your Martin dealer can supply suitable cable

in various lengths.

The MC-Showtime controller data output, which is

wired pin 1 to ground, pin 2 to signal - (cold), and pin 3

to signal + (hot), is configured for direct connection to

all MC-Showtime compatible Martin fixtures (see

“Supported fixtures” on page 11).

Connecting the data link

1 Connect a data cable to the MC-Showtime controller

data output. Lead the cable to the first fixture and plug it

into the data input.

2 Connect the data output of the first fixture to the data

input of the next fixture. Continue connecting fixtures

output to input.

3 Terminate the link by inserting the male termination plug,

included, into the data output of the last fixture. A

termination plug is an XLR connector with a 120 ohm

resistor soldered across pins 2 and 3.
