We now have a source for some hybrid PC Boards.You can use the schematic and parts list below until your service manual The schematics and parts list for the RIB as well as some cable pinouts. This is the service manual for the RLN4008B and contains I strongly recommend that you order part number 6880309C92 from Motorola This checkbox would mimic what's available in Lab/Depot CPS.The RLN4008B Radio Interface Box (RIB) IF YOU NEED TO PROGRAMĪ MOTOROLA RADIO, YOU PROBABLY NEED THE RLN4008B RADIO INTERFACE BOX (RIB). We just need to trace out the offset, first. The coding team is also working on a modification to the ASTRO Portable/Mobile CPS release which will add a checkbox in the Radio Wide/Advanced tab, for the enabling/disabling of the ASK/ACK "Write Protected" flag.

If someone wants to research/post the data for that tier, it would be fantastic. I have not successfully mapped them out yet, but the ASK/ACK flag is most likely in the radio-wide block, which is just after the second instance of the model/serial strings. However, the offsets and data value(s) used, seem to be different. The ASTRO Saber, XTS3000 and ASTRO Spectra CPS and codeplug structure is VERY MUCH the same. You must correct any EOL (and EOB?) checksums after changing the status of this flag. In the MCS2000 codeplug, the ACK/ASK status is located at 0x37B. If the byte is E2, (1110, 0010), you would set it to 62. So if you see 1000 (on, off, off, off), it's active. In binary, the status is represented by the first flag, in the first bit of the byte. In the MTS2000 codeplug, the ACK/ASK status is located at 0x28E. Obviously some of you are intelligent enough to be aware of how to get around this issue (force a new s-record in, or play with Lab), but for those who want to do things the hard/technical way, here's the information: This essentially means if you're ASK/ACK'd, your radio is a doorstop. When the ASK/ACK is enabled, one cannot write to the radio unless the ASK/ACK is connected to the programming computer.

For those who like to play around, I have traced out the offsets and data for enabling/disabling the Advanced System Key (ASK) or Advanced Conventional Key (ACK) in the codeplug dataspace.
