Power supply
The MFT-XFMR accessory transformer is connected to the
unit, and supplies 24 VAC power to the ZIP-RS232 and up to
one connected actuator. The actuator on switch powers the
actuator. Separate actuator 24V may also be used.
RS232 connector
The ZIP-RS232 is connected via this RS232 connector to the PC
with a standard female-female 9-pin sub-D cable, provided.
LEDS
A Green LED is lit when 24 VAC is supplied.
Tx: LED flashes when data flows from ZIP-RS232 to actuator.
Rx: LED flashes when data flows from actuator to ZIP-RS232.
EN: LED is lit constantly when RS232 device is connected.
Accessories
Null modem serial cables can be used by switching the
ZIP-RS232 internal jumpers.
