Introduction
1. Purpose
The purpose of this document is to explain in detail the commands and steps that
can be used to control a Planar VM Series display via RS232C.
2. Definitions, Abbreviations and Acronyms
ACK Acknowledge
NAK Not Acknowledge
NAV Not Available

1. Baud Rate : 9600
2. Data bits: 8
3. Parity : None
4. Stop Bit : 1
5. Flow Control : None
6. The Pin Assignments for DB9 male connector:
Male D-Sub 9-Pin (outside view)
Note: Use a crossover cable (null modem) for connection to the host controller:
Planar VM Series displays use RXD, TXD and GND pins for RS232C control. For RS232C
cable, use the reverse type cable.

4. Communication Procedure
Send control commands from a host controller via the RS232 connection. Do not send a new
command until the previous command is acknowledged. However, if a response is not received
within 500 milliseconds, a retry may be triggered. Every valid command receives an ACK. A
command that is valid, but not supported in the current implementation, will be responded to
with NAV (Not Available). If the command buffer is corrupt, (transmission errors) the command
will be responded to with NAK. The display operates according to the received command. If the
command is a valid “Get” command, the display responds with the requested info. If the
command is a valid “Set” command allowed, the display performs the requested operation.
Note: For LAN control, the port number is 5000

6. Communication Control
This defines the feedback command from the monitor to the host controller. When the device
receives a display command from the host controller the command reported to host controller
will be ACK, NAK or NAV.

power turns on or resumes after a power interruption.
Last Status: The monitor will be automatically switch to the last status (either Power Off
or On) whenever the main power turns on or resumes after a power interruption.
