AC-MAX-24 USER MANUAL
RS-232 Control
The RS-232 control port located in the bottom right corner on the rear panel is used to communicate
with the AC-MAX-24 via a computer or third-party control system.
Wiring for this port uses a 3-pin terminal block connector to DB9, where only pins 2, 3, and 5 are used.
If the control devices do not have a DB9 port, a USB to DB9 adapter may be required.
For RS-232 control, use a null modem serial cable adapter and set the serial communications to:
Baud: 57600, no parity, 8 data bits, and 1 stop bit, with no handshaking.
Add a carriage return (Enter key) after each command when using direct commands. The unified
command list (ASCII) can be located
LAN Wiring
The IP control port located in the bottom right corner on the rear panel is used to communicate with
the AC-MAX-24 via a LAN, router, or third-party control system processor. For TCP/IP control,
commands use Telnet Port 23.
The recommended termination is based on TIA/EIA T568A or T568B standards for the wiring of the
twisted pair cables:
