Remote Scanner Control Protocol

Uniden Models BC895XLT, BC245XLT and BC780XLT

The BC895XLT, BC245XLT, BC780XLT and Pro-2052 radios can all be controlled remotely by just about any device programmed to communicate over an RS-232C style serial port. Control is accomplished by sending a command (usually just two letters) followed by a carriage return. The radio will respond with OK for okay, NG for no good, or some other usually short message which is also almost always followed by a carriage return. The command set for the radios is very similar but not identical. The most notable differences arise due to the differences in features offered by the radios. The 245 and Pro-2052 do not have CTCSS while the 895 does not have an EDACS trunked mode, and the BC780XLT has it all. All support Motorola I/II trunked modes. Some commands are only relevant in certain modes and will return "OK<cr>" in some circumstances and "NG<cr>" in others. An "ERR<cr>" suggests an invalid command. The following commands are common to the BC895, BC780 and BC245 radios: AC DL DS IC ID IL IS KEY LL LO LU MA MD MU PC PM PR QU RF RI RM SB SQ SS WI.. There are no commands which are unique only to the 895. These commands are unique to the 245: AL. These commands are unique to the 245 and PRO-2052: FI . These commands are unique to the 780: BA, BP, CB, EL, FP, LCD, LM, LT, TA, WA. Each command will include the following legend to indicate on which model commands are valid for. Hint for Experimenters: Any syntax returning NG indicates a VALID Command but not entered in the right mode or using the correct parameters. ERR indicates an INVALID Command.

Conventions:

variable	Italic letters indicate placeholders for information you supply.
[expressionlist]	Items inside square brackets are optional.
COMMAND	Text in red are examples of syntax. (Commands sent to the device)
RETURN	Text in blue are examples of returns. (Values returned from the device after the command has been issued)
Examples	COMMAND RETURN COMMENTS
	Commands sent to the device are in white. Results from the device are in gray. Comments are in yellow.

Instructions on programming trunk frequencies

Here's the correct method to program trunk radio frequencies into the BC245XLT using software control. I'd like to thank Kevin for his assistance with this as well as the others at the Yahoo:BC245XLT group who helped.

TR<space><bank><space><system type>
This sets the trunked system type for the bank you wish to program. <bank> is the bank letter A through J <system type> is 1=E1 2=E2-800 3=E2-900 4=E2-UHF 5=E2-Hi 6=Ed Example TR C 2 (Sets bank 4 to E2-800 system type)

KEY13H
This puts the scanner in trunk program mode

KEY02
<bank number> <bank number> is a number 0 through 9

KEY04
This is the E button on the scanner

PM<channel><space><frequency>
<channel> is a channel 001 through 300 and must have leading zeros. <frequency> is the frequency and must be in the format 99999999 with leading zeros Example PM091 08560250 Programs the frequency 856.025 into channel 91 Continue to program channels using the PM command for that bank.

KEY13
This takes the scanner out of trunk program mode The entire example above

TR C 2
KEY13H
KEY02
KEY04
PM091 08560250
KEY13
