Zimmerman must abide by a curfew from 6 p.m. to 6 a.m., and like before, will be monitored electronically.
Prosecutor Bernie de la Rionda argued before the judge last week that Zimmerman should remain in jail without bail because he was complicit in lying to the court and can't be trusted.
Forensic accountant Adam Magill testified that thousands of dollars in donated funds flowed into and out of Zimmerman's bank account in the days before the first bail hearing.
Magill said it appeared Zimmerman and his wife were speaking in code during recorded jailhouse telephone conversations about the amount of money involved. He also said that transferring funds between accounts could have been done to make it appear that Zimmerman had less money available for bail than he did.
De la Rionda reiterated that prosecutors believe Martin, a 17-year-old African-American, was an innocent victim who was confronted by Zimmerman without provocation.
Zimmerman, a Sanford neighborhood watch volunteer, acknowledged fatally shooting the unarmed Martin after calling police to report a suspicious person. Zimmerman, who is white and Hispanic, said Martin attacked him.
