4.0 Troubleshooting

Before contacting ALI for technical support, please review the manual sections covering installation and

operation.

There are several status indicator lamps on the 2800 processor board that are quite helpful when trying to debug

problems. The POWER indicator illuminates when the processor board has power. The RXD indicator flashes

when characters are received via RS-232 or RS-485. The TXD indicator flashes when characters are transmitted

via RS-232. The ENB indicator flashes when characters are transmitted via RS-485. The RELAY indicator

illuminates when the mechanical relay output is activated.
